TCW241 is an Ethernet IO module, the right choice for factory automation and distributed process control.

TCW241 is an Ethernet IO module with Modbus TCP/IP support. It is intended to use for general remote Ethernet IO monitoring and control. The device has four digital inputs, four analog inputs, and four relays. Its 1-Wire interface supports up to eight 1-Wire sensors for temperature, humidity, carbon dioxide, AC or DC current, etc.

The module has a real-time clock with time server synchronization. It is used for advanced relay schedule. The advanced schedule can be used for one-time or repetitive (weekly) tasks to turn on/off relays at previous set times.

Friendly WEB interface for simple configuration and control;
4 digital “dry contact” inputs for direct monitoring of relay outputs;
4 analog inputs with 0 to 60VDC range for telco battery monitoring;
Multiplier and offset for analog inputs and some sensors;
1-Wire interface for up to 8 sensors (up to 16 parameters);
4 high current relays with normally open and normally closed contacts;
MODBUS TCP/IP support;
SNMP v2 support with trap alerts to up to 5 recipients;
4 schedules for real-time control of relay outputs;
Custom made logical functions for flexible activation of relay outputs;
Secured email transfer with TLS 1.0, TLS 1.1 and TLS 1.2 support;
XML/JSON and HTTP API commands for client-server systems;
Dynamic DNS support for DynDNS, No-IP and DNS-O-Matic providers;
Network time protocol (NTP) support for time synchronization;
Remote firmware update via standard browser;
Rugged DIN-Rail/wall-mountable enclosure.
