1771-DL Gray Encoder Input Module .AB PLC-5 System Modules 1771-DL PLC-5 Gray Encoder Input Module,( 55142188,1) Digital Input for 12-24V DC 8-Bit Absolute Encoder with Gray Code format,( 55142189,1) 120V AC 0.5A Continuous Zero Speed Switch, compatible with PLC-5 Processors CPU PARTS Slc 500 System Processor Allen Bradley Slc 500 System,Plc Slc 500 System Processor The Gray Encoder (12-24 VDC) Input Module converts an 8-bit Gray code from an absolute encoder to an 8-bit binary number for input to an Allen-Bradley programmable controller. The module also has a 120 VAC zero-speed triac switch which is on while the Gray encoder is in motion. The switch turns off after a selectable delay when the module detects that motion has stopped. You can use this switch as a safety interlock to open the drive circuit after motion stops or if the encoder should fail. The Allen-Bradley 8-bit Gray Encoder (Bulletin 845A-SJZ3DN6DW is compatible with this encoder module. The encoder module is shipped with wiring arm (cat. no. 1771-WB).
