Physical & Electrical Performance Data

Deterministic Internal Bus & Signal Isolation Architecture

The module utilizes dedicated side-connector backplane bus communication velocity to link directly with master safety controllers, maintaining execution synchronism without relying on external network protocols like EtherNet/IP or Profinet. Channel-to-channel internal galvanic isolation shields control electronics from field contact transients. Firmware flash compatibility across the G9SX platform guarantees fixed safety loop timing, maintaining strict compliance during deterministic safety trip sequences.

Package & Supply List

• 1 x Omron G9SX-EX041-T-RT Flexible Safety Expansion Block

• 1 x Factory-Mounted Screw Terminal Block Assembly

• 1 x Technical Installation Instruction Leaflet

Field Installation & Wiring Directives

• DIN-Rail Mounting Mount the unit vertically onto a standard 35-mm DIN rail within an enclosure offering at least IP54 ingress protection. Ensure 50-mm vertical clearance above and below for natural thermal dissipation.

• Terminal & Cable Routing Utilize copper conductors rated for 60/75 deg C. Tighten all screw terminal connectors to a torque specification between 0.5 and 0.6 N.m to prevent loose contact arcing.

• Electrical Separation Route safety signal lines away from heavy AC power cables and variable frequency drive motor leads to prevent electromagnetic interference.

Technical Inquiries & Operational FAQ

• What is the principal output configuration of the G9SX-EX041-T-RT?

  It provides four OFF-delayed safety outputs and one auxiliary monitoring output, with zero instantaneous safety outputs built in.

• Does the G9SX-EX041-T-RT function as a standalone controller?

  No, this expansion unit must be connected to a G9SX master unit via the dedicated internal side connector to operate properly.

• What voltage supply is required for operation?

  The unit operates on 24 VDC with an allowable operating voltage range from -15% to 10% of the rated supply voltage.

• How fast is the ON-to-OFF response time when triggered?

  The unit features a maximum ON-to-OFF response time of 10 ms, excluding any pre-configured internal OFF-delay time setting.

• What type of wiring connections are provided on the -RT variant?

  The -RT designation indicates that the unit is equipped with removable screw terminal blocks for field conductor connections.

• What is the electrical switching capacity of the safety contacts?

  The contacts handle a rated load of 250 VAC at 3 A or 30 VDC at 3 A under standard resistive load switching conditions.

• Can this unit be hot-swapped while the system is powered?

  No, main control power must be completely disconnected before attaching or removing expansion modules from the backplane bus.

• What is the rated power consumption of the module?

  The internal circuitry and output coils consume a maximum power rating of 2 W under full 24 VDC load conditions.
