G6I-D21A

Description

8-point DC input module for 12/24 VDC signals, supporting both sink and source configurations depending on wiring. Suitable for conventional DC sensors and switches.

The Polar Energy Assessment:

The G6I-D21A is an 8-channel DC input module that accepts 12/24 VDC signals and is compatible with both current-sink and current-source wiring styles. It is optically isolated for noise immunity and designed to work in the G6/GLOFA Master-K rack system for standard digital sensing tasks.

Pros

• Flexible wiring: supports sink and source inputs for compatibility with most DC sensors.
• Compact 8-point module, easy to deploy for small I/O needs.
• Photocoupler isolation for robustness in noisy industrial environments.

Limitations

• Only 8 channels; may require several modules if I/O count is high.
• Must confirm on-voltage threshold and wiring polarity per installation.

Typical use cases

• Limit switches, low-voltage pushbuttons, proximity sensors, and other 12/24 VDC discrete inputs.
