ProtEX-MAX PD8-765 Explosion-Proof Process & Temperature Meter
Instruction Manual
7
Introduction
The ProtEX-MAX PD8-765 explosion-proof,
large-display, process and temperature meter offers
all the functionality of the PD765 Trident as a fully FM,
CSA, ATEX, and IECEx approved explosion-proof
product. PD8-765's huge 1.2" (30.5 mm) sunlight
readable display is visible from over 30 feet away.
This explosion-proof indicator can be field
programmed to accept process voltage (0-5 V, 1-5 V,
etc.) and current (4-20 mA) inputs, 100 Ohm RTDs,
and the four most common thermocouples.
The intensity of the display can be adjusted to
compensate for various lighting conditions, including
direct sunlight. The meter can be programmed and
operated without opening the housing by using the
built-in SafeTouch through-glass buttons or the
RS-485 serial communication port with free Modbus
®
protocol. Options for the PD8-765 process and
temperature indicator include 2 relays, a 4-20 mA
output, and a 24 V transmitter power supply.
SafeTouch Buttons
To make it possible to program and operate the
ProtEX-MAX in a hazardous area, the programming
buttons that are located behind the glass window can
be operated without removing the cover by using the
SafeTouch through-glass buttons. The operator puts
their finger on the glass over the button and the
button is actuated.
