Appearance

FFC3232-2603 ​

Description ​

This controller model was the final test bed for software development and manufacturing.

Status: Manufactured, Unreleased

Hex: 0x32322603

Number of Inputs: 32

Number of Outputs: 32

Form Factor: Rack Mount

Power Input ​

  • Minimum: 7VDC
  • Recommended: 12VDC 6A
  • Maximum: 26VDC

Minimum Amperage Changed

The minimum power supply amperage changed to 6A with this version due to elimination of the 9VDC power system. Clients connected are now fed power directly from the power supply.
