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.
The Honeywell 10106/2/1 is a 16-channel fail-safe digital input module for Honeywell FSC systems. It is designed for 24/48 VDC NAMUR field inputs with line monitoring and earth-fault supervision.
The module uses NAMUR input characteristics and monitors field circuits rather than only reading ON/OFF states. This makes the 10106/2/1 suitable where input wiring faults must be distinguished from normal process status. Honeywell FSC documentation identifies it as a fail-safe line-monitored digital input module with earth fault monitor.
