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 certification.
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
identified.
Plug-in BA3400 series Pageant DI Modules are CE marked to show compliance with the European
Explosive Atmospheres Directive 2014/34/EU and the European EMC Directive 2014/30/EU.
The modules are also UKCA marked to show compliance with UK statutory requirements Equipment and
Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations UKSI 2016:1107
(as amended) and with the Electromagnetic Compatibility Regulations UKSI 2016:1091 (as amended).

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
Notified Body CML B.V. and UK Approved Body Eurofins
CML have issued the BA3400 series plug-in DI modules
with the following apparatus certificates:
IECEx
ATEX
UKCA
The ATEX certificate has been used to confirm compliance
with the European ATEXr Directive for Group II, Category
1GD equipment, similarly the UKCA certificate has been
used to confirm 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 certificates 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.
