Connectors

Type: 3.81mm pitch screwless pluggable; Wire range: 28 to 16 AWG / 0.081 to 1.31 mm²;

Type: 5.00 mm pitch screwless push-in; Wire range: 24 to 12 AWG / 0.2 to 2.5 mm²;

Note: For currents up to 10 A, it is recommended to use wires with a minimum cross-section of 1.5 mm² (approximately 16 AWG) to ensure safe operation and minimal voltage drop.

2-pin – current input connector

Pin	Label	Description
1	~/-IN	Current input terminal (-)
2	~/+ IN	Current input terminal (+)

Note: Polarity matters only in DC mode. In AC mode, the input is non-polarized.

5-pin – power and communication connector

Pin	Label	Description
1	+4.0 to 5.5 V	Power supply input
2	GND	Ground
3	1-Wire	1-Wire data line
4	GND	Ground(duplicated)
5	MODE	Measurement mode selection

The MODE pin on the TERACOM TSC201 has the following functions:

• Floating/unconnected – DC current measurement

• Connected to GND – AC current measurement

This device must be installed only by qualified personnel.

Improper handling or installation may result in electric shock, equipment damage, or personal injury.

The current input terminals may be connected to circuits carrying high voltages via current transformers.

Always ensure that power is disconnected before wiring, and observe all relevant electrical safety regulations.

The device should be installed in a dry, well-ventilated electrical enclosure, ensuring safe and stable operating conditions.

DIN Rail mounting

The device is designed for installation on a standard 35 mm DIN rail (EN 60715). To mount the module:

• Tilt the upper part of the housing toward the rail and hook it over the top edge.

• Press the lower part gently until it clicks into place.

• Ensure the module is firmly secured and does not move along the rail.

Wire Interface

It is strongly recommended to use only UTP or FTP cables for the 1-wire interface to ensure reliable communication. The total cable length should be kept up to 30 meters. For connecting multiple sensors, it is strongly recommended to use a “daisy-chained” (linear) topology rather than a star or branched topology to minimize signal reflections and ensure stable operation.

The device uses a single LED, visible through the semitransparent front panel, to indicate its current status:

• Blinking every 1 second – device is operating normally; communication with the controller is active;

• Blinking every 3 seconds – no communication with the controller;

• LED is off – no power supply.

The TERACOM TSC201 sensor is compatible with the following Teracom modules:

• TCW220;

• TCG120-4E;

• TCG140-4E;

• TCW241;

• TCG120-4G;

• TCG140-4G.

If you wish to integrate support for this device into a third-party master device, please contact your dealer for the exact commands and specifications of the 1-Wire interface. This will ensure correct communication and full compatibility with the sensor.

Please recycle all applicable materials in accordance with local regulations.

Do not dispose of the device as regular household waste. Electronic components should be properly recycled to minimize environmental impact.
