Control unit for Pump Stations with up to 2 pumps and a maximal current consumption of 9A per pump at 230V or 400V (1- and 3-phase operation).

Input signal by Diver’s bell / pressure, Pressure measurement with air-bubble introduction and blower monitoring (for atex restricted environment), Float switch (two digital inputs on board, third input on add-on module), Level probe / analogue input 4-20mA (0-400mbar)

Monitoring of Pump temperature sensor reversible (temperature guard), Pump temperature sensor irreversible (temperature limiter), Overcurrent, Overfill (digital, pressure, analogue), Pump-time duration, Minimal pressure at air bubble introduction (atex)

• Alarm outputs (pot. free & 230VAC)
• Manual operation
• Operating hours counter
• Forced switching-on can be preset
• Durable LED display for working-life > 10 years
• Due to its small dimension (210 x 200 x 110mm, HxWxD) the control unit is suited for narrow distribution boxes
• Add-on modules for a third digital input respective analogue input and / or module for mains failure detection and signaling (acoustic)
