Description
DUB72 is a DC double under-voltage-thresholds monitoring relay, with two independent relays, one for each of the 2 thresholds, measuring the level of its power supply.
One of the thresholds, the one associated with the lower rating relay, can be used as a pre-alarm signal; the other one is associated with a highpower 20A-rated relay which can be used to drive the load directly.
This device is designed according to the Class I Div. 2 classification of the ISA12.12.1 hazardous location installation norm.
It features a low-profile DIN housing suitable for installation into electric distribution panels as well as industrial cabinets.
Benefits
• Under + Under Voltage setting. The user can set a double under voltage threshold, by two independent dials.
• 20A + 3A relay outputs. The two relay outputs, each one associated to one of the set thresholds, can be used to drive different types of loads: the 3A can be used to send a signal to a PLC while the 20A, thanks to its high capacity, could directly drive the load.
• Bicolour Alarm LED indication. A green/red LED provides a visual indication of the alarm status. The number of RED blinks indicates the triggered alarm type.
• Hazardous location installation. Thanks to the Class I div. 2 compliance, according to ISA12.12.1 Norm, the DUB72 is suitable for the installation in zone 2 of potentially explosive environments
• Tropicalized PCB. The PCB tropicalization increases the operation reliability also in humid and dusty environments.
