Level Converters (HTL, TTL, RS422):

• This Universal Level Converter and Direction Decoder PU210 direction decoder and potential isolation amplifier accepts both single-track and two-lane incremental encoder signals at the input, which can optionally be designed as RS422/TTL or HTL level (10–30 V).
• If the signal is rotation-related, the direction can be determined by a 90° phase shift of channels A and B or a static direction signal.
• The signals A, /A, B, /B, and Z, /Z are available at the output, independent of the level and direction of the input signal. The direction of rotation is again available in formats A and B with a 90° phase shift or as a static signal.
• The output uses push-pull stages, with the output level approximately 1.5 V lower than the supply voltage of the device, which can range from 5 - 30 VDC.
