DSC RL4-LC Quad Form "C" 4-Relay Board Module, Low Current

Streamline control of multiple security devices with the DSC RL4-LC Quad Relay Board Module. This DSC relay board delivers four independent Form C contacts in a compact, low-current package so you can trigger alarms, door locks, CCTV inputs and other peripherals without overloading your panel. The RL4-LC supports selectable positive or negative activation via a convenient jumper, making integration with diverse alarm and access control panels fast and foolproof. Low-current operation reduces overall system power draw and extends the life of connected outputs, while hybrid installation options let technicians mount the module inside enclosures or retrofit into existing racks and panels. Built by Johnson Controls for intrusion sector applications, the RL4-LC is ideal for security integrators who need dependable relay switching for surveillance, monitoring and access control projects. Add predictable, isolated switching to your designs—use the RL4-LC for alarm-triggered camera presets, door release control, zone annunciation or automation tasks.
