KCD2-SR-EX2 safety barrier DIP switch settings

Thread Content

The wiring diagram for KCD2-SR-EX2 is as follows: terminals 1 and 2 represent the first set of inputs, corresponding to outputs at terminals 5 and 6； Terminals 3 and 4 are the second set of inputs, corresponding to terminals 7 and 8 as outputs. The two sets of signals are independent. S1/S2 correspond to the normally open and normally closed settings for the two groups of signals, respectively. For example, if S1=I, then when 1 and 2 are normally open, 5 and 6 output normally open ； If S1=II, then when 1 and 2 are normally open, 5 and 6 output normally closed. If S2=I, then when 3 and 4 are normally open, 7 and 8 output normally open ； If S2=II, then when 3 and 4 are normally open, 7 and 8 output normally closed. S3/S4 also correspond to two sets of signals respectively. For example, if S3=I, the 1 and 2 inputs should be connected to intrinsically safe input signals (NAMUR) ； If S3=II, then the 1 and 2 inputs should be connected to normally open contact input signals. If S4=I, the 3 and 4 inputs should be connected to intrinsically safe input signals (NAMUR) ； If S4=II, then the 3 and 4 inputs should be connected to normally open contact input signals.
