Differential Charge Input for Bridge Module

Front panel UA-3121-030 is for use with LAN-XI Bridge Module Type 3057. The front panel has three input channels with buffered monitor output channels in parallel. Each input channel has a 15-pin D-sub connector for bridge transducer input and two Microdot connectors for differential charge input. The 15-pin D-sub connectors allow individual configurations of completion resistors to be made directly on the cable plug. 

UA-3121-030 and UA-3122-030 are very similar. UA-3121-030 has connectors for differential charge input and UA-3122-030 has connectors for direct or CCLD input. 

Note: Only one kind of input per channel can be used at a time.
