Technical Document
Specifications
Brand
DoldNumber of Inputs
1
Mounting Style
DIN Rail
Probe Voltage
10V ac
Supply Voltage
230 V ac
Overall Length
90mm
Overall Width
22.5mm
Overall Depth
98mm
Minimum Operating Temperature
-20°C
Maximum Operating Temperature
+60°C
Country of Origin
Germany
Product details
MK 9151N - level relay
Application
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
3 electrode connections for 2-point and 1-point level control
Measuring circuit for electrodes works on AC voltage generated internally in the device (approx. 30 Hz); therefore no electrolysis occurrence in the fluid
The measuring circuit galvanically isolated from the mains is immune from high levels of interference
Max. lead length to the electrodes: 3000 m
Wide setting range: 2 kΩ → 450 kΩ which enables differentiation between liquid and foam
Response and fallback delay: 0.2 s → 20 s, adjustable separately for MIN and MAX level
Programmable for operating or rest current principle
LEDs to indicate operational readiness and contact position
Output contact 2 changeovers
Overall width: 22.5 mm
Approvals
CE
Standards
IEC/EN 60 255, DIN VDE 0435-303
