ATI: F/T System Interfaces (Digital F/T)

Connects to RS-485 bus and uses power from a user-supplied DC power source. The user’s computer converts the transducer output into force and torque data using ATI software. The electronics for this interface can be located on the transducer (except for Nano- and Mini-series transducers). Also available as an OEM interface option, the Net CAN OEM was designed to be integrated into small robot arms. The Net CAN OEM offers a CAN Bus and an RS‑485 serial interface to communicate with a host computer, which performs the necessary calculations using ATI supplied code.

Specifications:

• Output Format: RS-485 serial at up to 1.25 MBaud

• Maximum Output Rate: 7000 Hz
