4.12 Connecting relay outputs
To operate locks or alarm systems, the AMC2 has eight relay outputs. The outputs will be
connected to the 3-pin pluggable screw connectors S5, S6, S10, S11, S17, S18, S22 and S23 -
refer to chapter Connecting diagrams, page 46 .

Each relay output can operate in ‘wet’ mode, using the AMC2 internal 12/24 Vdc power supply
for external devices or ‘dry’ mode with potential free contacts for externally powered systems.

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.
- 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.
