Omron G9SX Series Safety Relay, 24V DC Coil Voltage, 3PST Contact Configuration - G9SX-AD322-T15-RT DC24


This safety relay is a Compact control device for machine safety circuits, designed to monitor dual safety inputs and govern both instantaneous and OFF‑delayed outputs in industrial automation systems. It operates from a 24V DC supply and is intended for PCB mounting in machinery control cabinets, providing selectable reset behaviour and logical AND interconnection for scalable I/O expansion.

Features & Benefits


• 24V DC Coil with 4W power draw for efficient operation
• Three safety contacts rated 3A to switch typical control loads
• OFF‑delay selectable up to 15s enabling timed shutdowns
• Automatic reset option for hands‑free recovery after fault clearance
• Logical AND inputs permit modular system expansion and partitioned control
• Screw Terminal Interface for secure PCB connection and field wiring

**Applications**


• Suitable for monitoring emergency‑stop circuits on production lines
• Ideal for integrating safety doors and guard interlocks on machines
• Used with contactors to control motor isolation and feedback loops
• Can be used for staged machine stopping where partial stops are required
• Suitable for expansion via additional units to increase safety outputs

What environmental range can I expect for reliable operation?


It functions across −10°C to +55°C ambient temperature with no icing or condensation allowed.

How does the unit signal diagnostic or fault conditions?


Multiple LEDs indicate power, input states, output status and specific error conditions while an auxiliary error output provides a remote fault signal.

What electrical switching limits apply to expansion relay outputs?


Expansion relay outputs are rated for resistive loads up to 250V AC/3A and 125V DC/3A with a maximum carry current of 3A.

How are logical AND connections scaled in multi‑unit systems?


One logical output can feed up to four subsequent units and systems may be configured up to 20 units total with a maximum of five tiers in series.

What wiring and installation precautions affect field use?


Terminals require 0.5 N·m tightening torque for screw types

safety inputs and logical links should use cables under 100m and the unit must be grounded at the negative supply terminal.
