MK Niveaurelais 9151N.12 2-450K-OHM DC24V
Product information
Control relay, level relay, for monitoring and controlling conductive liquids. 2 output relays each with a changeover contact, LEDs for operational readiness and contact position.
- according to IEC/EN 60 255, DIN VDE 0435-303
- 3 electrode connections for 2-point and 1-point level control
- high immunity to interference of the measuring circuit galvanically isolated from the mains
- max. cable length to the electrodes: 3 000 m
- wide setting range: 2 ... 450 k, allowing distinction between liquid and foam
- adjustable pickup delay and release delay: 0,2 ... 20 s, separately adjustable for MIN and MAX level
- programmable for:
- 2 separately controlled output relays for MIN and MAX level
- jointly controlled output relays in 2-point hysteresis level control
- operating current principle (output relay activated in case of fault)
- closed-circuit current principle (output relay not activated in case of fault) - for auxiliary voltages from 24...230 VAC or 24 VDC
- LEDs for operational readiness and contact position
- 2 output relays each with 1 changeover contact
- IL 9151 and SL 9151 with safe isolation according to IEC/EN 61 140, IEC/EN 60 947-1
- 22,5 mm width
Application
- Level monitoring and control of conductive liquids and powders, e.g. maximum and minimum level, overfill and dry-run protection
- Monitoring and control of the mixing ratio of conductive liquids
- General resistance monitoring tasks, e.g. limit temperature detection with PTC
