GP-ZD GasPoint Transmitter with HCN Sensor Unit, Modbus Compatible by BW Technologies
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 field-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
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 field 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 field.
- Select or modify the measuring range using a simple dipswitch.
- The optional plug-in MODBUS expansion module provides an addressable communications interface (1-247).

Thank you for the opportunity to assist. We have checked your request and it appears that the part number GP-ZD is already discontinued and no direct replacements. You might want to check our other fixed gas monitors which are the Honeywell XCD and series 3000 models
