Combustibles (Catalytic 0-100% LEL) or

Combustibles (IR 0-100% LEL)

Gas Transmitter with Internal Alarm Relays

One Transmitter

with interchangeable

electrochemical, infrared

and catalytic plug-in sensors

FEATURES:

The GasPoint transmitter provides a 4-20 mA output signal that can be
connected to any control system (DCS, PLC, etc.). With advanced sensor
technology and microcontroller based operation, the GasPoint provides
continuous monitoring of hazardous gases.

The GasPoint transmitter can accept any GasPoint sensor type:

electrochemical, catalytic or IR (infrared). All plug-in sensor assemblies
are fi eld-interchangeable.

Full function sensor integrity test (auto) continuously advises gas

sensing ability and life ended

Non-intrusive, one-person calibration with auto zero and

auto span

Equipped with three 5-amp relay contacts—two gas alarm relays

(low/high) and fault alarm. Field-selectable normally energized/
de-energized and latching/non-latching alarm relay functions.

Two backlit alphanumeric LCDs advise all environmental and gas

hazard conditions as well as instrument and sensor status

Remote toxic/oxygen sensors can be installed over 3,900 ft./ 1,100 m

away; combustible sensors over 1,550 ft./475 m.
Kit can be installed at any time.

Alarm setpoints displayed on demand—simply press the

external button
Field programmable alarm levels
Backlight (auto) in low light conditions and alarm
Extensive fault diagnostics
2-way digital communication using MODBUS module

4-20 mA Gas Transmitter

Display advises:

 Gas type monitored
 Continuous (%LEL, %v/v or ppm)

readout of gas concentration

 Alarm level and type encountered

- LOW/HIGH or FAULT

 When sensor has failed its

automatic daily self-test

 “Sensor Replacement” and

“Sensor Expired” indications

 When to apply gas during

calibration

Special Features

Change gases monitored in the fi eld

at any time. The GasPoint Transmitter
will recognize the sensor installed
and test and reset itself to that sensor

type.
No junction box connection required.
Daily sensor integrity test (auto)

monitors sensor operation, length

of time sensor has been in service

and advises when sensor requires

replacement.
GasPoint allows you to set or change

calibration time and gas alarm
setpoints in the fi eld.

Select or modify the measuring range
using a simple dipswitch.

The optional plug-in MODBUS
expansion module provides an
addressable communications
interface (1-247).
