DSC PC4204CX Power Supply/ 4-Relay Output/Combus Repeater Module

Ensure uninterrupted operation and greater system reach with the DSC PC4204CX Power Supply/Relay Output/Combus Repeater Module. Purpose-built for MAXSYS intrusion installations, this module delivers supervised 12.5V DC power to connected devices while regenerating the Combus data signal to enable longer cable runs and larger site coverage. Four programmable Form C relays (rated 2A at 30V DC) give you on-board control for locks, strobes, relays or other auxiliary equipment, reducing the need for additional hardware.

Engineered for reliability in security, surveillance and access control applications, the PC4204CX is fully supervised for AC failure, low battery and AUX faults, simplifying integration with control panels and monitoring stations. Installers benefit from scalable design — up to 16 modules can be deployed to match system growth without compromising performance. Ideal for commercial buildings, multi-site monitoring, and complex security topologies.

Boost system resiliency and simplify deployment on your next project — add the DSC PC4204CX to your MAXSYS lineup to extend Combus range, provide dependable power and enhance monitoring capability. Contact sales or order today.
