1. Short description
TCW280 is an analog output module with 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
– DC motor control, LED dimming, etc. The frequency in PWM mode can be up to 2 kHz.
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 scheduling functionality offers 4 different schedules for single or repeated (weekly) tasks.
The module supports MODBUS TCP/IP, SNMP, and HTTP API for M2M communication.
