Description

Digital Output Modules are a standard component in a PLC/PAC or DCS to control actuators, motors and other resistive, capacitive or inductive loads. Customers will benefit from this integrated protected low side driver with parallel interface as it makes the MCU interface easy to test together with a Beaglebone Black . The design is capable of delivering 0.5A on all 8 channels in a small form factor without compromising thermal management

Features

  • High density 8ch 24V low side digital output
  • 500mA /ch. unregulated (+20%), 2A peak
  • Parallel control for simple MCU interface
  • Capable of switching inductive loads
  • LED to indicate output state and faults
  • Beaglebone Black cape form factor for easy evaluation
