GDA-400 – controller for different sensors

GDA-400 with 4-20mA inputs

Four Channel Alarm Controller
  • Control system for up to 4 transmitters
  • Graphic LCD shows real-time monitoring
  • Complete calibration functionality
  • Non-volatile memory retains all configuration data
  • Optional discrete channel alarm relays

 

Bacharach’s GDA-400 controller is designed to provide simultaneous display and alarm functions for up to four fixed-system monitors with 4 to 20 mA inputs. Real-time data displayed on the LCD includes gas type and concentration, bar graphs and 30-minute trends.

The GDA-400 is equipped with a fault and three adjustable alarm levels per channel. Relay outputs allow control of audible and visual alarms, strobes, horns, and other alarm events. Options such as 4 to 20 mA or Modbus® RTU outputs and discrete alarm relays are easily added.

 

ATTENTION:

The system is dedicated primarily to cooperation with existing, installed gas sensors from different manufacturers.

In the case of design and installation of a new detection system, it is recommended to use MGS-500 or C3-NET sensors equipped with digital Modbus outputs, plugged to MC3 or ASIX control system.

The digital signal, unlike the analog 4-20 mA signal, is a non-modifiable and undeniable signal that guarantees above-average information security.
