Dold SL9151.12 2-450K-OHM DC24V 0,2-20S, Level Sensing Relay, sku: 0050862

Level monitoring and control for conductive liquids and powders, e.g. maximum and minimum filling levels, overfilling and protection against dry runningMonitoring and control of the mixing ratio of conductive liquidsGeneral resistance monitoring tasks, e.g. limit temperature detection with PTCContact protection relay with time delay

• According to IEC/EN 60255-1
• 3 probe connections for 2-point and 1-point level control
• Also for use as moisture detector
• High interference resistance of the Measuring Circuit, which is isolated from the mains
• Max. wire length to the probes: 3000 m
• Large setting range: 2 ... 450 kΩ this permits differentiation between fluid and foam
• Separately adjustable response and release time delay 0.2 ... 20 s for MIN- and MAX-level
• Programmable for:
  - 2 separate controllable output relays for MIN and MAX level
  - Common controlled output relays for 2-point hysteresis level control
  - Open circuit operation
  - Closed circuit operation
• Measuring Circuit for probes works with internally generated AC voltage (approx. 30 Hz), electrolytic behaviour does not occur in the liquid
• For auxiliary voltages of 24 ... 415 V AC or 24 V DC
• LEDs for operation and state of contact
• 2 changeover relays with 1 changeover contact each
• IL 9151 and SL 9151 with safe separation according to IEC/EN 61140, IEC/EN 60947-1
• Devices available in 3 enclosure versions:
  IL 9151: Depth 59 mm, with terminals at the bottom for installation systems and industrial distribution systems according to DIN 43880
  SL 9151, MK 9151N: Depth 98 mm, with terminals at the top for cabinets with mounting plate and cable duct
• IL/SL 9151: 35 mm width
