MK 9151 - level relay The MK9151 is used forLevel monitoring and control of conductive liquids and powders, e.g. maximum and minimum fill level, protection against overfilling and dry runningMonitoring and control of the mix ratio for conductive liquidsGeneral resistance monitoring, e.g. recording temperature limits with PTC (device to IEG 255, VDE 0435 section 303) Features3 electrode connections for 2-point and 1-point level controlThe metering circuit galvanically isolated from the mains is immune from high levels of interferenceMax. lead length to the electrodes: 1500 mWide setting range: 2 → 450 kΩ which enables differentiation between liquid and foamAdjustable response and fallback delay: 0.2 → 20 sProgrammable for working current principle (without bridge) or rest current principle (X1-X2 and/or X1-COM bridge)2 LEDs to indicate operating readiness and contact position1 changerOverall width 22.5 mm, protection class IP40 Input Liquid resistance 2 → 450 kΩ adjustable Switch point hysteresis approx. 3% (at 450 kΩ) approx. 6% (at 2 kΩ) Max. Cable length to the electrodes 450 kΩ / 50 m Set value/cable length 100 kΩ / 200 m 35 kΩ / 500 m 10 kΩ / 1500 m 5 kΩ / 3000 m Max. Electrode voltage/current (internally produced) approx. AC 10 V / approx. AC 1.5 mA Auxiliary voltage UH AC 220-240 V, 45 / 400 Hz or DC 24 V Auxiliary voltage range 0.85 → 1.1 UH Output 1 changeover Thermal current 5 A Switching capacity AC11: 3A / AC 230 V Conductive Level Probes Controller Relays Liquid Level Relays are used to monitor the levels of conductive liquids, and are available in Up/Down, Minimum, Maximum, and Fill/Empty variations. Liquid Level Relays are straightforward to install and safe to use. Application Examples Liquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media, and designed specifically to provide for the: Monitoring and control of liquid levelsProtection of pumps against dry runningAbility to detect liquid leaks in a systemControl of media mixing ratiosControl of liquid levels ; Number of Inputs 1; Mounting Style DIN Rail; Probe Voltage 10V ac; Supply Voltage 220 → 240 V ac; Overall Length 82mm; Overall Width 22.5mm; Overall Depth 99mm; Minimum Operating Temperature -20°C; Maximum Operating Temperature +60°C;
