MK Niveaurelais 9151N.11 2-450K-OHM AC220-240V

Product information

Control relay, level relay, for monitoring and controlling conductive liquids. 2 output relays each with one 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 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 differentiation 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
- active current principle (output relay activated in case of fault)
- inactive 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 overall 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
Contact protection relay with delay
