3U Multi-channel Discrete I/O Board

Edit this on GitLab

Introduction

The NAI 68DT1 is a re-packaged configuration of NAI COSA® module types that provide a multifunction I/O board. It offers up to 96 channels of either 'Standard Function' (SF) DT1-type or 'Enhanced Function' (EF) DT4-type Discrete I/O function. The discrete I/O channels are mapped to 24 channels per module across four "virtual" modules within the board’s architecture:

  • Software Logical Module 1: Discrete Input Channels 1-24

  • Software Logical Module 2: Discrete Input Channels 25-48

  • Software Logical Module 3: Discrete Input/Output Channels 1-24

  • Software Logical Module 4: Discrete Input/Output Channels 25-48 (Optional)

Each channel can be configured as an input or one of three types of outputs. The I/O format (Low and High) registers are used to set each channel’s configuration.
