Level converter
PW 1D-1D

|
Level converter for separation and conversion of digital signals.
The PW 1D-1D universal level converter, directional decoder, and potential isolation amplifier accepts both single-track and dual-track incremental encoder signals on its input, which can be designed either as RS422 / TTL or as HTL level (10 to 30 V). If the signal is related to the direction of rotation, the direction can be specified either by a 90° phase shift of channels A and B or by a static direction signalThe module is quickly and easily mounted in the control cabinet on a standard DIN rail.

Characteristics
Benefits
- High frequency range up to 500 kHz.
- Potential isolation amplifier.
- Level converter and direction decoder for incremental encoder signals.
- Signal inputs (A, /A, B, /B, 0, /0) can be set to HTL, TTL or RS422 levels.
- Processes signals with direction, synchronous, asynchronous, as well as single-track signals.
- Signal outputs (A, /A, B, /B, 0, /0), can be set to HTL, TTL or RS422 levels.
- Conversion of an A/B direction information (90°) into a static direction signal and vice-versa.
- Encoder connection either with Sub-D connector or plug-in screw terminals.
Benefits
- Potential separation between sensor and control.
- Level adaptation for old controls with direction signal input.
- Conversion from TTL into HTL and vice versa.
- Voltage level adaptation to the application.
