Measurement isolating transformer for frequency signals, configured with DIP switches
Type WAS4 PRO Freq |
| Short specification |
Measurement isolating transformer for frequency signals, configured with DIP switches f/DC measurement isolating transformer in 12.5 mm width, with external power supply: for transmitting, converting and isolating frequencies up to 100 kHz. Namur or 3-wire NPN/PNP sensors can be connected on the input side. Standard DC signals 0(4) to 20 mA/ 0 to 10 V are available on the output side. Internal potentiometer is used for zero and span calibrations. |
