Product Overview
The G7SA-5A1B DC24V is part of Omron safety relay solutions designed for emergency stop, guard monitoring, and safety interlock systems. Force-guided contacts support diagnostic integrity in safety-related control circuits.
Force-Guided Contact Principle
Mechanical linkage between contacts helps detect certain welded-contact failures, supporting safer feedback and monitoring strategies in compliant safety designs.
24VDC Coil for Standard Safety Control Panels
The DC24V coil aligns with common machine safety supply architectures, reducing integration friction in new or retrofit builds.
Application Scope
Used as part of layered safety logic with safety relays/controllers, contactors, and monitored feedback loops to manage hazardous motion and energy states.

FAQ for G7SA-5A1B DC24V
Is this the same as G7SA-5A1B DC24?
Yes, DC24 and DC24V refer to the same 24VDC coil voltage. Different listings may use either notation.
When do I need 5NO contacts?
5NO contacts for complex safety systems controlling: main contactor, brake relay, hydraulic valve, pneumatic valve, alarm indicator, and feedback monitoring. Multiple safety outputs from single relay.
What's the maximum switching current?
5A at 250VAC resistive, 3A at 250VAC inductive (AC-15). For higher currents, use relay contacts to control contactors rather than switching load directly.
How do I test the safety function?
Regular testing per machine safety requirements: activate safety device (E-stop, gate switch), verify machine stops within required time, verify NC contact opens, document test results.
