Dräger REGARD® 3920

The Dräger REGARD® 3920 is a standalone, self contained control system for the detection of Toxic, Oxygen and Ex hazards. The control system is fully configurable between 1 and 16 channels, depending upon the type and quantity of input/output boards installed.

Dräger REGARD 3920

Based upon the Dräger REGARD 3900 the 3920 is configured via on board pushbuttons and is capable of housing both 4-20 mA input boards and relay output boards in a robust IP65 enclosure. The Dräger REGARD 3920 is a modular system suitable for the most stringent of budgets.

Analog input board

Each analog input board caters for one to four, 2 or 3 wire, 4-20 mA transmitters. Each transmitter connects to dedicated field terminals. Up to a total of four analogue input boards can be installed in to a single Dräger REGARD 3920, thus giving a maximum input count of sixteen transmitters. Each individual input board is populated with three relays. These relays offer common Fault, Alarm 1 and Alarm 2 outputs. The two alarm levels are fully configurable and can be set as rising or falling, latching or non-latching. To differentiate between each input board a simple mechanical link is required.

Relay output board

Each relay output board is populated with eight additional SPCO relays. Relay 1 on each relay board is a dedicated Fault relay and cannot be reconfigured. The remaining seven relays can be configured as Single, Common, Voting, Inhibit or Nonoperational. An additional Alarm 3 level is offered by the relay board along with a second Fault threshold. All configurable relays can be Rising/Falling, Latching/Non Latching and Normally Energised/Energised on alarm. Alarm relays are acknowledged via the push button located on the front panel of the instrument housing. A maximum of two relay boards can be installed in a single Dräger REGARD 3920 control system.

Repeat output board

Each 4-20 mA output board repeats the signal of up to eight inputs. This allows indication or recording of gas levels by other units. A maximum of two analog output boards can be installed in a single Dräger REGARD 3920 control system.

System configuration

The Dräger REGARD 3920 is fully configurable via pushbuttons located on the front panel. The configuration menu allows quick and easy set-up. All calibration routines, zero and span are performed using the configuration menu.
