PRO-PRC

Quad Process Controller

This quad channel process controller is ideal for numerous industrial applications

with 0–20mA or 4–20mA DC inputs. It can be used either on its own, or inconjunc-

tion with another instrument (such as a transmitter).

One of the key features of this controller is its ability to average the inputs across 2,

3 or 4 input channels, and use this averaged value for a display source or for setpoint

activation.

2.2 - Display brightness

To adjust the display brightness, press the and buttons together from the main display. BRI appears and toggles with the current setting. Use the and

buttons to adjust the LED backlight, and then press to nish.

2.3 - Up and down button shortcuts

Pressing the and buttons from the main operational display allows instant

access to a number of values held in the controller's memory. These variables will ap-

pear in the order shown in the table below, and will cycle continuously at each press

of the or button.

3.2 - Analog input

See 3.1D

Wire the analog input module as shown, referring to the

product label. The unit accepts up to four process inputs.

Note that you must start wiring from channel 1. (I.e. For 2 channels, use CH1–2, not CH3–4).

(see 3.7)

3.3 - Relay outputs

See 3.1A

If your controller has relay

outputs tted, wire them as

shown. Relays can be pro-

grammed to operate within

the total span range of the

controller.

3.7 - Power supply

See 3.1F

DO NOT attempt to wire your controller while the power is on. NEVER connect your low voltage controller to mains power.

Wire your controller for low or high voltage power supply, as show in the diagrams

below. Check the label on the unit against the colour of the connector:

› Orange =

High voltage (85–265V AC,

95–370V DC)
