Each TCW122B-RR is an Ethernet based I/O module that has two digital inputs and two relay outputs. Two units can be paired in order to seamlessly send digital IO data to the other paired device. So, a contact closure at one unit, say from an alarm panel, will activate the corresponding relay at the other unit, to say sound a siren. Data is bi-directional. Supplied as a pair
TCW122B-RR is an Ethernet controller with embedded WEB server for set up. The device has two digital inputs and two relays, with normally open and normally closed contacts.
TCW122B-RR can works in two modes – “Client” or “Server”. The “Client” sends periodically the status of its digital inputs to “Server”. As an answer, the “Server” returns its digital input status. Activating the input of “Client” switches on the relay of “Server” and vice versa. This configuration is used to control remotely devices without a browser or to extend a digital signal to a remote location on the network.
Client-server model of TCW122B-RR allows connecting the devices in different networks:
