Electrical & Physical Specifications

Deterministic Safety Bus & Firmware Flash Compatibility

The advanced architecture of the unit utilizes internal dual microcontrollers to continuously execute cross-monitored diagnostics across safety inputs and output control circuits. Integrated preset logic algorithms manage internal state transitions, coordinating synchronous communication via logical AND connections across connected Expansion Units. Internal processing logic maintains deterministic execution response cycles below 15 ms, isolating safety functions from external network latency. Flash memory components enforce strict firmware consistency checks during power-up boot routines, blocking hardware execution if internal self-test routines fail or voltage fluctuations breach operating thresholds.

Panel Wiring & Installation Directives

Mounting and Enclosure Setup

• Install the housing on standard 35-mm DIN rail inside a protective panel enclosure rated at minimum IP54 to prevent dust and moisture ingress.
• Maintain at least 50 mm clearance above and below the module housing for natural convection airflow and cable management.

Wiring and Signal Connections

• Use stranded copper wiring rated for 60 deg C or 75 deg C; strip insulation back 8 mm to 9 mm before inserting directly into spring-cage terminals.
• Insert a flat-blade screwdriver (0.6 mm x 3.5 mm blade) into the rectangular unlock slot to release terminal clamp tension during wire extraction.
• Route safety input cabling separately from high-voltage AC lines and VFD power cables to suppress inductive noise coupling.
• Connect a 24 VDC class 2 power supply source with functional grounding to ensure transient surge suppression and isolation compliance.

Frequently Asked Questions

• How are the OFF-delay times set on this unit?

  The OFF-delay timer is configured using the rotary switches located behind the front protective cover, allowing preset incremental adjustments up to 150 s.

• What load currents are supported by the safety outputs?

  When using two or fewer safety outputs, each output handles up to 1.0 A DC. When three or more outputs operate simultaneously, the limit is 0.8 A DC per channel.

• What is the response time when a safety input is opened?

  The instantaneous safety outputs turn OFF within 15 ms maximum after a valid safety input signal interruption is recognized by internal logic.

• How do the spring-cage terminals handle mechanical vibration?

  Spring-cage terminals exert continuous mechanical clamping force on conductors, resisting vibration shifts from 10 to 55 Hz without requiring periodic screw retightening.

• Does the auxiliary output provide safety-rated shut-off capabilities?

  No, auxiliary outputs are non-safety PNP transistor channels intended exclusively for status monitoring, diagnostic feedback, and PLC signaling.

• Can this unit expand its number of safety outputs?

  Yes, logical AND connections on the side connector allow direct linking to G9SX Expansion Units without requiring external hardwiring between safety logic terminals.

• What supply voltage limits must be maintained during operation?

  The unit requires a 24 VDC supply with an allowable operating range between 20.4 VDC and 26.4 VDC (-15% to +10% of rated voltage).

• What indicates an internal component or cross-short fault?

  The front-panel ERR LED lights or blinks in specific flashing sequences to indicate wiring shorts, power supply anomalies, or internal microprocessor fault conditions.
