Level converter for isolation and conversion of digital signals.

The universal level converter, direction decoder and potential isolation amplifier PW 1D-1D accepts at the input single track as well as double track incremental encoder signals, which can be either RS422 / TTL or HTL level (10 ... 30 V). If the signal is related to the direction of rotation, the direction can be specified either by a 90° phase offset of channels A and B or by a static direction signal.
In the control cabinet, the module is quickly and conveniently mounted on a standard DIN rail.

Features
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), adjustable to HTL, TTL or RS422 level.
Processes directional, synchronous, asynchronous as well as single track signals.
Signal outputs (A, /A, B, /B, 0, /0), adjustable to HTL, TTLor RS422 level.
Conversion of A/B direction information (90°) into single-state direction signal and vice versa.
Encoder connection either via Sub-D connector or pluggable screw terminals.

Benefit
Potential separation between sensor and control.
Level adaptation for older controls with direction signal input.
Conversion from TTL to HTL and vice versa.
Voltage-side level adaptation to application.
