Each relay output can operate in 'wet' mode, using the AMC2-4W 's internal 12/24 Vdc power
supply for external devices or 'dry' mode with potential free contacts for externally powered
systems.

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, see image below. These
diodes (1N4004) are supplied with every AMC2-4W package.
If you need higher voltage for special applications you have to connect external relays to
the outputs. Depending on the power supply mode, it is recommended to use the
following Wiegand relay types:
–
Flare move 12DC1W10A
–
Flare move 24DC1W16A
