In-puts are available to the Logic Master Module,Multi-Function Controller (MFC), or the Bailey PC-90Processor Module (MPC) on the 12-line Expander Bus(see Figure 2-1). The physical slave address is set with theaddress select switch s1.INPUTSField input voltages are contact closures of either 24 V dc,125Vdc,or 120 v acrms.The dc inputs have two possiblepropagation (speed) choices. A slow setting (18 mil-iisecondresponse time) and a fast setting (1.5 millisecondsresponse time).The voltage level and dc speed for eachinput is selected by on-board jumpers. The InstallationSection contains directions for connecting jumpers.
