1. INTRODUCTION AND GENERAL
DESCRIPTION
The FLXA402 can work with the existing analog sensors
*1
(pH/ORP, conductivity, inductive
conductivity, and dissolved oxygen).
The FLXA402 can additionally work with the SA11 SENCOM
TM
Smart Adapter and its dedicated
sensors to provide measurements with digital sensors and multiple sensor connections
*2
of up to
5 sensors.
For the transfer of diagnostic data and other device information to a host system, the FLXA402
supports the HART and MODBUS protocols. This solution also facilitates connection to the cloud
and the construction of an Industrial IoT (IIoT) environment, for improved eld maintenance.
For further information, see GS 12A01F01-01EN.
This manual describes how to use the FLXA402 with Yokogawa’s or other companies’ sensors.
Please read carefully this manual and the instruction manuals relevant to those sensors you use
before using this instrument.
*1: Analog sensors here represent sensors , PH8E�P, SC4AJ, ISC40GJ, DO30G etc., which are connectable when Model and
Sux codes -P1, -C1, -C5, -D1 are specied in 1st or 2nd input.
*2: When -S5 on 1st input is specied, up to 4 pH sensors equipped with SA11 can be connected with a connection to BA11 Junction
Box.
