This Relay Controller Module serves as the host to the Solid State Relay Module (part number WTSSR-M). The Controller can work in conjunction with, or take the place of a PC. It communicates with the Relay Module using its command set in the same way as a PC and allows manual operation of each relay via a remote data link. Switches wired to the inputs of the Controller will be able to set the on/off states of up to 10 relays, two WTSSR-M units.
