Digital IO Board 2 Relays (DIO-002)

• 1.5 mm wide isolation slots and a large 14 mm creepage distance between the coil and contact side provide high levels of isolation and protection and allow low voltage circuitry to switch AC power safely.
• The driver circuitry has high and low inputs for interfacing to a wide range of equipment.
• Dry contact (buttons, switches, other relays), NPN-type outputs, push-pull type outputs and active-low signals connect to the relay card’s Low inputs.
• PNP-type outputs, push-pull type outputs and active-high signals connect to the relay card’s High inputs.
• A relay is triggered if the Low input is pulled below approximately 0.8 V, or if the High input is pulled above approximately 2.4 V.
• Voltage at either input should not be driven below 0 V or above the supply voltage 12 V.
• The circuitry for relay draws approximately 2 mA while deactivated and approximately 32 mA when the relay is active. 

Wiring:

Connection of terminal blocks

The connection sequence should be accurate.  Cable’s insulating striping length is about 7mm.  The power cable should be connected correctly.  Please double check before switching the router on.  Wrong connections may destroy the equipment.
