TECHNICAL INFORMATION IN ITALICS BLUE BELOW WAS TAKEN FROM THE WEB:

General description The fundamental configuration and design of the GMA 200-MW16 gas warning controller ensures flexible, simple and clearly structured operation in industrial and commercial applications for measuring combustible and toxic gases/vapors, and for measuring oxygen concentrations.

Device design Up to 16 transmitters can be connected to the analog inputs of the GMA 200-MW16 gas detection controller with 4-20 mA or 0.2-1 mA output. A microprocessor evaluates the analog input signals of the connected transmitters, and a clearly structured display with LEDs indicate the status of the gas detection controller, each measuring point and the relays.

Site of installation

The GMA 200-MW16 is intended for indoor wall mounting and should not be installed in potentially explosive atmospheres. It should be installed in areas with as little vibration as possible. The voltage supply and transmitters are connected according to the terminal assignment diagram which is also located inside the terminal cover.

24 V DC voltage supply

The GMA 200-MW16 can optionally be operated with an installed power supply unit or with an external 24 V DC power supply. If external 24 V DC voltage is available and should be used to supply the GMA 200-MW16, it is connected via terminal X11a or, with a redundant design of the supply voltage, via terminal X11a and X12a to the terminal marked 24 V DC1 or 24 V DC2 and to GND.

Application

The GMA 200-MW16 is a gas detection controller for wall mounting. Combined with connected transmitters, it forms a fixed gas warning system for the continuous measurement of gas concentrations and is used to issue a warning about combustible gases or vapors in the range below the lower explosion limit and about toxic gases in the ambient air, as well as to measure oxygen.

External relay modules GMA 200-RT are additionally available.

The “GMA200Config” software program is required to configure the controller GMA 200-MW16 and the relay module GMA 200-RT.

The fundamental configuration and design of the GMA 200-MW16 gas warning controller ensures flexible, simple and clearly structured operation in industrial and commercial applications for measuringcombustibleand toxicgases/vapors,andformeasuringoxygenconcentrations.

Using the “GMA200Config” software program, it is possible to quickly and easily configure measuring points and relays even when extending already installed GMA 200-MW gas warning systems. Among other thing, measuring point designation, transmitter type, gas type and measuring range, as well as three individual or specified alarm thresholds, can be configured for each measuring point.

ZD21 Transmitter

Monitor O2 in difficult conditions

ZD21 Transmitter

Long-term monitoring of oxygen concentrations in difficult conditions

In many areas of application, oxygen concentrations must be monitored consistently. If harsh environmental conditions such as varying temperatures, high or low pressure or dry or humid air necessitate a particularly durable transmitter, the ZD21 is a good choice. The sensor operates with a zirconium dioxide oxygen pump cell. This measuring principle enables stable long-term measurement of O2 in difficult conditions and with short response times.

The ZD21 is characterized by its high selectivity and long-term stability. They can be equipped with oxygen sensors for different measuring ranges. These range from very low concentrations (0 to 1000 pm) to high concentrations (0 to 96 vol %).The sensor can also be installed remotely, with a maximum cable length of two meters between the transmitter and the external sensor.

Sturdy and durable

The transmitter housing is made of aluminum. It is protected against the ingress of dust and water (IP54). The O2 sensors have a sensor lifetime of approximately five years and are not susceptible to CO2. Temperatures between -30 and +50 °C, very low or very high humidity and extreme pressure do not affect the accuracy of the oxygen measurement.

Communication and service

Changes in the O2 concentration are detected within a very short time (t90 > 2 s). The ZD21 uses an analog (0.2-1 mA or 4-20 mA) signal to communicate with the controller. Test gases for function tests can be inserted via an optional calibration adapter. On-site adjustment can be performed by a single technician.
