Inputs and outputs
A
GND
All A
GND
terminals are interconnected and also connected to G0.
Analogue input AI
The analogue input must refer to an A
GND
terminal. The analogue input is for PT1000
temperature sensors only. Temperature range: -30…+54°C.
Note: For temperatures below -9.9°C decimals will not be displayed. So make sure to differ
between for example -2.
7
(minus two point seven) and -2
7
(minus twentyseven).
Digital input DI
The digital input must refer to DI+ on terminal 41.
The digital input may only be wired to voltage-free contacts. Any external voltage applied to
a digital input may seriously damage the unit.
Universal input UI
The universal input can, depending on the choice of application, be made to act as either an
analogue input or as a digital input.
When used as an analogue input it is for 0...10 V DC input signals.
When the Universal input is used as an analogue input it must refer to the A
GND
terminal or
directly to G0.
When used as a digital input it must refer to UI+ on terminal 43. It may then only be wired to
voltage-free contacts.
Analogue outputs
Analogue outputs must refer to a A
GND
terminal or directly to G0.
If the Optigo OP5 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.
