IO290

IO290 — Digital I/O module with isolated inputs, solid state FET outputs and LVTTL I/O lines.

Introduction

The IO290 I/O module is a digital module providing eight optically isolated non-polarized inputs with 3 to 31 VDC, eight fully protected FET output switches with 5 to 34 VDC at up to 2 A, and eight LVTTL I/O channels programmable as inputs or outputs in groups of 4 lines.

  • Eight FET output channels featuring:

    • High-side power MOSFET switches

    • 5 to 34 VDC output voltage range (must be supplied externally)

    • Up to 2 A (high-side) current rating per channel, max 5 A in total

  • Eight isolated input channels featuring:

    • Non-polarized, optically isolated from each other (polarity insensitive)

    • Up to 31 VDC input voltage range

    • Logical switching level

  • Eight digital LVTTL I/O channels:

    • Programmable as inputs or outputs in groups of four lines

    • Featuring digital outputs: 24 mA source, 24 mA sink
