Zelio level control relays control one or two levels with fill or empty function. The settings are protected by a sealable cover, control status is indicated by an LED, and they are DIN rail mountable. RM35LM is designed to control levels of conductive liquid, and RM35LV is designed to control levels of other materials.

Application examples for RM35LM:

Application examples for RM35LV:

  • Detecting pump seal failures

  • Spring, town, industrial and sea water

  • Metallic salt, acid or base solutions

  • Liquid fertilizers

  • Non-concentrated alcohol (<40%)

  • Liquids in the food-processing industry: milk, beer, coffee, etc.

  • Chemically pure water

  • Fuels, liquid gasses (inflammable)

  • Oil, concentrated alcohol (>40%)

  • Ethylene, glycol, paraffin, varnish and paints

Zelio pump control relay RM35BA10 can operate on a single-phase or 3-phase supply. It incorporates three functions in a signal unit:

  • Over and under current measurement

  • Single or three phase

  • Phase presence control

 

It has two operating modes which are designed to control a pump via two external signal inputs (Y1 Y2). These two signals are controlled by volt-free contacts. Control inputs Y1 and Y2 can be connected to:

  • Level sensor

  • Pressure sensor

  • Level relay

  • Push button

Zelio speed control relay RM35SOMW monitors underspeed and overspeed conditions, with or without memory, with inhibition by an external contact. It operates with either N.O. or N.C. sensors. Adjustable time between impulses is 0.05 s to 10 min. Power-on inhibition time is adjustable from 0.6 to 60 s. Inhibition is controlled by an external contact. Settings are protected by a sealable cover, control status is indicated by an LED, and it is DIN rail mountable.
