Wiring

 

Wiring to the Series 9215 operator interface  can be done using 232 or 485 to two connectors, comm1 (232) or comm3 (485).  The terminal strip on the lower right rear corner of the operator interface is used to connect 24VDC power. The DB-9 port A connection is used to connect the display via 232 to the Series 9215 PID controller. The controller is connected via RS485 communication to the single-loop controllers.
