Solid state DC output relays for highly inductive loads at 24 V and for high DC-loads up to 250 (350) V. Current 1,8 and 4 A.
DIN-rail type is available only if it is in the list.
HIGH DC-VOLTAGE: These are fully rated up to 4 A in 250 (350) V DC systems. Because a normal mechanical relay has to be severely derated at this voltage, these relays provides solid state performance in a smaller package and at less cost than an equivalent derated mechanical relay.
INDUCTIVE LOADS: When used in 24 V systems these relays are resistant to heavily inductive loads without diodes in the poles of the load.
SLO ...CRA can be used with loads time constant of up to 100 ms at 1,8 A.
SLO ...CRA4 can be used with loads time constant of 100 ms at 2,5 A and with 50 ms at 4 A.
