The TCW181B-CM is an 8-channel Ethernet digital IO module. The device can be controlled via WEB interface, SNMP applications or user application over HTTP / XML API commands. It can be used as a standalone module or as part of control and monitoring systems.
The TCW181B-CM IO module has eight relays with normally open and normally closed contacts with up to 3Amp, either AC or DC power. All eight relays on the unit can be activated independently or simultaneously. Supported M2M Protocol - SNMP v.1 makes TCW181B-CM a good choice as a controller of systems with SNMP management software.
Ethernet digital IO module supports a digital input that can work either in "dry contact" or " logic level "mode. The choice is with hardware that can be set using jumper, close to the entrance. Each change of input status can generate an email or SNMP trap if this feature is enabled.
