Wiring
Wiring to the Series 9205 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 9205
PID controller. The controller is connected via RS485 communication to the single-loop controllers.
Electrical Installation
The Model 9205 requires 24VDC, 4 Watt, single-phase power. A 24 VDC power supply is required
and is generally included as part of the Model 9205 system. This power supply has a universal
input that can accept between 60 and 265VAC. Power should be applied in accordance with the
electrical drawings that have been supplied. Since each installation is unique to the site, the
customer is responsible for providing adequate power and making it available to the Model 9205
power supply.
