Description
The CA-A460-P Relay Expansion Module is designed to enhance the CT-V900-A Controller by offering an additional seven relays. Each controller can support up to two “plug and play” relay expansion modules, bringing the total relay count to 16 per controller. These relay expansion modules connect to the controller through an RS-485 E-bus network, allowing for installation up to 1220 meters (4000 feet) from the controller. Key features of this module include activation status LEDs for each relay, a communication failure LED with an alert output, a 24-hour anti-tamper input, and supply monitoring. Optional removable terminals are also available.
