POWER:
The MX420-OP modules obtain power from
the 10+2 interconnection bus. Power originates from
an MX Base Module (see specification section).
4 to 20mA OUTPUT:
The Port-1 I/O terminal block is
at the top-front of the unit. Port-2 is directly below it.
On a 4 port model, Port-3 is at the bottom-front of the
unit with Port-4 directly below and behind it. Screw
terminal blocks are numbered from left-to-right as
follows:
