240 VAC + 5% is included in the tolerance range.
12...24 VDC (-55% / +30%); only available in non Ex version
12 VDC - 10% is included in the tolerance range.
24 VAC/DC (AC: -15% / +10%; DC: -25% / +30%); only available as Ex version
12 V is not not not not included in the tolerance range.
Power consumption AC: 7 VA
DC: 4 W
Signal cable Only necessary for remote device versions.
