TCW241 is an Ethernet IO module with Modbus TCP/IP support. It is intended for use in monitoring and controlling general remote Ethernet IO. The device features 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 Ethernet IO module's relays can be activated both remotely and locally. Remote activation includes a user-friendly WEB interface or M2M protocols. Local activation is possible from a schedule, the status of a single parameter, or custom functions. The function can include up to four parameters.

The module supports MODBUS TCP/IP, SNMP, and HTTP API.

The module has a real-time clock with time server synchronization. It is used for advanced relay scheduling. Advanced scheduling can be used for one-time or repetitive (weekly) tasks to activate/deactivate relays at preset times.

TCW241 can initiate a connection (HTTP Post) to dedicated remote servers. The payload of this post is an XML or JSON file. The files contain the current values of the monitoring parameters. The HTTP message can be sent periodically or based on previously set alarm conditions.
