Load monitor max. 16 A | LM 1

Physical control devices are components for controlling electrical consumers depending on outdoor light, pressure, fill level, etc. Mounting tools and other additional products are available as accessories. Load monitors are electronic switches that switch on/off the electrical consumers (slaves) depending on another load (master). This allows current consumption peaks to be avoided. The load monitors of series LM detect the switching status of the master by directly measuring the current or indirectly through a transformer. The slaves are switched on/off in each case by a potential-free changeover contact. They are switched on when the fixed switch-on threshold is exceeded and switched off with the measured value drops below the holding current value. A hysteresis prevents excessive switching. With the LM 1 and LM 2 devices, the master is monitored by the direct current measurement up to 16 A; the only difference between the two devices is their monitoring ranges in which the threshold value can be freely adjusted.
