18. NW64404/08/12 Analogue 4/8/12 channel adaptors
18.1 General
These adaptors provide input ports for analogue data with voltage
levels between -10V to +10V and -20mA to +20mA current.
Depending upon the port-wiring combination, a choice may be
made for voltage measurement or current measurement.
18.2 Mounting
These adaptors connect to the DIN busbar by mounting them from
the top first and only in a vertical direction. Once the adaptor is
attached to the DIN rail it should not be shifted in a horizontal
direction (!) since this will render the feathering contacts between
the adaptor and the DIN useless and the system will fail beyond
repair.
18.3 Power Supply
These adaptors receive their power (indirect PoE converted to 24V DC) via the DIN rail mounted
NW6410 Buscoupler.
