32-Channel Digital Output Module
(MDO32BNS)
Issue 7 October 2005
The Digital Output Module provides the output control interface between the SC300E
processing environment and up to 32 common low voltage field devices. 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
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 Digital
Output Module sufficient to enable basic maintenance operations to be effected in the field.
