Supply voltage can range from +5V dc… 240V ac, depending on relay load.
12/24V dc power for the module is provided by the external power supply.
The power supply voltage may be daisychained from a 1734 adapter, 1734-FPD module,
or 1734-EP24DC power supply communication interface. Each channel is individually
isolated and may have a unique supply or voltage as necessary.
