TCW181B-CM Ethernet Digital IO Module

The TCW181B-CM is an 8-channel Ethernet digital I/O module. This versatile device can be managed via a WEB interface, SNMP programs, or user applications using HTTP/XML API commands. It can serve as a standalone unit or integrate seamlessly into control and monitoring systems.

The TCW181B-CM I/O module features eight relays, each equipped with both normally open and normally closed contacts, capable of handling up to 3 Amperes of AC or DC current. These eight relays can be activated independently or simultaneously, providing flexible control options.

With support for SNMP version 1, the TCW181B-CM is an excellent choice for systems controlled by SNMP manager software, making it a reliable option for managing and monitoring various processes.

Additionally, this Ethernet digital I/O module offers a single digital input, which can operate in either 'dry contact' or 'logic level' mode. The mode can be set via a hardware jumper located near the input. Any change in the input status can trigger email notifications or SNMP traps, provided this function is enabled.

Key Features:

• Secure web-based configuration and control with password protection.
• A single digital input offering both 'dry contact' and 'logic level' modes.
• Eight relay outputs with both Normally Open (NO) and Normally Closed (NC) contacts.
• Support for SNMP version 1 (SNMP v.1) for efficient network management.
• Capability to send SNMP traps for alert conditions.
• Email alerts for notifying about critical conditions.
• SMTP support with authentication (please note that SSL/TLS is not supported).
• Accessible through XML and HTTP API commands for seamless integration.
• Remote firmware updates for ongoing improvements.
• Housed in a robust DIN-Rail or wall-mountable enclosure for durability and versatility.

Use Cases:

• Remote control of electrical devices via relay.
• Security and alarm systems for homes and offices.
• Automation of industrial processes.
• Management of energy output in wind and solar power systems.
