Coding keyway structure: B coding adopts a unique keyway positioning system, and achieves incompatibility with A/C/D/X coding through physical foolproof design, effectively preventing the risk of mis-insertion when connecting fieldbus devices.
Rear panel installation: Install from the back of the device panel and fix it on the panel through threads.
Two-stage sealing design: Metal threads provide mechanical locking, silicone rubber sealing rings achieve IP67/68 protection, and withstand -40℃ to +85℃ ambient temperature and 10G vibration acceleration.
Signal transmission characteristics: Supports PROFIBUS DP/PA, INTERBUS and other field bus protocols.
Voltage and current: Supports a rated voltage of 250V and a maximum carrying current of 4A, suitable for the transmission of medium and low power signals.
Durability: High-quality brass or phosphor copper terminals are solidly gold-plated, with strong anti-oxidation ability, ensuring a plug-in life of more than 500 times.
Industrial control system: PROFIBUS master/slave device interconnection, PLC and remote I/O module communication.
Fieldbus network: process automation instrument connection (pressure transmitter, flow meter, etc.), distributed control system (DCS) node connection.
Industrial network equipment: industrial switch PROFIBUS port connection, device network (DeviceNet) trunk cable terminal.
Robot control: used for real-time communication interface between collaborative robot joint controller and servo drive unit.
