The GD 4020 two-channel user confirmable control unit is now available from Gas Detection Australia and can be used in conjunction with the 2500 series 4-20mA gas sensors. All Gas Detection Australia control units have been engineered for industrial applications and tested to emc (electromagnetic compatibility) and RFI (Radio Frequency Interface) standards.

The GD 4020 is mains powered 110- 220v ac and features all the power requirements for sensor and alarm circuitry. Each channel can be simultaneously shown on the LCD display, whilst also presenting the concentration and units. The unit is housed in a slimline ABS plastic box (IP 55) but can easily be upgraded to (IP 65) upon request.

The two-channel control units feature an internal sounder which can be muted via the front panel. Each channel has 3 SPCO relays (volt free), which can be used for alarm level 1, alarm level 2 and alarm level 3. A Reset button enables the alarm relays to be reset when the alarm condition no longer exists.
