Relay outputs:
Number of programmable relay outputs
Terminal number, control card (resisitvie and inductive load)
Max. terminal load (AC1) on 1-3, 1-2, control card
Max. terminal load (DC1 (IEC 947)) on 1-3, 1-2, control card
Min. terminal load (AC/DC) on 1-3, 1-2, control card
The relay contact is separated from the rest of the circuit by strengthened isolation.
Note: Rated values resistive load - cosΦ >0.8 for up to 300,000 operations.
Inductive loads at cosΦ 0.25 approximately 50% load or 50% life time.
