## Long description

ACO CDN-PK is a universal relay interface module designed to provide a standardized connection point for a jumper or coil within control, alarm and automation systems. The compact module facilitates signal switching and electrical isolation between circuits, allowing integration of external devices such as alarm panels, control units and actuators. Its design focuses on reliable relay operation where a simple, space-saving interface is required.
Advantages
The module offers a compact footprint and a clean, terminal-based connection layout that simplifies installation in cabinets or on DIN rails. It provides galvanic separation of relay contacts to reduce interference between control and output circuits. The device is compatible with a range of low-voltage control signals, enabling straightforward replacement or extension of relay functions without changing main control hardware.
Suitable for
Alarm and security panels requiring isolated relay contacts
Building automation systems for switching control signals
Industrial control where a compact relay interface is needed
Integration of external actuators, sirens or indicator devices
Key specifications
Function: single relay interface for jumper/coil connection
Contact type: changeover (SPDT) relay contacts for signal switching
Mounting: compact module suitable for panel or DIN-rail installation
Connections: screw terminals for secure wiring of input and output circuits
Electrical isolation: galvanic separation between control and switched circuits
Operating environment: intended for indoor use within control and alarm enclosures
How to use
Install the ACO CDN-PK module into the control cabinet or on a DIN rail and secure wiring to the screw terminals according to the system wiring diagram. Connect the control signal or jumper to the designated input terminal and the external device or coil to the relay output terminals. Ensure supply and control voltages match the system specifications and verify correct polarity where applicable. After wiring, perform a functional test to confirm the relay actuates and isolates circuits as intended.
Usage recommendations
Use the module within the rated control voltage range and in environments free from excessive moisture, dust or corrosive substances. For reliable operation, follow the system manufacturer’s wiring diagrams and verify contact ratings against the load to avoid overloading the relay contacts. If used in safety or alarm systems, perform periodic tests and maintenance in accordance with local regulations and installer guidelines.
