OMRON H8PR-8 – Programmable 8-Point Output Relay | H8PR Series
Engineering Background
The OMRON H8PR-8 is a high-density programmable output relay module engineered for precision timing and sequential control in industrial automation environments. Developed under OMRON’s H8PR Series platform, this module delivers deterministic output switching across 8 independent relay points, making it a trusted component in machine builders’ control cabinets worldwide.
Product Positioning
Designed for procurement engineers and system integrators who require a compact, DIN-rail-mountable relay solution with programmable timing logic, the H8PR-8 eliminates the need for external timer modules by consolidating multi-point output control into a single, standardized form factor. It is the preferred choice for OEM panel builders, process automation upgrades, and legacy PLC I/O expansion projects.

Engineering Advantages
- 8 independent programmable output points in a compact single-module footprint
- Eliminates external discrete timer wiring — reduces panel complexity and commissioning time
- DIN-rail mounting ensures fast installation and standardized panel layout
- OMRON’s proven relay contact technology delivers high switching reliability and long mechanical life
- Compatible with standard 24 VDC control circuits common in modern PLC architectures
- Simplified programming interface reduces engineering hours during system integration
System Architecture & Signal Flow
The H8PR-8 interfaces directly with PLC digital output cards or standalone control circuits. Each of the 8 relay output points can be individually programmed for on-delay, off-delay, or sequential timing patterns. The module accepts standard control voltage inputs and provides isolated relay contacts for load switching, ensuring clean signal separation between control and power circuits. This architecture supports both normally-open (NO) and normally-closed (NC) wiring configurations.
