Implementing 3-Switch XOR Ladder Logic with Internal Bit
Implement a 3-SPST switch XOR light circuit in LogixPro or RSLogix 500 using an internal relay bit. Includes truth tables, boolean equations, and verified.
Integrating directly into master safety architectures, the Omron G9SX-EX401-RT expansion module expands the output capabilities of standard safety systems by providing additional instantaneous relay channels. Operating on a 24 VDC supply, this unit features 4 instantaneous safety outputs and 1 auxiliary feedback output, allowing industrial automation systems to scale safety-related control circuits without compromising response speed or diagnostic visibility. Designed with robust screw terminals, it ensures high vibration resistance and secure wiring connections in demanding industrial environments.
| Parameter | Specification Value |
|---|---|
| Manufacturer | Omron |
| Model Code | G9SX-EX401-RT |
| Series | G9SX Series |
| Device Type | Flexible Safety Expansion Unit |
| Rated Supply Voltage | 24 VDC |
| Operating Voltage Range | -15% to 10% of rated supply voltage |
| Rated Power Consumption | 2 W maximum |
| Safety Relay Outputs | 4 instantaneous outputs (DPST-NO x 2) |
| Auxiliary Outputs | 1 auxiliary semiconductor output |
| Rated Load | 250 VAC, 3 A / 30 VDC, 3 A (resistive load) |
| Rated Carry Current | 3 A |
| Operating Time (OFF to ON) | 30 ms maximum |
| Response Time (ON to OFF) | 10 ms maximum |
| Mechanical Durability | 5,000,000 cycles minimum (switching frequency: 7,200 cycles/hour) |
| Electrical Durability | 100,000 cycles minimum (rated load, switching frequency: 1,800 cycles/hour) |
| Terminal Type | Screw terminals |
| Product Net Weight | 0.165 kg |
| Shipping Weight (Calculated) | 1.50 kg |
This expansion unit must always be matched with a master G9SX unit (e.g., G9SX-AD or G9SX-ADA series). It cannot operate as a standalone safety relay. When replacing older Omron safety expansion modules, verify terminal footprints; the RT model features screw terminals, which differ from spring-cage (RC) variants.
When calculating the safety integrity level (SIL) and performance level (PL) for your safety loop, remember to add the 10 ms maximum response time of the expansion unit to the response time of your master G9SX unit. Ignoring this cumulative propagation delay can lead to insufficient safety distances for light curtains and emergency stop stations.
Ensure that the cross-unit connection cable is fully locked into place on both sides before applying 24 VDC control power. Powering the system up with a loose or partially inserted communication bus connector will cause the master module to enter a critical system fault mode, requiring a full power cycle to reset.
