Introduction

Purpose

The TDI16EIA 16-channel digital input termination card acts as an interface between the digital
signalling

It provides:

•

devices in the field device and the digital in

An Elco connector for the field wiring

put circuits of an SC300E chassis.

)

•

Power supply inputs for the field devices

•

Fuse protection for the field loops with local and remote indication of fuse failure

•

Overvoltage and transient protection

This

document is intended to provide a general understanding of the function of the TDI16EIA,

sufficient

to

enable basic maintenance operations to be effected in the field.

TECHNICAL DESCRIPTIO

PHYSICAL

The TDI16EIA comprises a PCB assembly mounted in a moulded carrier that can be snapped
onto all commercially available styles of DIN mounting rail. Connection to the chassis
backplane is via a multicore cable terminated at either end by a DIN41612 connector. Figure 2
2 shows the TDI16EIA with the DIN41612 connector attached and mounted on rail EN 50022
type NS 35/5.

Figure 2-1 identifies the main components on the PCB.
