Bacharach's all new GDA-1600 Controller offers premier performance and functionality in a standalone

nnnn

controller. From one to sixteen channels, the GDA-1600 is designed to provide operators the most

nnnn

detailed, real time information about gas concentrations throughout the facility. Information is relayed

nnnn

to the operator through a large LCD display that shows real time gas concentrations, sensor location,

nnnn

sensor type, as well as historical data trends. Each channel has three independent, user-programmable

nnnn

alarm threshold values that allow for flexibility in alarm notification. When alarms do occur, operators

nnnn

are notified via LED alarm indicators on the front panel, clearly showing which channel is in alarm and

nnnn

the alarm state. Internal relays can also be utilized to control fans, horns, or beacons when alarm

nnnn

thresholds are exceeded. When responding to alarms, information is critical. The GDA-1600 provides

nnnn

more details than any other controller on the market today.

Centralize Monitor and Alarm Functions

nnnn

The GDA-1600 is equipped with a fault and three alarm levels per channel with features such as ON/

nnnn

OFF delays, latching relays and alarm acknowledge. A dedicated horn driver circuit for a local audible

nnnn

alarm is also standard. Two standard, 5-amp alarm relays are configurable via the "alarm voting" menu

nnnn

to make relays trip based upon various alarm combinations. If more relays are required optional relay

nnnn

boards can be added.

nnnn

Real-Time clock and calendar are standard on the GDA-1600. Options such as 4-20 mA outputs and

nnnn

discrete relays are easily added. RS-485 (Modbus® RTU) or Ethernet (Modbus® TCP) ports are also

nnnn

available for flexibility in sending data to PC's, PLC's, DCS's, or other controllers. The GDA-1600 has

nnnn

complete calibration functionality for each input channel. This unique feature allows maintenance and

nnnn

service personnel to use the controller to calibrate the Bacharach GDX-150 simple sensor.
