1. INTRODUCTION

The BA3400 series plug-in DI (Digital Input) modules are

part of the BEKA Pageant Display system. Two models

are available:

BA3401 8 contact inputs

BA3402 8 NAMUR 2-wire inputs

Both models have IECEx, ATEX and UKCA intrinsic safety

apparatus certication.

The DI modules plug into any of the seven module sockets

at the rear of the BA3101 Pageant Operator Display.

Power for the module is provided by the BA3101 Operator

Display which determines the modules response speed.

If required multiple DI modules may be plugged into an

Operator Display.

Fig 1 shows a BA3400 DI plug-in module with its features

identied.

Each of the eight inputs is a separate intrinsically safe

circuit but they are not isolated from each other. Inputs

should therefore only be connected to isolated sensors and

wiring such as reed relays, switch contacts and proximity

detectors. The BA3402 can power and monitor the status

of 2-wire NAMUR compliant sensors, such as proximity

detectors. It may also be used to monitor switch status in

noisy environments.

In addition to their normal function, inputs 7 and 8 may

be used for the decoding a quadrature signal from a plant

position sensor or a BEKA BA490 rotary encoder.

2. INTRINSIC SAFETY CERTIFICATION

Notied Body CML B.V. and UK Approved Body Eurons

CML have issued the BA3400 series plug-in DI modules

with the following apparatus certicates:

IECEx IECEx CML 21.0004X

ATEX CML 21ATEX2110X

UKCA CML 21UKEX2111X

The ATEX certicate has been used to conrm compliance

with the European ATEXr Directive for Group II, Category

1GD equipment, similarly the UKCA certicate has been

used to conrm compliance with UK statutory requirements.

All BA3400 series DI modules carry both the CE and

UKCA marks, subject to local codes of practice, they may

be installed in any of the European Economic Area (EEA)

member countries and in the UK. ATEX certicates are

also acceptable for installations in some non EU countries.

These instructions describe IECEx, ATEX and UKCA

installations which conform with IEC / EN 60079-14

Electrical installations design, selection and erection.

When designing systems the local code of practice should

be consulted.

Instructions for BA3400 series Pageant plug-in Digital Input modules Each of the eight inputs is a separate intrinsically safe circuit but they are not isolated from each other. Inputs should therefore only be connected to isolated sensors and wiring such as reed relays, switch contacts and proximity detectors.

3.2 BA3400 series plug-in DI module Installation 1. The BA3400 series DI module may be fitted before or after the Operator Panel is installed. The Operator Panel should not be powered when the module is fitted. 2. Carefully insert the DI module into the selected slot at the rear of the BA3101 Pageant Operator Panel. When correctly positioned secure the module by tightening the two captive module fixing screws. 3. Connect field wiring to each of the eight pairs of removable input terminals shown in Fig 3.
