## Summary description

Delta PK1-5-ZS is a relay module designed to provide a single normally open (NO) switching contact for electrical control applications. As a compact plug-in module from Delta, it is intended for use in control panels, automation systems and signal switching tasks where an isolated mechanical contact is required to switch circuits or loads. Suitable for replacing or expanding relay outputs in industrial and building automation setups.

## Long description

Delta PK1-5-ZS is a compact single-channel relay module offering one normally open (NO) mechanical contact for switching electrical circuits. Designed as a plug-in module, it provides isolated switching suitable for control panels, industrial automation and building management systems. The module is intended to replace or expand relay outputs where a dedicated NO contact is required for control of loads, signaling or interlocking functions.
Advantages
The relay module delivers a clear electrical separation between coil and contact circuits, enabling safe switching of external loads without direct electrical coupling. Its compact plug-in form factor simplifies installation and replacement in relay sockets or DIN-rail mounted interface blocks. As a single normally open contact, the PK1-5-ZS reduces complexity where a simple make-only switching element is needed, and its rugged mechanical contact ensures repeatable performance in typical control environments.
Suitable for
Replacing or expanding relay outputs in PLC and control cabinets
Signal switching and interlocking in industrial automation
Control of non-critical loads such as indicator circuits and small actuators
Integration into building management and alarm systems
Key specifications
Contact configuration: single normally open (NO) mechanical contact
Module type: plug-in relay module designed for socket or interface block mounting
Isolation: galvanically isolated contact and coil circuits for safe switching
Typical applications: control panel switching, signal routing, interlocking
Form factor: compact single-channel module suitable for tight panel layouts
How to use
Install the Delta PK1-5-ZS into a compatible relay socket or interface block according to panel wiring diagrams. Connect the coil to the control output that provides the appropriate drive signal and wire the NO contact in series with the load or signaling circuit to be switched. Verify proper contact ratings and wiring polarity where applicable, and ensure the module is secured and protected from excessive vibration and moisture. Test operation by energizing the coil and confirming that the normally open contact closes to allow current through the switched circuit.
Usage recommendations
Use the relay module within the rated voltage and current limits of the circuits it will switch. For long-term reliability, avoid exposing the module to corrosive atmospheres and excessive mechanical shock. When integrating into safety-related systems, follow applicable standards and implement appropriate monitoring or redundancy if a single NO contact is used for critical functions.
