OPTIGO OP5U
Controller with display
Optigo OP5U is a pre-programmed, configurable controller. It has 5
inputs/outputs and can be configured to control temperature, CO

,
humidity or pressure. All configuration and normal handling is done
using the display and the knob on the front. From revision R18, it is
possible to connect an external PT1000 setpoint device.

Installation
OP5U must be mounted in a DIN-standard casing (minimum 7
modules) or in a cabinet, either on a DIN-rail or, using the two screw-
pockets provided, by being screwed to any suitable flat surface in the
cabinet. The controller can also be mounted in a cabinet door or other
control panel, using a suitable front-mounting kit.
The controller must be connected to a 24 V AC safety insulating
transformer providing mains insulation.
Follow table 1 below for connection.

nected.

Digital inputs DI and UI are only intended to be used with
a potential-free contact or switch.
If the Optigo OP5U and active
sensors and actuators connected to it share transformer, it is
essential that the same transformer-pole is used as reference for
all the equipment. Failure to do so will prevent the equipment from
functioning as intended and may also lead to damages.
For best protection against disturbances, a shielded twisted-pair cable
should be used for wiring the sensors. Ground the shield at one end.
The protection provided by the equipment may be impaired by im
-
proper use.
