model 624 has G1/2B or G1B flush diaphragm
connections. Refer to the catalog for complete
specifications. Do not torque the process connector
with a force greater than 37 foot pounds.
For the 4 mA to 20 mA output version, install
the power supply, transmitter and receiving
instrument in series to form a 2-wire current
loop. The transducer regulates the current in
the loop.

category II and the pollution degree 1. For the
voltage output version, the 3-wire system uses
separate leads for the power supply and output
signal. The 3rd lead is a common minus.
Use a NEC Class 02 power supply, low
voltage and low current maximum 100 VA even
under fault conditions.
