230 Vac digital inputs (c.pCO Medium...Extralarge only)
Medium and Extralarge models feature one group of 230 Vac inputs
(terminal J8), while Large models have two groups (on terminals J8 and
J19). Each group consists of two digital inputs that can be powered at 230
Vac, indicated as IDH*, and two inputs that can be powered at 24 Vac/Vdc,
indicated as ID*. The two groups of 230 Vac inputs have double insulation
between each other and between them and the controller. The digital
inputs connected may be the 24 Vac/dc inputs from one group and the
230 Vac inputs from the other. The two inputs of each group have the
same common pole. Functional insulation is provided. In each group, the
digital inputs must be powered at the same voltage (24 Vac, 28 to 36
Vdc or 230 Vac) in order to avoid dangerous short-circuits and/or the
risk of powering lower-voltage circuits at 230 Vac
Note:
• the range of uncertainty of the switching threshold is from 43 to 90 Vac;
• the voltage must be 230 Vac (+10/-15%), 50/60 Hz.

5.4 Analogue outputs
c.pCOmini: analogue outputs without optical isolation
The controller features 0 to 10 Vdc and PWM analogue outputs without
optical isolation, powered directly by the controller. See the table of the
technical specications (output current, output impedance, etc., Chap. 12).
