# Digital output

The digital output consists of four individually isolated relay outputs. The relays are rated to 500 VACrms input to output isolation. The output pins comes in groups of three:

- One relay have a center pin (Out X common)

- Normally Closed pin (Out X NC)

- Normally Open pin (Out x NO)

The Out X common pin should be connected to the equipment which is to be controlled and the two other pins to a suitable High or Low level for the equipment to be controlled

- Max relay switch current is 2 A at 24VDC.

- If the output is connected to an inductive load a fly back diode is required, to prevent the relay tongue from welding towards a pole when opening the circuit.

- Max output cable length is 3 m.
