DESCRIPTION

The 84870210 is a DIN rail mountable level control relay designed for monitoring and regulating liquid levels. It operates on a wide supply voltage range from 24 to 240V AC/DC and can be configured for either filling (UP) or emptying (DOWN) functions via a front panel switch. Key features include a broad, adjustable sensitivity range from 250 Ω to 1 MΩ and an adjustable time delay of 0.1 to 5 seconds to compensate for wave effects. The unit provides a single 8A AC changeover relay output. This makes it suitable for a variety of industrial applications involving automated pump and valve control for liquid management.
