Configured for safety input evaluation and OFF-delayed power cutoff execution in industrial machine control loops, the Omron G9SX-ADA222-T15-RT (G9SX-ADA222 Flexible Safety Unit) provides direct physical/electrical execution.

Part Number Nomenclature & Configuration

• G9SX: Omron standalone and expandable modular safety relay controller line.

• ADA: Advanced Unit platform supporting logical AND expansion inputs and preset delay logic.

• 2: Instantaneous safety outputs (2 P-channel MOS FET semiconductor channels).

• 2: OFF-delayed safety outputs (2 P-channel MOS FET semiconductor channels).

• 2: Auxiliary outputs (2 PNP transistor non-safety monitoring channels).

• T15: Maximum adjustable OFF-delay duration up to 15 s.

• RT: Screw terminal connection block layout with pluggable terminal housing.

Technical & Electrical Parameters

Deterministic Safety Logic Execution & Firmware Flash Verification

Dual internal microprocessors execute continuous cross-channel comparison routines and fault detection algorithms every operating cycle. Internal switching matrices process signals from safety inputs and AND-connection expansion buses to guarantee deterministic response states within 15 ms of signal de-energization. Integrated firmware flash routines validate hardware register states during startup power-on self-tests; any voltage sag below 20.4 VDC or cross-short detection halts output execution immediately to enforce a safe state.

Field Wiring & Panel Mounting Directives

Mounting Specifications

• Snap module onto standard 35-mm DIN rail in a dust-protected NEMA 12 or IP54 control cabinet.

• Ensure a minimum clearance distance of 50 mm above and below the housing for heat convection and conductor routing.

Electrical Wiring Controls

• Strip wire ends 7 mm to 8 mm; tighten M3 terminal screws to a torque spec of 0.5 N-m to 0.6 N-m.

• Separate safety input wiring from AC motor leads and switched inductive loads to eliminate electromagnetic interference.

• Supply logic circuits with a regulated 24 VDC PELV/SELV power supply unit featuring surge suppression.

Frequently Asked Questions

• What is the response latency when a safety input circuit opens?

  The instantaneous P-channel MOS FET safety outputs switch off within a maximum response delay of 15 ms following input circuit interruption.

• How are the OFF-delay times configured on this module?

  Rotary switches located on the front panel beneath the protective door adjust the OFF-delay timing incrementally up to 15 s.

• What load current limits apply when all four safety outputs are active?

  When utilizing three or more safety outputs simultaneously, maximum load current is capped at 0.8 A DC per output channel.

• What is the function of the PNP auxiliary outputs?

  Auxiliary outputs provide 100 mA non-safety status signals to standard PLCs or pilot lights for system diagnostics.

• Does the unit support expansion to add more safety outputs?

  Yes, side-mounted logical AND connectors enable direct wiring-free connection to G9SX series Expansion Units.

• What terminal type is designated by the RT suffix?

  The RT designation specifies M3 screw terminals housed within pluggable terminal blocks for quick replacement.

• What input voltage range maintains valid safety operation?

  The module operates reliably across a DC supply voltage window of 20.4 VDC to 26.4 VDC (-15% to +10% tolerance).

• How does the system signal cross-short or terminal fault conditions?

  The red ERR indicator illuminates or flashes coded sequences on the front display to identify specific internal or external fault conditions.
