Power and the Analog input terminal with the 4 20ma jumper removed As always the wiring to analog sensors should be kept away from other switching and power lines to ensure good analog accuracy The Digital Inputs are powered such that a connection made through a field dry contact closure between the DI terminal and one of the RET terminals will cause the corresponding LED to light and activate the logical input signal The inputs are powered by 24VDC and must not be connected to AC voltages of any value The Digital Outputs are relay contact closures with one side of each contact connected to a common conductor These outputs are rated for voltages not to exceed 230VAC and intended to operate 8 Watt or smaller loads for the maximum relay contact life Each relay output is a Normally Open contact a Normally Closed type contact is not available The common conductor is fused PCM100 Summary of Connections The following tables define the function of each of the PCM100 s connections Connectors TB1 Input Terminations 1 Al 1 2 Al 2 3 ATH3 4 Al 4 5 IRET 6 IRET 7 SVDC sensor power supply 40ma max 8 24VDC power 0 25A max 9 DH 10 DI 2 11 DI 3 12 DI 4 13 DI 5 14 DI 6 15 DI 7 16 DI 8 17 RET 18 RET TB2 Output Terminations 1 DO 1 NO relay contact common side to TB2 5 2 DOH2 NO relay contact common side to TB2 5 3 DO 3 NO relay contact common side to TB2 5 4
