INTRODUCTION
PURPOSE
The Analogue Input Module provides up to 32, low voltage or current analogue input signals. All
channel inputs into the module are resistively isolated from each other and galvanically isolated
from the system environment.
The basic module can be configured to meet a range of input specifications, the different
configurations can be identified from the module type number (see Section 1.3, Specification).
Circuit triplication and voting procedures make the module single-fault tolerant. A front panel
Channel selector and test points enable the metering of any channel, and indicators show the
circuit on-line status and the health of the module.
The module, which is compatible with ‘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 inputs are wired to 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
Analogue Input Module, sufficient to enable basic maintenance operations to be effected in the
field.
