Inputs

Figure 1. Dual Output Switch Box Layout

• Dual Outputs for Temperature and Vibration
BNC J1 & 2 pin output – Dynamic Vibration

BNC J2 – Temperature (in Volts DC)

• Dual Outputs for Loop Power and Vibration (typically not used in this

application)

BNC J1 & 2 pin output – Dynamic Vibration
BNC J2 – 4-20mA output

• Requires optional JB905-1A Block to provide power from PLC/DCS

system and to LP series sensor.
