Classifi cation of measurement circuits (IEC EN

Category 1 (J5, J7, J20) 24 Vac/Vdc - Category 3 (J8, J19) 230 Vac

(B4, B5, B9, B10)
5 mA
Digital input current with 24 Vac voltage signal
5 mA
Digital input current with 230 Vac voltage signal 5 mA
WARNINGS:
- IDH digital inputs 230 Vac 50/60 Hz (10/-15%) protected by a single 500 mAT fuse;
- the two 230/24 Vac inputs at J8 and J12 have the same common and so both will be either
24 Vac/Vdc or 230 Vac. There is double insulation between the two inputs and the rest of the controller;
- the external contact connected to the digital inputs must have a minimum current of 5 mA;
- for DC digital inputs (Vdc), either the + or the – can be connected to the common (IDC1).
Note:
separate as much as possible the probe signal and digital input cables from the cables to inductive loads and power cables,
to avoid possible electromagnetic disturbance.

When confi gured as fast digital inputs, B4 and B5 can measure a signal with a maximum frequency of 2 KHz and a resolution of ±1
Hz. This is possible as the BIOS provides the application program two pairs of variables that count the zero crossing of the input
signal and the corresponding frequency in Hz.

WARNING:
the 21 Vdc available at teVdc (J2) can be used to power any active probes; the maximum current is 150 mA,
protected against short-circuits. To power the 0 to 5 Vdc ratiometric probes, use the +5V
REF
(Imax: 60 mA) available at terminal J24.
Only use these voltages to power the active probes connected to pCO
