842D-60131331BDA

The 842D-60131331BDA is an absolute encoder from Allen-Bradley’s Bulletin 842D of DeviceNet Capable encoders. This encoder supports DeviceNet version 2.0 and supports standard DeviceNet transmission rates of up to 500 kBaud. It has programmable functions such as Electronic alignment with options of PRESET or NUMBER-SET sent over the DeviceNet network; Clockwise or Counterclockwise (CW / CCW) counting direction; Scaling feature for setting the resolution of the single-turn and number of turns; Programming of up to Eight (8) cams and Velocity warning flags. The 842D-60131331BDA is configurable for up to 8192 steps per turn or a maximum resolution of 26 bits while the single-turn position value is transmitted with 13-bits, configured through the scaling function. Similarly, the encoder’s maximum number of revolutions is 8192 as well. It has a 5-pin male micro quick disconnect cable that carries the Drain, Encoder Signal, and Supply voltage to the device. This encoder is provided with an LED status indicator specifically the Network Status LED installed at the back of the encoder. It is capable of providing Velocity Feedback such as Steps per second, revolution per minute (rpm), or RPS. The mechanical features of the 842D-60131331BDA include angular acceleration of 5 x 105 radians/sec2, 35gcm2 (5.0 x 10-4oz-in-sec2) moment of inertia, 6000 rpm operating speed at maximum shaft load with a maximum operating speed of 12000 rpm, starting torque of 2.5Ncm (3.5oz-in) and Shaft Loading of Axial 11lb (50N), Radial 67lb (300N). This encoder comes with a built-in protection rating of NEMA Type 4, 13, IP66 (IEC 529).

The 842D-60131331BDA encoder from Allen-Bradley/Rockwell Automation is a DeviceNet encoder. The 842D-60131331BDA DeviceNet encoder is an absolute encoder that can produce a total resolution of 26 bits. These 26 bits of resolution are made up of 13 bits of single-turn position value and another 13 bits of multi-turn revolutions. The 842D-60131331BDA DeviceNet encoder uses a gear mechanism to count its revolutions. The bus interface that is installed in this encoder has been configured as a DeviceNet slave device. This encoder is designed to connect to the DeviceNet network easily and it does not need any additional adapters to make this connection. Some of the key features of the Allen-Bradley/Rockwell Automation 842D-60131331BDA DeviceNet encoder from the 842 Encoders series include position error and diagnostic alarms, velocity feedback, velocity warning flags, a Network Status LED, a transmission rate of up to 500 baud, different types of I/O messaging, and as many as 8 programmable cams. It uses a DeviceNet drop cable to connect to the DeviceNet trunk cable that is connected to the DeviceNet network. The drop cable connects to the 842D-60131331BDA DeviceNet encoder’s 5-pin male micro quick disconnect electrical port. This encoder can be configured with DIP switches. The DIP switches are used to set the baud rate, the node address, and the DeviceNet bus termination.
