Description

The TIDA-00400 isolated power supply reference design provides multiple isolated outputs to supply the bias voltage needed in a Programmable Logic Controller (PLC) IO module. It generates 3 isolated outputs: ±15V@30mA and +5V@40mA. These voltage rails can satisfy most of the required voltage rails in the IO modules, such as the Op-Amp, DAC bias, RS-485 transmitter and digital isolator power supplies.

Features

Remark: BOM is added with Schematic pdf.

  • Wide input voltage range: 18 to 30 V (24 VNOM)
  • Non-Isolated output: 3.3V with 50mA
  • Three isolated outputs:
  • +15V with 30mA
  • -15V with 30mA
  • +5V with 40mA
  • Small form factor for space constrained I/O cards 51 x 51 x 8 mm (L x W x H)
  • Primary-side regulation (no need for optocoupler) increases lifetime reliability

Typical applications

  • Analog Output Module
  • Digital Output Module
  • Analog Input Module
  • Digital Input Module
