TCW280Analog output module Overview TCW280 is an analog output module with an Ethernet interface and galvanic isolation between power supply and outputs. It has 2 analog output channels. Every channel can work either in voltage (0/5 or 0/10V) or current loop (0/20, 4/20 or 0/24mA) mode. Generated signals have excellent stability and 12-bit resolution. The device has also 4 digital (open-drain) outputs. The digital outputs work in two modes ON/OFF or PWM. In ON/OFF mode they can be used as a standard digital output to control devices with dry contact activation. In the PWM mode, the output can be used as an "analog" output for appropriate processes. TCW280 has also 2 relays with normally closed and normally open contacts. Both relays can be activated from the WEB interface, M2M protocol or by the schedule. The module supports MODBUS TCP/IP, SNMP, and HTTP API for M2M communication.
