Features: DP bus connector is RS485 universal connection component between master station and slave station cable in process field bus DP protocol. Mainly used for unit level and field level of communication in manufacturing automation system, transmitting data in the form of round robin communications between PLC communication port and process field bus cable. Able to transmit signal in 12M bit transmission rate, with built-in terminal matching resistor. Considering cable input angle and relieve tension, built-in grounding metal effectively prevents common-mode interference and has strong electromagnetic compatibility. Easy to use, the bus cable can directly connect to the DP bus connector and plug connector port into the Process Field Bus master/slave station interface. Specifications: Model: 972-0BB12 Working Voltage: 24V Color: Black Material: ABS Operating Temperature: -30~70 Package Includes: 1 x Connector
