Instrument Overview
The CCD100 is a multi featured process display controller, capable of interfacing directly to
a mass flowmeter or other process transducers. This is the third generation of the Chell
CCD100 display.
The CCD100 is a single channel unit which can be used to operate a flow controller or
display the output from a pressure transducer. It supports both voltage transducers
(typically 5 & 10V full scale) and also millivolt transducers (max 250mV full scale). There is
also a secondary channel which can be used for external command (setpoint) control
(+10v full scale). The CCD100 also has the ability to power such devices with either
±
15dc
@ 250mA or +24vdc @ 300mA.
Interfaces to the CCD100 include RS232 (via USB), Ethernet or it can be used with just
analogue signals.
Note: This manual has been written for firmware version 1.00.
