1747-PIC PLC Programming Cable RS232 to DH-485 Interface Adapter, Compatible with Allen-Bradley AB SLC Series PLC for Program Upload Download & Industrial Debugging

This 1747-PIC programming cable is a dedicated RS232-DH485 signal converter designed exclusively for AllenBradley SLC series PLC industrial control equipment, realizing stable communication between desktop serial ports and SLC PLC DH485 bus interface.

It perfectly matches all mainstream AB SLC 500 controllers including SLC 5/01, 5/02, 5/03, 5/04 and 5/05 models. Supported by RSLogix 500 and RSLinx industrial software, technicians can complete full functions: uploading ladder logic programs from PC to PLC, downloading backup programs from PLC, real-time online debugging, fault diagnosis and parameter modification without signal disconnection or communication timeout.

Built-in industrial dedicated conversion chip ensures strong anti-interference performance, which effectively filters electromagnetic noise generated by inverters, motors and high-power equipment in production workshops. The cable core adopts multi-strand tinned copper wire wrapped with integral aluminum foil shielding layer, greatly improving long-distance transmission stability.

Both DB9 RS232 serial port and RJ45 DH485 terminals use gold-plated contact pins, resisting oxidation, rust and poor contact after frequent plug and unplug operations. Reinforced strain relief at two ends prevents wire cracking caused by bending, pulling and vibration on-site.

It works with all Windows desktop systems equipped with standard RS232 serial ports, ideal for factory automation maintenance, mechanical equipment debugging, electrical engineering modification and industrial PLC daily overhaul. It is an essential communication accessory for automation engineers maintaining legacy AB SLC control systems.
