Key Features and Notes:

1. Universal (Sink/Source) Input: This is a crucial feature. It means the module can be wired in either configuration:

• • Sinking (NPN): The field device provides the ground (0V) to the input point. The common is connected to +24V.
  • Sourcing (PNP): The field device provides the +24V to the input point. The common is connected to 0V (Ground).
  • This flexibility simplifies design and spare parts inventory.

2. Grouping: The 24 points are organized into three isolated groups of 8. Each group has its own common terminal. This allows you to use different power supplies for different groups if needed for safety or noise isolation.

3. LED Indicators: Each point has a green LED that lights up when the input is active (ON), providing excellent visual diagnostics for troubleshooting.

4. Part of the VersaMax Line: While used in Series 90-30 systems, this module shares its design with the VersaMax product family, known for its modularity and reliability.

Typical Applications

This module is used to interface with a wide variety of industrial 24V DC control devices, including:

• Push buttons
• Limit switches
• Proximity sensors (PNP or NPN)
