TCW241 is an Ethernet I/O module. It provides four digital inputs and four analog inputs. Its 1-Wire interface supports up to eight sensors like temperature, humidity, CO2, AC/DC current, 4/20mA etc.
The Ethernet I/O module has a real-time clock (RTC) with time server synchronization (NTP) for advanced relay schedule. It can be used for one-time or repetitive (weekly) tasks to turn on/off relays at previous set times.
TCW241 can initiate a connection (HTTP Post) to remote dedicated servers. The payload of this post is XML or JSON file, with current values of monitoring parameters. HTTP post can be sent periodically or on previous set alarm conditions.
The relays of the Ethernet I/O module can be activated either remotely or locally. So-called remote activation includes friendly WEB interface or M2M protocols – MODBUS TCP/IP, SNMP, and HTTP API.
The local activation is possible from scheduler, status of single parameter or by custom made functions. They can include up to four parameters.

*Caution. Teracom's Ethernet Controllers do not include power supply in their packaging and in case of purchase, you will need to order a power supply separately if you do not already have a compatible power supply.
