Dold Level Monitoring Relay, DIN Rail / 3277641

IL9151 - level relay with two separately operating changeovers. The IL9151 is used for. Level monitoring and control of conductive liquids and powders, e.g. maximum and minimum fill level, protection against overfilling and dry running Monitoring and control of the mix ratio for conductive liquids General resistance monitoring tasks, e.g. recording temperature limits with PTC Contact protection relay with delay. Features. In accordance with IEC 255, VDE 0435 Section 303 3 electrode connections for 2-point or 1-point level control The measuring circuit galvanically isolated from the mains is immune from high levels of interference Max. lead length to the electrodes: 1500 m Wide setting range of 4 → 450 kΩ, which enables differentiation between liquid and foam Response and fallback delay: 0.2 → 20 s adjustable separately for MIN and MAX level Programmable for: 2 separately controlled output relays for MIN and MAX level or jointly controlled output relays in 2-point hysteresis level control Programmable for: Operating or rest current principle Measuring circuit for electrodes works on AC voltage generated internally in the device (approx. 30 Hz); therefore no electrolysis occurrence in the fluid LEDs to indicate operational readiness and contact position 2 output relays each with 1 changeover 35 mm overall width
