C.M.C. n.v. - Airmaster S1 installation guide – V1.2 – MANY0402A.00
The normal open contacts can be used for voltages up to 240Vac or 24Vdc.
The minimum load is 100mA at a minimum switching voltage of 5Vdc.
Although the first 4 relays have VDR’s on board in order to reduce the spikes due to the
opening of the relay contacts, 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 relay contact, a
derating is necessary of the maximum current.
