Photoelectric detector with output to relay. Using the included probe, when light is received it activates the output for as long as the light is present. Includes sensitivity adjustment, LED indicator.
Darkness detector with relay output. Upon detecting an absence of light via the included probe, the output is activated and remains connected until the probe senses light.

Level detector with relay output. When the probe included with the module enters in contact with the liquid, the output is activated and remains in this state until the liquid is no longer in contact with it. Includes sensitivity adjustment, LED indicator and P. P.
Automatic Check for wells or tanks, with relay output. Has two control modes: wells or tanks. In both modes the circuit maintains between the minimum and maximum levels of water, activating the output accordingly.
Automatic detection of voltage decrease. By placing them in parallel with the device to be checked, when the voltage goes below the preset level, the modules activate a buzzer, producing a warning signal.

Automatic detection of voltage increases. By placing them in parallel with the device to be checked, when the voltage goes above the preset level, the modules activate a buzzer, producing a warning signal.
The circuit's acoustic warning will sound and alarm whenever the temperature increases by 1° C from the preset temperature. The alarm will cease when the temperature drops with respect to the preset temperature.
