Notice!
Risk of damage to equipment
To prevent damage to the relays, note these specifications:
- The maximum switching current is 1.25 A.
- The maximum switching voltage is 30 VDC.
i
- Only OHM resistive load can be connected to the relay.
- Inductive loads have to be short circuited using recovery diodes. The diodes (1N4004) are
supplied with every AMC2.
- If you need higher voltage or current for special applications, or electric door holding
magnets, you have to use coupling relays (e.g. Wieland flare move) on the outputs.
- Note that the coupling relays must be selected according to the supply voltage (12 V, 24 V)
of the AMC2.

When you use the recovery diode, make sure to use it in the reverse direction.
