Bacharach GDA-1600 Controller

The Bacharach GDA-1600 Controller offers premier performance and functionality in a standalone controller. From one to sixteen channels, the GDA-1600 is designed to provide operators the most detailed, real time information about gas concentrations throughout the facility. Information is relayed to the operator through a large LCD display that shows real time gas concentrations, sensor location, sensor type as well as historical data trends. Each channel has three independent, user-programmable alarm threshold values that allow for flexibility in alarm notification. When alarms do occur, operators are notified via LED alarm indicators on the front panel, clearly showing which channel is in alarm and the alarm state. Internal relays can also be utilized to control fans, horns or beacons when alarm thresholds are exceeded. When responding to alarms, information is critical. The GDA-1600 provides more details than any other controller on the market today.

The GDA-1600 is equipped with a fault and three alarm levels per channel with features such as ON/ OFF delays, latching relays and alarm acknowledge. A dedicated horn driver circuit for a local audible alarm is also standard. Two standard 5-amp alarm relays are configurable via the "alarm voting" menu to make relays trip based upon various alarm combinations. If more relays are required optional relay boards can be added.

Real-Time clock and calendar are standard on the GDA-1600. Options such as 4-20 mA outputs and discrete relays are easily added. RS-485 (Modbus® RTU) or Ethernet (Modbus® TCP) ports are also available for flexibility in sending data to PC's, PLC's, DCS's, or other controllers. The GDA-1600 has complete calibration functionality for each input channel. This unique feature allows maintenance and service personnel to use the controller to calibrate the Bacharach GDX-150 simple sensor.
