XBF-HO02A

Description

Two-channel high-speed open-collector counter / encoder input module with two high-speed outputs, supports single-ended encoders and pulse inputs up to 200 kHz. External 24 VDC expansion power required, sinking inputs, suitable for fast pulse counting and simple encoder tasks.

The Polar Energy Assessment:

The HO02A is a compact XGB high-speed input module offering 2 high-speed input channels and 2 high-speed outputs, rated for up to 200 kHz switching frequency for single-ended signals, with support for 5/12/24 V input levels via dedicated terminals and typical photocoupler/open-collector wiring. It expects the XGB external 24 V expansion supply, and vendor manuals call out wiring, terminal block pinouts, and recommended shielding to reach top performance. Use it where standard discrete inputs are too slow but you do not need a full differential encoder interface.

Pros

• Up to 200 kHz counting, good for high-speed product counting and tachometry.
• Simple single-ended encoder support with flexible 5/12/24 V input terminals.
• Small, XGB-form factor, easy to drop into existing racks.

Limitations

• Single-ended only, less noise-immune than differential/line-driver inputs.
• Requires external 24 VDC expansion supply and correct terminal block cabling.

Typical use cases

• High-speed product counting on conveyors, basic RPM/tachometer inputs, and simple single-ended encoder feedback for compact machines.
