TCW122B-CM Remote IO Module

Easy Setup Remote IO Modules TCW122B-CM

An Ethernet network-compatible remote IO module for environmental monitoring and control, the TCW122B-CM The Web interface, SNMP software, and user applications can all be used to manage it.
Two relays with ordinarily open and normally closed contacts are present in the remote IO module. Both relays have the ability to be remotely activated via the WEB interface, SNMP managers, and HTTP/XML API commands, as well as locally, based on the state of the monitored parameters.

The TCW122B-CM features 1-Wire interface support, allowing for the connection of up to two temperature or humidity-temperature sensors. In addition to monitoring ambient conditions, it can also track two analog voltages and the status of two digital inputs. It's capable of sending email notifications and/or SNMP traps for any alarm situation related to these parameters. This controller is versatile and can function both independently and as an integral component within data acquisition (SCADA) systems.

Features

  • Intelligent monitoring and management of temperature and humidity.
  • Web-based configuration and control with password protection.
  • Utilizes a 1-Wire interface, supporting up to 2 temperature sensors.
  • Equipped with 2 analog inputs, ranging from 0 to 60VDC.
  • Features 2 digital inputs, which can be set to 'dry contact' or 'logic level' modes.
  • Includes 2 relay outputs with both Normally Open (NO) and Normally Closed (NC) contacts.
  • Capable of sending email alerts for specific conditions.
  • Supports SMTP with authentication (please note that SSL/TLS is not supported).
  • Offers SNMP version 1 (SNMPv.1) for network management.
  • Sends SNMP traps to notify about alert conditions.
  • Provides HTTP and XML API commands for seamless integration.
  • Supports remote firmware updates

Applications:

  1. Remote monitoring and control of environmental conditions in data centers.
  2. Regulating temperature and humidity levels for food and pharmaceutical storage.
  3. Managing electrical devices remotely.
  4. Security and alarm systems for homes and offices.
  5. Automation of industrial processes.
  6. Control and administration of small to medium-sized networks.
