XBE-DC08A

Description

8-point DC discrete input expansion module for the XGB/XBC/XEC compact PLC families, opto-isolated and compatible with sink or source wiring. Rated for 24 VDC nominal operation with low input current and removable terminal block for easier wiring. Designed to add local digital inputs without increasing CPU size.

The Polar Energy Assessment:

The XBE-DC08A is an 8-point photo-coupled DC input expansion module in LS (XGB) family, offering standard 24 VDC operation, ~4 mA nominal input current, and an approx. 40 mm compact footprint suitable for right-side mounting on compatible PLC bases. It supports sink/source wiring and uses removable terminal blocks for field cabling; response time and filtering are managed via CPU parameters. This is a simple, low-power way to add discrete inputs to SU/H/ULTRA class controllers.

Pros

• Small footprint and 8-point granularity for tight panels.
• Opto-isolation for noise immunity and reliable signal separation.
• Low nominal input current (~4 mA) reduces supply loading.

Limitations

• Fixed 24 VDC nominal (check DC16B if you need wider voltage range).
• Requires terminal block and cable planning when using many modules.

Typical use cases

• Adding a few discrete sensor inputs to packaging machines, conveyors, or OEM control panels.
• Field retrofit where full rack expansion is unnecessary.
