range; Precision of active probe reading: ± 0.3% across entire voltage
range; Output precision: ± 2%
Digital
outputs Group 1, Switchable power R1: NO 1(1)A
Group 2, Switchable power R3, R4, R5: NO NO 2(2)A
Group 3, Switchable power R6, R7, R8: NO 6(6)A
Maximum switchable voltage: 250Vac
Switchable power R2 (SSR case mounting): 15 VA 110/230 Vac
The relays in the same group have basic insulation between each other
and therefore must have the same power supply
Relays belonging to diff erent groups have reinforced insulation and
consequently a diff erent power supply can be used
