4.4 Setting up a Typical ER3000 Pressure Control System

One of the most commonly used modes of operation is shown in Figure 3. The

configuration shows the ER3000 with a 24 Volt power supply, pressure

regulator, 4-20mA transducer, RS232/RS485 converter, and an optional 25-9 pin

adapter cable. Note: For USB-RS485 converter, see instructions included with

converter.

If higher pressures or flows are required by the application or it is necessary to

isolate the controller from the process media, an air actuated mechanical

regulator can be used to boost the output and/or provide isolation.

Additionally, an external transducer may be used to sense the process pressure

supplied by the external regulator.
