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 6DR5120-0NN00-0AA0 is a Sipart PS2 smart electropneumatic positioner engineered for precise control of pneumatic linear and part-turn actuators. This device operates as a 2-wire system with a 4-20mA input signal and includes an integrated HART interface for advanced configuration and diagnostics. Designed for double-acting actuators, it is housed in a durable polycarbonate enclosure and is intended for use in non-hazardous industrial areas (without explosion protection). The unit features 1/2" NPT electrical and 1/4" NPT pneumatic connections, and follows a standard fail-safe configuration where the actuator is depressurized upon loss of electrical power.
