Ametek BLW Controls 1500-D-L1-S7-0C-X Limit Switch

AMETEK BW Controls 1500-D-L1-S7-OC-X is a DIN-rail mounted liquid level control relay in the 1500 series, an induction-type device that switches up to 25 A on its 220 V secondary when powered from a 120 V, 50/60 Hz primary, designed for pump control in level-sensing applications.

Connections are via screw terminals, and the unit provides both normally closed and normally open contacts, with an OC-X open-chassis enclosure option to suit installation requirements.

The relay is intended for pump-down or pump-up logic in water and wastewater systems, commonly used to drive pumps based on sensed liquid levels.

Key verified specs include 1500-series induction relay technology, silver contacts, screw-terminal connectivity, DIN-rail mounting, and the open-chassis OC-X variant naming.
