4 - 20mA to Catalytic Converter
04200-M-5012
1. INTRODUCTION
The Signal Converter Module has been designed specifically to interface between
a bridge input circuit, which is typical of several control systems, and a
Searchpoint Optima 4 to 20mA output.
While this manual covers the use of the Signal Converter Module with the
Searchpoint Optima Infrared Detector, the Signal Converter Module can equally
be used to interface between other types of 4 - 20mA output detectors and a
bridge input control system.
The module allows users of an existing installation of catalytic detectors to
retrofit them with Searchpoint Optima Infrared Detectors without the need to
replace field cables or the control system.
