The Allen-Bradley 1771-DL is a sophisticated Gray code converter module that integrates smoothly with Allen-Bradley programmable controllers to deliver precise position tracking in automation systems. Designed for use with a 12-24V DC power supply and compatible with the bulletin 845A-SJZ3DN6DW 8-bit Gray encoder and 1771-WB wiring arm, the module efficiently converts absolute encoder data from an 8-bit Gray code into an 8-bit binary number. It features a zero-speed triac switch that ensures safety by turning off upon detecting stopped motion, with a selectable delay adjustable via a front-facing trim pot. With a compact size of 1" x 6" x 10" and weight of 0.43 kg, the module supports an operating temperature range of 32 to 140 degrees Fahrenheit and offers reliable performance with keying between specific pins and robust power specifications suitable for high-demand environments.
