TEMPERATURE & LEAKAGE RELAY TYPE ABS CA 462

Helping detect leaks and temperature changes

CA 462 is designed to spy and detect temperature and leakage in pumps and mixers. The amplifier is housed in a norm enclosure fitted for DIN-rail mounting. The unit is available in two executions, 24 VDC or 110-230 VAC supply.

Description

Main design features

CA 462 is designed to spy and detect leakage and temperature in pumps and mixers.
The amplifier is housed in a norm enclosure fitted for DIN-rail mounting.
The unit is available in two executions, 24 VDC or 110-230 VAC supply.

To minimize the risk of false alarms the leakage failure has to be detected for time duration of approximately 10 seconds.

To simplify the mounting the unit is fitted with plug-in type of connectors.

The unit has separate alarm outputs for temperature and leakage.

CA 462 also has main contactor relay output energized depending on alarm/s with manual reset option.

Included in the kit is also a Xylem MiniCas adaptor.
