Remote relay control module TCW122B-RR

Tunnels a digital input to a relay output on a remote unit via Ethernet.

Description

TCW122B-RR is a remote relay control module based on Ethernet, with two digital inputs and two relay outputs, featuring normally open and normally closed contacts.

The device is intended to operate in pairs, where two identical units are configured in a client-server mode to enable remote transfer of digital input states.

The Client unit periodically sends the status of its digital inputs to the Server unit, which processes this information and switches its relay outputs accordingly.

The client-server architecture allows flexible deployment in different network environments depending on the application requirements and system topology.

Both devices can operate within the same local network using private IP addresses or be connected over the Internet using public IP addresses in real installations.

Hybrid configurations are also supported, where one unit is located in a local network, and the other is accessible through a public IP address, including scenarios with port forwarding behind a router.

Features

Password-protected web-based configuration interface. Provides secure access to the device settings through a standard web brows.
Two digital inputs with dry contact and logic level modes. Allows flexible connection to external sensors, switches, or control signals.
Two relay outputs with normally open and normally closed contacts. Enables reliable switching of external devices and loads.

Encrypted communication between paired devices. Ensures secure data exchange in client-server operation over IP networks.
Manual or DHCP-based network configuration. Supports both static IP addressing and automatic network setup.
Remote firmware update capability. Allows device firmware to be updated remotely without physical access.
