January 2008
Introduction
The XDP Explosion-proof Display Package has been designed as one
component of a system that monitors the composition of a binary gas.
The second component is a remotely-mounted sensor/transmitter,
such as the GE Sensing
Model TMO2-TC or similar device.
Note:
Refer to the documentation supplied with the specific
transmitter used for complete information on the transmitter.
The XDP performs the following basic functions:
•
supplies the 24 VDC required to power the transmitter
•
accepts and processes the 4-20 mA output from the transmitter
•
shows a selected process parameter on a digital display
•
provides a user interface for programming the system
•
provides user-configurable alarm relays and analog outputs
The XDP is wall-mounted via its integral mounting plate and it is
connected to the transmitter with an electrical conduit. Both
components can be rated for use in Class I, Division 1, Groups B, C &
D hazardous environments.
