![MUL-D2/MUL-D4 signal converters for potentiometric sensor signals](https://telma.dev/images/produkt-mul.jpg)

## [Signal converters](https://telma.dev/produkte/messumformer/)

Safe signal conversion

The MUL-D2/D4 series of signal converters transform potentiometric sensor signals into standard signals 0…20 mA, 4…20 mA or 0…10 V – with 2 to 4 limit-value relays.

![Power Control PC1.8 to PC10 motor load monitoring](https://telma.dev/images/produkt-motorlastueberwachung.jpg)

## [Motor load monitoring](https://telma.dev/produkte/motorlastueberwachung/)

The motor as the sensor

The PC1.8…PC10 motor load monitoring units monitor the active power of 3-phase motors without external sensors – the motor itself acts as the sensor.

![SYR93 synchro-check relay](https://telma.dev/images/produkt-syr93.jpg)

## [SYR93 relay](https://telma.dev/produkte/relais-syr93/)

Synchro-check relay

The SYR93 synchro-check relay monitors the synchronism of machines or generators – for reliable coupling at matching frequency and phase.
