Specifications Of Digital Input (Di) Circuits - FATEK FBS Series Manual

Chapter 6
The FB -PLC provides the ultra high speed differential double end 5VDC inputs (i.e., single input with two terminals
S
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 (we will use the term SRCE) for
input or in differential input wiring for line driver source. The single-end input circuit can be set to SINK or SRCE 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).

： The standard product of MC-type High-Speed input is 2 points, it can extend to 3~8points (Option). Every increment one High-speed
input point, and decrement one Middle-speed input point relatively. Only X4~X5,X8~X9 and X12~X13 input can be extended, and
the priority is low serial-number to High serial-number.
