Figure 2. Installing the cFP-DO-400 Wiring the [c]FP-DO-400 The FP-TB-x terminal base has connections for each of the eight output channels and for an external power supply to power the output channels and field devices. The cFP-CB-x connector block provides the same connections. Each channel has one output terminal (VOUT), one supply terminal (VSUP), and two common terminals (COM). All eight channels are referenced to the COM terminals. The V and VSUP terminals are all internally connected, as are the C and COM terminals. © National Instruments Corp. 3 FP-DO-400 and cFP-DO-400 Use a 5–30 VDC external power supply for the output channels. The power supply must provide enough current to power all of the loads on the output channels, up to 1.5 A per channel.1 Connect the external multiple power C and supply to multiple COM terminals as V needed and Vto SUP ensure terminals that the and to maximum current through any terminal is 2 A or less. Install a 2 A maximum, fast-acting fuse between the external power a 1.5 A supply maximum, and the fast-acting VSUP terminal fuse suitable on each for channel. the load Install at the VOUT terminal. Figure 3 shows fuses where appropriate. Figure 3. Recommended Field Connections Table 1 lists the terminal assignments for the signals of each channel. Terminal assignments are also listed on the side panel of the cFP-DO-400 and under the slide-in card on the front of the FP-DO-400. 1 Refer to the Digital Output Circuit and Specifications sections for the maximum output current level on all channels. 5–30 VDC External Power –Supply + VVSUP 2 A max VOUT 1.5 A max Load COM [c]FP-DO-400 C To next channel FP-DO-400 and cFP-DO-400 4 ni.com Table 1.

SUP terminal. Digital Output Circuit The [c]FP-DO-400 digital output channels are optically isolated from the rest of the FieldPoint bank. The channels are sourcing outputs, which means that the output terminal provides a path to a voltage supply. In the ON state, a transistor is turned on between the positive external supply voltage (V and VSUP) and the output terminal (VOUT). In the OFF state, this transistor is turned off, allowing only a small leakage current to flow. Ensure that the load on any channel does not draw more than 1.5 A, and the sum of the squares of the total current supplied by all channels at any time is no more than 8 A2. To determine whether the total current is within the limit, square the current on each channel and add the squares together. If the sum of all the squares is less than or equal to 8 A2, the total current is within the limit. In the following example, three channels supply 1.5 A each and one channel supplies 1 A: (1.5 A)2 + (1.5 A)2 + (1.5 A)2 + (1 A)2 ≤ 8 A2 © National Instruments Corp. 5 FP-DO-400 and cFP-DO-400 Caution The outputs must not be short-circuited to the potential of the C or COM terminals (the negative voltage of the external supply). Short circuits damage the [c]FP-DO-400 output channels. Check all wiring carefully before applying power. In and causes the the ON a supply voltage state, voltage the drop effective between (V and resistance Vthe SUPexternal ) is between 0.3 supply Ω. This the voltage resistance output and (VOUT) the output voltage. Table 2 lists the actual output voltages based on the voltage provided by the external power supply. Table 2. [c]FP-DO-400 Output Voltages for a 0.5 A Current Flow V VOUT 5 4.85 10 9.85 12 11.85 24 23.85 30 29.85 If the external power supply you are using does not provide one of the voltages in Table 2, use the following equation to calculate the actual voltage output. ActualOutput = Vext – (Iflow × 0.3 Ω) where ActualOutput is the voltage sourced by VOUT Vext is the voltage provided by the external power supply Iflow is the current flow through the VOUT terminal Note Using a 5–10 V external supply increases the output impedance to 2 Ω. This increase limits the amount of current each channel can supply. Refer to the Specifications section for more information. Table 3 shows some common combinations of output current levels on several channels. Combinations are valid from –40 to 50 °C for the cFP-DO-400 and from –40 to 70 °C for the FP-DO-400.

This flyback voltage can damage the output and the power supply. It is best to limit flyback voltages by installing a flyback diode across an inductive load. Typically, you should mount the flyback diode within 18 in. of the load. Figure 4 shows one channel connected to an inductive load with a flyback diode. VVSUP COM C Flyback Diode for Inductive Load Figure 4. Digital Output Circuit (External Power Supply Not Shown) The [c]FP-DO-400 contains flyback diodes to prevent excessively high voltage from damaging the module. National Instruments still recommends using an external protection circuit across any inductive load.VOUT 1.5 A max Load [c]FP-DO-400 © National Instruments Corp. 7 FP-DO-400 and cFP-DO-400 Status Indicators Figure 5 shows the status indicator LEDs on the [c]FP-DO-400. Figure 5. Status Indicators The [c]FP-DO-400 has two green status LEDs, POWER and READY. After you install the FP-DO-400 onto a terminal base or the cFP-DO-400 onto a backplane and apply power to the connected network module, the green POWER indicator lights and the [c]FP-DO-400 informs the network module of its presence. When the network module recognizes the [c]FP-DO-400, it sends initial configuration information to the [c]FP-DO-400. After the [c]FP-DO-400 receives this initial information, the green READY indicator lights and the module is in normal operating mode. In addition to the green POWER and READY indicators, each channel has a numbered, green output state indicator that lights when the channel is in the ON state.

Isolation and Safety Guidelines Caution Read the following information before attempting to connect the [c]FP-DO-400 to any circuits that may contain hazardous voltages. This section describes the isolation of the [c]FP-DO-400 and its compliance with international safety standards. The field wiring connections are isolated from the backplane and the inter-module communication bus. The isolation is provided by the module, which has optical and galvanic isolation barriers designed and tested to protect against transient fault voltages of up to 2,300 Vrms. FP-DO-400 and cFP-DO-400 8 ni.com Follow these guidelines to ensure a safe total system: • The [c]FP-DO-400 has a safety isolation barrier between the I/O channels and the inter-module communication bus. There is no isolation between channels unless otherwise noted. If any of the channels on a module are wired at a hazardous potential, make sure that all other devices or circuits connected to that module are properly insulated from human contact. • Do not share the external supply voltages (the V and C terminals) with other devices (including other FieldPoint devices), unless those devices are isolated from human contact. • For Compact FieldPoint, you must connect the protective earth (PE) ground terminal on the cFP-BP-x backplane to the system safety ground. The backplane PE ground terminal has the following symbol stamped beside it: . Connect the backplane PE ground terminal to the system safety ground using 14 AWG (1.6 mm) wire with a ring lug. Use the 5/16 in. panhead screw shipped with the backplane to secure the ring lug to the backplane PE ground terminal. • As with any hazardous voltage wiring, make sure that all wiring and connections meet applicable electrical codes and commonsense practices. Mount terminal bases and backplanes in an area, position, or cabinet that prevents accidental or unauthorized access to wiring that carries hazardous voltages. • Operate the [c]FP-DO-400 only at or below Pollution Degree 2. Pollution Degree 2 means that only nonconductive pollution occurs in most cases. Occasionally, however, a temporary conductivity caused by condensation must be expected. • Refer to the FieldPoint product label for regulatory certification under hazardous location standards. If the FieldPoint product is not certified for operation in hazardous locations, do not operate it in an explosive atmosphere or where there may be flammable gases or fumes. © National Instruments Corp. 9 FP-DO-400 and cFP-DO-400 Specifications These specifications are typical for the range –40 to 70 °C unless otherwise noted.
