Dräger REGARD-1

Product benefits

High flexibility

The Regard-1 can either be connected to a 4-20-mA transmitter or to Polytron-SE-Ex sensing heads. There are three alarm thresholds with flexible alarm analysis: rising or falling, latching or non-latching. The alarm status is displayed via three LEDs on the front. They will flash with a new alarm, they will light up continuously to display an acknowledged alarm situation or go out if there is no alarm. The gas concentration is displayed continually on a large LC display. If the alarm tresholds are exceeded or if a fault occurs, the integrated audible alarm will sound. To raise the alarm for a transmitter or system fault, a failure relay is available which has been configured accordingly. During maintenance, the maintenance relay can be used to report this special status via a remote display.

Robust enclosure

The robust IP65 enclosure enables the installation of the control system at virtually any location within the Non-Ex range.

Useful additions

The Regard-1 can be equipped with an optional TWA control module. This module enables the output of a TWA alarm as well as the output of the measured value and the alarm states via a digital interface. To ensure the operation of the Regard-1 during a power failure, two batteries of 1.2 Ah each can be inserted into the integrated battery compartment. Depending on the transmitter used, they will enable an operating time from 30 minutes up to two hours. The batteries are charged by the Regard-1.

Certifications

In accordance with the ATEX directive, the system is certified to EN 61779-1/4/5 and EN 50104 for explosion monitoring and oxygen measuring and, therefore, also suitable for applications which require the measuring function for explosion protection (primary measure in accordance with EN 1127-1, paragraph 6). In addition, the system was also tested independently to EN 45544 for the monitoring of toxic gases.
