Level Converter, Direction Signal Decoder and
programmable pulse divider
Product features:
• Level Converter (RS-422, HTL Single Ended, HTL Differential,
TTL and vice-versa
• Implementation between the two types of representations for the direction
of rotation (A/B 90 °, A/B Direction and vice versa)
• Adjustable division ratio of directional A / B pulses
• Adjustable division ratio for the Z pulse
• Reset of the Z divider by external input (defined setting)
• Zero setting of the A / B / Z divider by external input (defined Start / Stop)
• Z divider can also be used as an independent second divider
• Limit frequency up to 1 MHz, depending on the input format
• Push-pull outputs direct SPS control
• 9 to 30 VDC power supply
