±0.3% of full scale
classifi cation of the measuring circuits (CEI EN 61010-1) Category I
Tab. 2.c
Note:
the Vdc available at the +Vdc terminal can be used to power any active probes.
The voltage dipends on the model:
+26Vdc +-15% per UPCA****** (230Vac)
+21Vdc +-5% per UPCB****** (24Vac/Vdc).
The maximum current is 150 mA, thermally protected against short-circuits. To supply the ratiometric
0 to 5 V probes, use the +5VREF (Imax: 60 mA).
2.7 Digital outputs
Insulation distance
Note:
the relays in the same group with basic insulation must have the same power
supply.
Makeup of groups
Version Group1
Group 2
Group 3
SMALL
1 to 6
7
MEDIUM
1 to 6
7
8 to 12
Note:
the relays in the game group have basic insulation between them; relays between
groups (group1, group2, group3) have double insulation
