Installing the AMC-4W Access Controller AMC-4W

5.11. Connecting Relay Outputs

To operate locks or alarm systems the AMC-4W has eight form C relay
outputs.. Each relay output can operate in 'wet' mode, using the AMC-4W's
internal 12V DC power supply for external devices or 'dry' mode with potential
free contacts for externally powered systems.

Figure 24: Wet mode and dry mode of the AMC-4W relay outputs

Maximum switching power of each relay output using resistive load is 60 VA,
maximum switching voltage 30 V DC and maximum switching current 1,25 A.
If there is inductive load diodes should be installed across the DC load. Diodes
(BAX12A) are supplied with every AMC-4W package.
