TCW240B is a controller for monitoring and control in Ethernet networks. It is based on Microchip chipset. The device has 4 digital and 4 analog inputs, 1-Wire interface for up to 8 Teracom’s 1_wire sensors like temperature, humidity, CO2, current etc. It also has 4 relays with normally open and normally close contacts.
The relays can be activated either remotely (WEB, SNMP, HTTP etc.) or locally - from status of monitored parameter (1 Wire sensor, analog voltage and dry contact). Only one parameter can manage the relay at the same time, but for every parameter can be sent e-mail/SNMP trap for alert conditions.
Embedded real time clock gives a possibility to arrange scheduled task in time. The tasks can be either single or with weekly repetition.
