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 ABB 3BSE024388R1 PFXA 401 is a control unit used in ABB force measurement, strip tension, and strip position measurement systems.
The PFXA 401 provides two analog inputs and supports angle compensation for compatible ABB load cells. ABB documents compatibility with QGPR 102/104 load cells up to 2 MN and PFBL 101/141 load cells up to 2 x 400 kN.
The control unit can also interface with two PMSG 123 or PMSG 125 edge sensors. This allows the PFXA 401 to participate in strip width and position measurement applications as well as force and tension measurement systems.
The unit incorporates dedicated mains, synchronization, analog output, digital signal, and sensor connection terminals. Its ABB product record also identifies an internal lithium battery and a 2 A, 250 V fuse.
