Classification of measuring circuits (EN 61010-1)
Category I: 24 Vac/Vdc (J5, J7, J20)
Category III: 230 Vac (J8, J19)
Digital input current draw at 24 Vac/Vdc 5 mA
Digital input current draw at 230 Vac 5 mA
Important:
c.pCO SMALL, MEDIUM, BUILT-IN DRIVER, LARGE, EXTRALARGE:
•
separate as much as possible the probe and digital input cables from cables to inductive loads and power cables, so as to avoid possible electromagnetic
disturbance. Never run power cables (including the electrical panel cables) and signal cables in the same conduits;
•
the two 230 Vac or 24 Vac/Vdc inputs on terminals J8 (ID13, ID14) or J19 (ID15, ID16) have the same common pole and must therefore be powered at the same voltage
(230 Vac or 24 Vac/Vdc). There is functional insulation between the two inputs; there is reinforced insulation between the inputs and the rest of the controller;
•
ID1...ID8, ID9 to ID12, ID17, ID18 have functional insulation from the rest of the controller;
•
for DC voltage inputs (24 Vdc) either the + or the - can be connected to common terminal;
•
the rating of the external contact connected to the digital inputs must be at least 5 mA.

Warnings - c.pCO SMALL, MEDIUM, BUILT-IN DRIVER, LARGE, EXTRALARGE
•
for lengths greater than 10 m use a shielded cable with earthed shield;
•
a 0 to 10 Vdc analogue output can be connected in parallel to other outputs of the same kind, or alternatively to an external source of voltage. The higher voltage
will be considered. Correct operation is not guaranteed if actuators with voltage inputs are connected;
•
power the VG-VG0 analogue outputs at the same voltage on G-G0: connect G to VG and G0 to VG0. This applies in case of both alternating or direct current power supplies.

Insulation distance
The outputs can be divided into groups: between group 1 and 2 there is basic insulation. Group 3 has reinforced insulation from
the first 2 groups and can be powered at a different voltage.
