INTRODUCTION
PURPOSE
The 4-Channel Analogue Output Module MAO04NND (Figure 1-1) provides analogue output
signals.
The module is a rack mounted, 9U high unit that provides the output control interface between
the SC300E processing environment and the user field environment. It has four current loop
output channels. All field outputs are galvanically isolated from the SC300E system but have a
common supply connection.
Circuit triplication and voting procedures make the module single-fault tolerant and latent
testing ensures that the failure of a channel will be recognised and reported to the SC300E
system. Front panel indicators show the state of the circuit ‘on-line’ status and the health of
the module. Sockets are provided on the front panel for monitoring the outputs.
The module, which is compatible with ‘dual slot hot repair’, can be fitted in any of the ten I/O
slots in the SC300E chassis. ‘Wrong slotting’ is prevented by physical coding. The SC300E
system software identifies the module via a built-in hardware identifier.
Channel outputs leave the module via the DIN 41612 ‘rear plug-up’ system on the chassis
backplane. This document is intended to provide a general understanding of the function of the
module sufficient to enable basic maintenance operations to be effected in the field.
