The TCW241 is an Ethernet control unit with 4 digital inputs, 4 relay outputs, 4 analogue inputs and a 1-Wire interface for up to 8 x 1-Wire sensors. The relays can be activated manually either from a web browser or from commands issued over the LAN or automatically on signal input alarm or pre-programmed timed basis. The TCW241 can also send an email alert on digital or analogue input alarm conditions. Supports MODBUS TCP/IP, SNMP.
The TCW241 is an Ethernet I/O module. It provides four digital inputs and four analog inputs. Its 1-Wire interface suppotrs up to eight sensors like temperature, humidity, CO2, AC/DC current, 4/20mA etc. The Ethernet I/O module has real-time clock (RTC) with time server synchronization (NTP) for advanced relay scheduler. It can be used for one-time or repetitive (weekly) tasks to turn on/off relays at previous set times.
The 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 monitored parameters. HTTP post can be send periodicaly or on previous set alarm conditions.
The relays of 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..
The TCW241 has a built-in web server that provides simple web interface. The device can be accessed directly, using a standard web browser, installed on users’ computer or smart phone.

TC Monitor Software
TC Monitor is easy to use Windows application for monitoring and control of TCW products. TC Monitor can collect and display data from controllers installed in different locations (sites). The collected data is stored in SQL database and can be displayed or exported in MS Excel format for further analysis. TC Monitor has a simple web interface, which enables easy and fast configuration. Monitored parameters can be 1-wire sensors, digital and analog inputs and relay outputs.
The free version of TC Monitor provides 10 credits, this means up to 10 different parameters can be monitored and logged. More Information >>
