## Summary description

Delta PK1-5-ZN is a relay module from Delta featuring a single-channel normally open (NO) relay configuration. Designed for control and switching applications, it provides galvanic isolation between control input and switched circuit and is suitable for industrial automation, control panels, and signal routing. Use it to switch loads, control actuators, or integrate into PLC and relay logic systems.

## Long description

Delta PK1-5-ZN is a single-channel normally open relay module designed for control and switching applications. The module provides a dedicated NO contact that closes when the relay is energized, allowing safe switching of circuits while keeping the control input galvanically isolated from the switched load. Intended for integration in industrial automation, control panels, PLC systems and signal routing tasks, the relay module offers a compact, straightforward solution for controlling actuators, lamps, small motors or other loads compatible with its contact ratings.
Advantages
The relay module delivers galvanic isolation between the control input and the switched circuit, reducing interference and improving safety. Its single-channel normally open configuration simplifies wiring and logic design where a normally open contact is required. The compact form factor and standard mounting and terminal connections make it convenient to install in control cabinets and on DIN rails or panels. The module is manufactured by Delta, ensuring consistent production quality and compatibility with typical industrial control environments.
Suitable for
Switching actuators and solenoids in automation systems
Controlling indicator lamps and signal circuits
Integration into PLC and relay logic panels
Small motor control and load switching within contact ratings
Signal routing and isolation between control and power circuits
Key specifications
Configuration: single-channel, normally open (NO) contact
Isolation: galvanic isolation between control input and switched circuit
Intended use: control and switching in industrial automation and control panels
Mounting: compact module suitable for panel or DIN-rail mounting (depending on panel design)
Connection: standard screw terminal or equivalent industrial connection for signal and load wiring
How to use
Mount the relay module securely within a control cabinet or on an appropriate mounting rail and connect the control input to the designated coil/input terminals, observing the correct control voltage and polarity if required. Wire the load circuit to the normally open contact terminals, ensuring that the load current and voltage do not exceed the relay contact ratings. After wiring, apply the control signal to energize the relay; the NO contact will close and allow current to flow to the switched load while maintaining galvanic separation between the control and load circuits.
Usage recommendations
Verify the contact load ratings and insulation requirements before installation; use appropriate overcurrent protection and suppression components when switching inductive loads. Ensure wiring and grounding meet local electrical codes and manufacturer guidelines to maintain isolation and reduce electrical noise. For long-term reliability, operate the module within specified environmental conditions and perform periodic inspections of terminal tightness and contact condition.
