The Didactum 500 and 600 appliances have the ability to connect up to 4 loads managed by built-in relays. In the case of the 500 appliance built-in relays, these have independent inputs and outputs. In the case of the 600 appliance, the power is applied to all the inputs of 4 built-in relays. The appliances use latching relays, so when the power on the appliance switches on or off, the relays remain in command position!
The maximum possible total input current on 4 relays: 10A
The maximum current load on the relay: 5A
