5.3.1. Power supply connection
TCW280 is designed to be supplied by adapter SYS1308-2412-W2E or similar, intended for use in
the conditions of overvoltage category II. The power supply equipment shall be resistant to short
circuit and overload in a secondary circuit.
When in use, do not position the equipment so that it is difficult to disconnect the device from the
power supply.
5.3.2. Analog outputs
TCW280 has two isolated analog channels. Every channel can be programmed to work either in
voltage or current loop mode. In the voltage mode, two ranges are supported - 0 to 5 and 0 to 10
volts. In the current loop mode, three ranges are supported – 0 to 20, 4 to 20, and 0 to 24 mA. In
the current loop mode, there is an alarm notification for open loop.
Voltage and current loop outputs are single-ended and are assigned to different connectors. Using
the selected mode requires connecting to the appropriate connector.
