12-1. Preface

Feasible combinations of the SC202G conductivity transmitters with different styles of the PH201G dis-
tributor are listed in the table below. The distributor has the usual distributor functions (supply power to
transmitter, receive current output from transmitter, and provide analog output) as well as contact output
functions (maintenance, wash and fail status signals). Since the two transmitters provide different digital
signals to control the distributor contact outputs, two distributor styles are provided for compatibility. The
SC202G is not intrinsically safe (explosionproof), so never install it in a hazardous area.
