Connecting Relays

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!

Connecting relays

Connecting the load to 500 by relays

Connecting the load to 500 by relays
To connect an external load, first connect the wires from the external power supply to the appropriate medium (2) clamps of the relay terminal plug, the load to the left (1) or right (3) clamps of the plug. Insert the plug into the relay socket terminal RLY1 through RLY4. By command, the relay will switch the load either on or off. The maximum possible output current of the relay is 5A. Do not insert the terminal plug into the relay terminal socket RLY1 through RLY4 while external voltage source is turned on.

Connecting the load to 600 through outlets

Connecting the load to 600 through outlets
To connect an external load, connect the power cable from the load to the output "Output 1 through 4" of the appliance. By command, the relay will switch the load on or off.

Electrical characteristics

The maximum possible total input current on 4 relays: 10A
The maximum current load on the relay: 5A
