Model Ethernet digital IO module TCW181B-CM

HTTP API and SNMP v1 support for data acquisition (SNMP manager) software applications.

The TCW181B-CM is 8-channel Ethernet digital IO module. The device is manageable by WEB interface, SNMP programs or user application over HTTP/XML API commands. It can be used as a stand-alone device or as a part of control and monitoring systems.

The IO module TCW181B-CM has eight relays with normally open and normally closed contacts for up to 3 Amperes either AC or DC current. All eight relays of the device can be activated independently or simultaneously.

Supported M2M protocol – SNMP v.1 makes the TCW181B-CM good choice for controlling systems with SNMP manager software.

Ethernet digital IO module supports one digital input, which can work either in “dry contact” or “logic level” mode. The mode is hardware settable by a jumper.

Every change of status of the input can generate an e-mail or SNMP trap if this function is enabled.
