Comprehensive G7SA-5A1B DC24 Specification Analysis
Understanding the detailed specification is crucial for proper application. This Omron relay operates with a nominal coil voltage of 24VDC, making it compatible with standard control voltage supplies found in modern automation systems. The contact configuration offers flexibility with five normally open (NO) contacts and one normally closed (NC) contact, all forcibly guided according to EN 61810-3.
These contacts are rated for a switching current of 6 A at 250 VAC or 30 VDC (resistive load), providing sufficient capacity for various control tasks. The slim design is a significant advantage in crowded control cabinets, optimizing space while delivering robust performance. Its compliance with international safety standards underscores its suitability for critical applications where failure is not an option.
The Core of Safety: Forcibly Guided Contacts Explained
The defining feature of the G7SA-5A1B DC24 is its forcibly guided contact mechanism. This is a fundamental requirement for any genuine safety relay. In simple terms, if one contact welds shut (fails closed), the corresponding linked contact is mechanically prevented from closing when the coil is de-energized. This ensures that a failure state can be reliably detected by the safety monitoring circuit, often managed by a safety PLC.
This mechanism is critical in applications like emergency stops, light curtains, and safety interlocks. The G7SA-5A1B DC24 provides this high level of safety assurance, helping you build systems compliant with standards like ISO 13849-1 and IEC 62061. Trusting Omron’s expertise in safety components means building inherently safer machines.
Seamless Integration: Mounting and Connectivity
Designed for efficiency, the G7SA-5A1B relay facilitates easy mounting onto standard 35mm DIN rails. This allows for quick installation and replacement within control panels, minimizing downtime. The relay itself plugs into dedicated sockets, such as the P7SA series socket, which provide the actual wiring terminals.
These sockets are available with different terminal types, including user-friendly Push-In Plus terminals for rapid, tool-less wiring or traditional screw terminals for robust connections. This flexibility ensures compatibility with various panel building practices and preferences. The clear polarity markings (+A1, -A2) for the 24 VDC coil further simplify wiring and prevent connection errors during installation.
Reliable Performance: Contact Configuration (5PST-NO SPST-NC)
The G7SA-5A1B DC24 features a specific contact arrangement: 5 Pole Single Throw – Normally Open (5PST-NO) and 1 Pole Single Throw – Normally Closed (SPST-NC). This configuration is common in safety applications, allowing multiple circuits to be safely switched ON while providing a feedback signal (via the NC contact) to the monitoring system about the relay’s state.
The reliability of these contacts is paramount. Omron utilizes high-quality materials and construction techniques to ensure long electrical and mechanical endurance, even in challenging industrial environments. This robust design contributes to the overall reliability and longevity of your safety control system, reducing maintenance needs and ensuring consistent safety protection.

Frequently Asked Questions
You need an Omron P7SA series socket compatible with the G7SA relay family. Options include screw terminals (e.g., P7SA-10F-ND-PU) or Push-In Plus terminals (e.g., P7SA-10P-PU).
Yes, the G7SA-5A1B DC24, when used correctly within a properly designed safety circuit (often involving dual channels and monitoring by a safety controller), can be part of systems achieving up to Safety Category 4 / PLe according to ISO 13849-1. Always refer to the official documentation and perform a risk assessment.
The mechanical endurance is typically rated for millions of operations, while the electrical endurance depends heavily on the load being switched. Datasheets provide detailed endurance curves based on load conditions.
It’s widely used in emergency stop circuits, safety gate monitoring, light curtain controls, two-hand control systems, and other safety-related functions in industrial machinery and automation.
