32-Channel Digital Output Module

(MDO32BNS)

Issue 7

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.

October 2005

The module, which is compatible with ‘dual-slot hot repair’, can be fitted in any of the ten I/O slots

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.

TECHNICAL DESCRIPTIO

PHYSICAL

The Digital Output Module is a 9U high PCB with integral front panel and rear connectors; a plug-in daughter board carries the Common Interface circuits. The general layout, location of

connectors, front panel components and the configuration links are shown in Figure 1-1

the

MECHANICAL CODING BLOCKS

All Input/Output modules carry two mechanical coding blocks equipped with pins which mate with holes in corresponding blocks in the chassis and prevent the module being inserted into the

wrong slot. The pins in the module blocks are factory installed in a pattern determined by the module and corresponding set screws are removed from the chassis coding blocks to enable fitting. Unused holes are plugged with set screws. The chassis coding block configuration for this module is shown in Figure 2-1.

EXTERNAL CONNECTIONS

Field circuits

The field load circuit shown in Figure 2-2 is the absolute minimum required for the safe connection of field loads to the Digital Output Module. For any unused channel which may never be switched on a dummy field load (4.7k ohm resistor of adequate wattage) must be used. If a channel may be switched on, the total load should not exceed 1.2 k ohm maximum. We

however, recommend the use of their 16 Channel Digital Output termination cards TDO16*IN which offer full connection facilities with indicating fuses, alarm outputs and dummy

(see Associated documentation).
