Flexible Safety Unit
G9SX
Logical AND Function Adds Flexibility
to I/O Expansion
• Facilitates partial or complete control system setup.
• Solid-state outputs (excluding Expansion Units).
• Detailed LED indications enable easy diagnosis.
• TÜV Product Service certification for compliance
with IEC/EN61508 (SIL3) and EN954-1 (Cat. 4).
• Approved by UL and CSA.
• New unit joins the Series with the following
two additional features:
-OFF-delay time of up to 150 seconds
(The OFF-delay output also complies with Cat. 4.)
-Two logical AND connection inputs
Note: Refer to Precautions on pages 17 and 18.
Features
● Productivity
"Partial stop" and "Complete stop" enhance productivity without sacrificing safety.
● Maintenance
LED indicators and detachable terminals for better maintenance.
● Expandability
"Logical connection" enables easier modification and expansion of machines.
Ex) Machining Center
• When the Emergency Stop Switch is pressed, the entire machine will stop.
• When a door is open, the corresponding part will not activate.

  • Page 11 ■ Connecting Safety Sensors and the G9SX 1. When connecting safety sensors to the G9SX, the Y1 terminal must be connected to 24 VDC. The G9SX will detect a connection error, if the Y1 terminal is open. 2. In many cases, safety sensor outputs include an OFF-shot pulse for self diagnosis.
  • Page 12 Basic Unit) Set the cross fault detection mode for safety inputs by shorting Y1 to 24 V or leaving it open. When cross fault detection is set to ON, short-circuit failures are detected between safety inputs T11-T12 and T21-22. When a cross fault is detected, the following will occur.
  • Page 13 Advanced Unit C The OFF-delay preset time on an Advanced Unit is set from the OFF- delay time preset switch (1 each on the front and back of the Unit). Normal operation will only occur if both switches are identically set.
