Bacharach's GDA-400 four channel controller is designed to provide simultaneous display and alarm

nnnn

functions for up to four monitors with 4-20 mA inputs. A graphic LCD displays monitored data as gas

nnnn

type and concentration, bar graphs and 30 minute trends. Three adjustable alarm levels are provided

nnnn

per channel. Relay outputs allow control of audible and visual alarms, strobes, horns, and other alarm

nnnn

events.

nnnn

Easy Configuration and Simple Calibration

nnnn

The Bacharach GDA-400 is equipped with a fault and three alarm levels per channel with features such

nnnn

as ON/OFF delays, latching relays, and alarm acknowledgement. A dedicated horn driver circuit for a

nnnn

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

nnnn

voting" menu to trigger relays based upon various alarm combinations. If more relays are required an

nnnn

optional relay board can be added.

nnnn

The GDA-400 is easy to configure and offers flexibility to meet the most demanding applications. A real-

nnnn

time clock and calendar are standard and non-volatile memory retains all configuration data indefinitely.

nnnn

Options such as 4-20 mA outputs, discrete relays for each alarm are easily added. RS-485 (Modbus®

nnnn

RTU) or Ethernet (Modbus® TCP) ports are also available for sending data to PC's, PLC's, DCS's, or other

nnnn

controllers. The GDA-400 also has complete calibration functionality for each input channel. This unique

nnnn

feature allows maintenance and service personnel to use the controller to calibrate the Bacharach

nnnn

GDX-150 simple sensor.
