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 AMC2-4R4 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
