Terminal number 67 ...................................................................................................................................... + 5 V
Terminal number 70 .................................................................................. Common for terminals 67, 68 and 69
Full galvanic isolation. See section entitled Galvanic Isolation.
Relay outputs:
Number of programmable relay outputs .............................................................................................................. 1
Terminal number, control card ......................................................................................... 1-3 (break), 1-2 (make)
Max. terminal load (AC) on 1-3, 1-2, control card ........................................................................ 240 V AC, 2 A
Min. terminal load on 1-3, 1-2, control card .................................................. 24 V DC 10 mA, 24 V AC 100 mA
The relay contact is separated from the rest of the circuit by strengthened isolation. See section entitled Gal-
vanic Isolation.
