Pin Location Diagram- Models with External Accelerometer and Electromechanical Relays
When the external 100mV/g ICP
® Sensor option is specified, an additional terminal block location is added to the
685B-Series. The external accelerometer is connected to +Sensor and
–Sensor positions as indicated in the
above figure and on the product label locate inside the top cover. The cable shield to the accelerometer should be
grounded as required by local codes as well as to limit RFI/EMI interference.
