Chapter 6 Digital Input (DI) Circuit
The FBS-PLC provides the ultra high speed differential double end 5VDC inputs (i.e., single input with two terminals
without common) and the single-end 24VDC inputs which use the common terminal to save terminals. The response
speeds of single-end common input circuits are available in high, medium and low. Because the double end input
circuit has two independent terminals, it can be connected either in SINK or SOURCE for input or in differential input
wiring for line driver source. The single-end input circuit can be set to SINK or SOURCE type by varying the wiring of
the common terminals S/S inside PLC and external common wire of input circuits (see Sec. 6.3 for details).
