Introduction
The EX682 Series of differential charge input amplifiers are designed to interface with differential output charge
sensors. The unit will convert the charge signal from any differential output charge sensor into a voltage output.
The front end differential charge amplifiers are designed to handle low sensor resistance that is common at very
elevated temperatures (>500ºF). An ICP
®
Din Rail Signal Conditioner is required for use with the differential
charge amplifier, to provide the appropriate power supply.
General Features

Din Rail Mount

Removable Terminal Blocks for easy wiring

35mm (1.38in.) Din Rail Mount configuration

Space saving 22.5mm (0.9in.) wide design
Installation and Wiring
Installation
The EX682 Series is designed to be mounted on a 35mm Din Rail. Do not install in a harsh area where it can be
exposed to cleaning fluids or machine oils. The unit should be mounted in a NEMA type enclosure to protect the
electronics from contamination.
CE Requirements
The EX682 Series is CE marked (see Declaration of Conformity for specific standards). To meet the requirement,
the unit must be installed in a grounded metallic enclosure and sensor cable shield terminated to enclosure.
Failure to do so can cause erroneous readings where high frequency noise is present.
