ABB VIPA 972-0DP01 PROFIBUS-DP Bus Connector

I. Basic Information
Brand: VIPA (now under the ownership of ABB)
Model: 972-0DP01
Product Type: PROFIBUS-DP RS485 Bus Connector (90° Side Out Wire)
Interface: Standard DB9 Pin Connector, with Programming and Debugging PG Port
Connection Method: EasyConn剥皮线 IDC Piercing Quick Connection
Shell： Full Metal Shielded Die-cast Zinc Shell， highly resistant to electromagnetic interference

Core Functions
PROFIBUS Physical Layer Connection
Enable PLC, Distributed I/O， Frequency Converter， Instruments， etc. to connect to the PROFIBUS-DP Field Bus， completing real-time data interaction between the controller and slave stations.
Switchable Terminal Resistor
Built-in 150Ω Bus Matching Resistor， controlled by the ON/OFF switch on the side； the connection terminals at both ends of the bus must be set to ON， and the intermediate nodes to OFF to eliminate signal reflection， prevent bus communication interruption， and prevent station loss.
Built-in PG Debugging Interface
Side预留an independent DB9 Debugging Port， no need to disconnect the bus to connect to a computer， programming device， download programs online， diagnose bus faults， and monitor communication status.
Peel-free Quick Connection
Red and Green labeled A/B Signal Lines， directly press-fit and fix， no need to peel the wire， construction is efficient， compatible with single-core and multi-core purple PROFIBUS standard cables.
