Ethernet I/O module TCW241
1.
Introduction
TCW241 is an Ethernet IO module, the right choice for factory automation and distributed process
control. It has 4 digital inputs, 4 analog inputs and 4 relays with normally open and normally closed
contacts.
Ethernet I/O module supports up to eight Teracom 1-Wire sensors for temperature, humidity, CO2,
current, 4/20mA, galvanic isolated analog voltage etc.
The relays can be activated either remotely (WEB, SNMP, HTTP API, MODBUS/TCP, etc.) or locally
–
from
the status of a monitored parameter (1 Wire sensor, analog voltage, and dry contact).
An XML / JSON file with all monitored parameters can periodically upload on a dedicated server with
HTTP/HTTPS. Like answer server can return commands for relay's control. This is a way for building
SCADA system. For every parameter email and SNMP traps for up to 5 recipients can be sent. Alarm alert
also can be sent by HTTP/HTTPS Post with XML/JSON status files.
An embedded real-time clock provides scheduled time control of selected outputs: the tasks can be
either single or with weekly repetition.
