## Summary description

Delta PK4-24-ZD is a relay module with four normally open (NO) outputs and 24 V DC control. Designed for use in automation panels and control circuits, it enables switching of loads via relay contacts. Suitable for industrial control, signal isolation, and interfacing low-voltage control systems with external devices requiring relay switching.

## Long description

Delta PK4-24-ZD is a relay module with four normally open (NO) outputs and 24 V DC control, intended for installation in automation panels and control cabinets. The module provides galvanic isolation between control circuits and switched loads, enabling reliable switching of external devices and signal routing in industrial control systems. Its compact design allows space-efficient integration into existing control architectures where low-voltage control must operate higher-power or isolated circuits.
Advantages
The module offers four independent NO relay channels operated from a 24 V DC control input, simplifying wiring and panel layout. Its design emphasizes electrical isolation between input and output, reducing interference and protecting sensitive control electronics. Standard terminal connections and a compact footprint ease mounting and replacement in commercial and industrial installations. The device supports common relay functions such as on/off switching and signal routing without requiring additional interface circuitry.
Suitable for
Interfacing PLCs, controllers or sensors with external actuators and loads
Signal isolation and noise separation in control panels
Switching lighting, small motors, solenoids, or indicator circuits controlled from 24 V DC
Retrofit and maintenance tasks requiring modular relay outputs
Key specifications
Number of outputs: 4 normally open (NO) relay contacts
Control voltage: 24 V DC input for coil activation
Function: Mechanical relay switching for isolation between control and load circuits
Mounting: Panel or DIN-rail compatible compact module form factor
Terminal type: Screw or plug-in terminals suitable for standard control wiring
How to use
Install the relay module in a control panel or on a DIN rail according to panel layout and safety rules. Connect the 24 V DC control supply to the designated input terminals and wire the switched loads to the NO output contacts, observing correct polarity and load ratings. Use appropriate wire sizes and secure terminal connections to maintain reliable operation. Verify wiring and insulation before powering the system and test each channel by applying the control voltage to confirm switching behavior and contact operation.
Usage recommendations
Ensure that connected loads do not exceed the relay contact current and voltage ratings; provide external protection such as fuses or circuit breakers where necessary. For inductive loads, add suppression components (diodes, RC snubbers or varistors) to protect contacts and reduce electromagnetic interference. Maintain regular inspection of terminal tightness and contact condition in environments with vibration or high duty cycles.
