Bacharach GDA-400 Four Channel Alarm Controller

5700-0400 Bacharach’s GDA-400 Industrial four channel controller is designed to provide simultaneous display and alarm functions for up to four monitors with 4-20 mA inputs. A graphic LCD displays monitored data as gas type and concentration, bar graphs and 30 minute trends. Three adjustable alarm levels are provided per channel. Relay outputs allow control of audible and visual alarms, strobes, horns, and other alarm events.

Easy Configuration and Simple Calibration

The Bacharach GDA-400 is equipped with a fault and three alarm levels per channel with features such as ON/OFF delays, latching relays, and alarm acknowledgement. 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 trigger relays based upon various alarm combinations. If more relays are required an optional relay board can be added.

The GDA-400 is easy to configure and offers flexibility to meet the most demanding applications. A real time clock and calendar are standard and non-volatile memory retains all configuration data indefinitely. Options such as 4-20 mA outputs, discrete relays for each alarm are easily added. RS-485 (Modbus RTU) or Ethernet (Modbus® TCP) ports are also available for sending data to PC’s, PLC’s, DCS’s, or other controllers. The GDA-400 also 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.
