The CMCP300B Four Channel Passive Buffer Module can accept four 2 or 3 wire sensors and can provide power to various accelerometers, proximity probes and speed sensors. Each channel can be independently configured to allow the use of 2 or more different sensors. Selectable constant current power is provided for all IEPE style accelerometers and dual power supply connections allow for +24V and -24V to be used simultaneously to power different sensor types. Passive Buffered Outptus are then provided via BNC, for portable instruments, and terminal blocks for hardwired systems. A total of 3 outputs are provided per input signal.
