INTRODUCTION

PURPOSE

The TDO16AIN 16-channel digital output termination card acts as an interface between the
digital output circuits of an SC300E chassis and the field devices which they control.

It provides:

•

Screw terminals for the field wiring

•

Power supply inputs for the field devices

•

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

•

Overvoltage protection

•

Dummy loads for unused digital output channels—to prevent spurious operation of

latent fault detection circuits in the associated digital output module. (Dummy loads
are only to be connected to outputs which are not used).

This document is intended to provide a general understanding of the function of the TDO16AIN,
sufficient to enable basic maintenance operations to be effected in the field.
