Notes:

    In some models certain inputs are adaptable via wiring and software settings, and can function as digital, high-speed, analog and in certain models as TC or PT100.
    Adapting requires input pins. This reduces the number of digital inputs. Pin requirements:
    • Each high-speed requires 1 or 2 pins according to high-speed mode.
    • Each analog input requires 1 pin.
    • Each TC requires 2 pins per TC input
    • The first PT input requires 3 pins, and two additional pins for each additional PT input.
    Example: V91-2-UA2 offers 12 digital inputs. Implementing 2 TC inputs requires 4 pins, leaving 8 pins free. Implementing 2 PT inputs uses 5 input pins.
  1. The total number of digital inputs listed includes high-speed and adaptable inputs.
  2. The total number of digital outputs listed includes high-speed outputs.

Notes:

  1. Number of supported I/Os and I/O modules varies according to module
  2. The EXF-RC15 functions as a node in a Vision UniCAN network and connects to the Vision controller via CANbus and programmed in VisiLogic. The EXF-RC15 cannot be extended as regular I/O unit.
  3. The EX90 is housed in an open casing. Only one EX90 can be connected per PLC, as a single expansion module; Expansion adapter not required.
  4. Supported by Vision series. Not supported by M91 series.
  5. The total number of digital inputs listed includes high-speed inputs.. Example: the IO-D16A3-TO16 offers a total of 16 pnp/npn inputs. You can configure I4 as a HSC and I5 as a Counter reset; this reduces the available number of digital inputs to 14.
  6. The total number of digital outputs listed includes high-speed outputs. Example: the IO-D16A3-TO16 offers a total of 16 transistor outputs. You can configure 1 to High-speed output, reducing the number of available digital outputs to 15.
  7. Functions as local adapter. Can support up to 7 I/O modules
  8. 16-bit or 32-bit, depending on the PLC
  9. Also available as 12VDC – contact us for part number
