<< | < | AX-MPTA - Pulsewidth to analogue converter
|
| |
|
The AX-MPTA converts a pulsewidth or phase cut input signal into a 0-10 volt analogue output. Various pulsewidths are selectable and if required the input can be isolated. The version 4 can convert a pulse output from a water meter to an analogue signal. The AX-MPTA is supplied in a DIN Rail carrier suitable for mounting on TS35 section DIN Rail and features high quality rising clamp terminals for ease of connection. |
