2109-250F EC 21 Fixed Gas Transmitter with Internal Sensor, Ammonia (NH3), 2 ppm, 0 - 250 ppm by GfG

GfG s EC 21 transmitter for detecting toxic gases in ambient air is an inexpensive gas detection solution for use in a wide variety of today's industrial applications.

Simple gas detection

The EC 21 is the simplest way to monitor ambient conditions. Simply attach the EC21 to a GfG controller or a PLC to continuously and efficiently monitor the concentration of hazardous toxic contaminants in the air.

The EC 21 is reverse-wire protected to prevent damage due to incorrect wiring of the device. The power connector hasa "quick disconnect" feature to simplify transmitter installation and service.

Mounting Position of the EC 21

To determine the mounting position of the EC 21 it is important to know and consider the ambient conditions. To achieve the best results, the ventilation conditions and the density of the gases need to be considered.

The EC 21 must be installed so that the gas reaches the sensor even in poorly ventilated areas. If necessary, check the area with a smoke cartridge.

Other influences such as water (rain, dripping or condensation) and dust need to be considered as well.

Features

• Simple to use and extremely economical
• Robust housing is corrosion resistant and dust-tight>
• Linear 4 to 20 mA output signal
• 18 - 24 VDC

2200-004W GMA 200-MW16 Controller, Configured for 4 Measuring Points, Supply Voltage 24 V/DC, without Power Supply by GfG

The GMA 200-MW is our most flexible and advanced gas detection system controller. The design of the GMA 200-MW ensures simple and clearly structured operation in industrial and commercial applications. The system can be configured for control of any combination of GfG gas transmitters for the measurement of an extremely wide range of toxic and combustible gases and vapors.

Flexible modular design

Each GMA 200-MW module can control up to 16 individual gas transmitters (sensors). The self-contained, IP-65 wall-mounted housing facilitates cost-effective and space-saving installation. GMA 200-MW systems are scalable, and easy to expand by adding additional controller and relay modules. Optional gateway modules allow control via remote or touch-screen computer interface.

Easy to configure

Easy-to-use, menu driven GMA 200-MW software allows configuration of sensor type, gas type, measuring point designations, units of measurement, calibration curves, and function of the comprehensive and fully programmable relays. Up to three individual or specified alarm thresholds can be programmed for each measuring point. The GMA 200-MW continuously evaluates the analog input signals of the connected detectors.

Integrated relays

GMA 200-MW systems include comprehensive and fully programmable relays. Each controller is equipped with 8 internal relays. Menu-driven software allows easy assignment of measuring points to relays, single or multiple alarms per point, alarm thresholds, configuration of collective or group alarms, zoning, fault messages and voting functions.

Relay modules

GMA 200-RW relay modules are housed in easy to install IP-65 wall mounted enclosures. Each relay module provides an additional 16 freely configurable relays. A total of four additional relay modules (for 64 additional relays) can be managed by the same GMA 200-MW system. Digital connection with the GMA 200-MW controller allows remote positioning of the relay module wherever it makes the most sense, substantially reducing cabling and installation costs.

Remote terminal displays

Relay modules are available with or without an integral display for readings and system information, making it easy to add a remote terminal wherever needed.

Optional Fieldbus-Gateways

Optional gateway modules allow integration of the GMA 200-MW system into existing company networks based on TCP/IP, Process Field Bus or Process Field Network protocols. Monitoring and system performance data are easily exported for viewing or analysis. A wifi interface can be added to the gateway to allow wireless connection with a touch screen Windows® computer or smart-phone to display or access system information.

GMA 200 power options

GMA 200-MW power options include traditional voltage inputs (2 x 24 V DC, 20-30 V), as well as operation via a redundant, uninterruptible power supply (UPS), ensuring continued operation of the gas warning system even during a power outage.

Integral alarms

The GMA 200-MW includes built-in bright LED strobe light and loud audible alarms.

LED indicator lights

The status of the GMA 200-MW system (including operation, fault, service, alarm and relay status) is shown via LEDs. Individual LED indicators identify the type and severity of the alarm condition, (FLT, AL1, AL2, AL3), and any relays activated by the condition, (R1 through R8).

Datalogging standard

Measured values, mean values, alarm events and faults are permanently stored on a microSD memory card.

Graphical display

Currently measured values are displayed on a backlit, graphical LCD. In the event of an alarm the display changes color from green to red, and highlights the affected channels.

Five buttons enable operation at the GMA 200-MW controller. The main functions of the keyboard are the acknowledgement of alarms and the menu-driven operation. Information on the status of the controller, detector and the relays can be retrieved in the operating menu.

Operation via keypad

Operation of the GMA 200-MW is through easy-to-use menus, and a simple 5 button interface for alarm acknowledgement, and viewing information on the status of the gas warning system, detectors and relays. The intuitive push-button controls make it easy to navigate through additional screens of information. The integrated display enables the reading of alarm levels through the controller LCD for easy hazard assessment.

Configuration

A built-in USB port in the GMA 200-MW is used for connection to the configuration software. GMA 200-MW systems connected through a Fieldbus gateway can be remotely connected with a GfG factory service center for configuration, diagnostic or service evaluation.

Easy and convenient service
