Part 2

Plug-In Assembly Configuration 469This example shows a configuration in which load voltage E is switchedfrom load #I to load #2 when the relay in that channel is closed (E doesnot have to have the same value for both loads).When the relay is open, the NC contact is connected to COMMON andwhen the relay is closed, the NO contact is connected to COMMON. If contactprotection is required, it should be connected across both the NO andNC contacts, as close to the relay as possible.CHANNELKOiINORMAL - OPEh- 3497-OPC-38uCONTACTPROTECTION100VA MAX@ 1A MAX* CAUTIONFOR LOADS >12V OR CURRENT >65mA,CONTACT PROTECTION NAY BE REOUIREOPreviously, we noted that the assembly could be wired as a 4 X 4 matrixswitch to switch source inputs to measuring instruments. This exampleshows a setup in which the common terminals of relays KO-K3 are connectedto I1 common, etc., and the NO contacts of relays KO, K4, K8 andK12 are connected together, etc.To connect any source to any instrument, merely send DC slot#,chan# toclose the appropriate relay. For example, to connect source S2 to instrument13, send DC slot#,9 to close Kg.p p q LsqN.D. N.O. N.O. N ~ O .K4 1 N.O. 4 K5 / N.O.Artisan Technology Group - Quality Instrumentation ...
