The signal input modules connect the field instrumentation to the machinery health processor.
Each signal input module can input up to 12 vibration signal inputs, 2 tachometer inputs and has 2 relay inputs for event-based vibration monitoring control and/or outputs for alarm enunciation. Up to two A6510 signal input modules can be associated with a machinery health processor. The A6560 and A6560-T processors work in conjunction with the signal input modules, the A6510 and A6510-T, respectively.
