The normal open contacts can be used for voltages up to 240Vac or 24Vdc.
The minimum load is 10mA at a minimum switching voltage of 5Vac or dc.
The normal closed contact of relays 5 and 6 may only be used with a voltage of 24Vac /
24Vdc or less.
Do not use voltages higher than 24Vac / 24Vdc if the normal
closed contacts of relays 5 and/or 6 are used.
Although the first 3 relays have VDR’s on board in order to reduce the spikes due to the
opening of the relaycontacts, the customer must also use a snubber circuit in order to reduce
the spikes at the load side. For the other relays the same rule is applicable.
Do not exceed the maximum voltage and current.
In case of a non resistive load on the relaycontact, a derating is
necessary of the maximum current. For UL inductive loads of
type C300 / R150 are allowed.
