INTRODUCTION
PURPOSE
The 120Vac/dc Digital Output Module MDO16FNS provides the output control interface
between the SC300E processing environment and up to 16 high-voltage field items. All field
outputs from the module are galvanically isolated from the system.
Circuit triplication and voting procedures make the module single-fault tolerant and latent
testing ensures that the failure of a normally ‘ON’ (energised) or ‘OFF’ channel will be
recognised and reported to the system. Front panel indicators show the state of all channels,
the circuit ‘on-line’ status and the health of the module.
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
MPP software 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.
The MDO16FNS has relatively high power dissipation which may place some constraints upon
its use.
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.
