20-750-ENC-1 Allen Bradley ncremental encoder module

The 20-750-ENC-1 supports Single-Ended or differential operation. It has a constant current sink operation with approximate consumption of 10 mA. The modules operates as an input voltage range of 5VDC – 15VDC with sourcing current consumption of 10 mA. The encoder’s channel has a minimum high state voltage of 3.5VDC while the maximum low state voltage is 0.4 VDC. Wire connection to the encoder module must not be more than 30 m (100 ft) at 5V, 183 m (600 ft) at 12V. It is compatible with input devices that has a switching frequency of 250 kHz. This encoder module supports Powered by Drive and Separately Powered Encoder supply configuration. It has a TB1 terminal that is composed of 14-pins for wiring of signal and supply voltage.

The 20-750-ENC-1 module is a single incremental encoder feedback option module. It can be used with PowerFlex 753 and PowerFlex 755 drives in the Allen-Bradley PowerFlex 750 series. The specifications for the module input include the use of differential or single-ended operation or constant current sink operation at approximately 10 milliamps. The 20-750-ENC-1 module supports a minimum of 5 Volts DC to a maximum of 15 Volts DC sourcing voltage at 10 milliamps. The minimum high-state voltage is 3.5 Volts DC and the maximum low-state voltage is 0.4 Volts DC. The maximum cable lengths supported are 30 meters at 5 Volts DC and 183 meters at 12 Volts DC. The maximum input frequency can be 250 kilohertz. When not in use, the 20-750-ENC-1 should be kept in an environment where the ambient temperature range is between -40 and 70 degrees Celsius. To prevent damage, the module should not be installed in a drive which is installed in a corrosive environment. The recommended range for the relative non-condensing humidity around the module is from 5 to 95%. The module is rated by the CE, ABS, SEMI F47, KCC, EAC, RCM, and RINA standards.
