Why Engineers Specify This Model
- High-Speed Counting: 10 kHz maximum input frequency handles fast-spinning turbine meters and encoder outputs without pulse loss.
- Channel Isolation: Each channel is galvanically isolated, eliminating ground-loop interference common in multi-meter installations.
- 32-Bit Counter Depth: Supports up to 4,294,967,295 counts before rollover — sufficient for continuous, unattended operation over extended periods.
- Seamless STARDOM Integration: Plug-and-play slot installation into FCN/FCJ base units with automatic recognition by the STARDOM engineering tool.
- Flexible Input Compatibility: Accepts voltage pulse, dry contact, and open-collector signals, covering virtually all field meter output types without external signal conditioning.
- Compact DIN-Rail Footprint: Designed for space-constrained control panels and remote RTU enclosures.

Application-Specific FAQ
Q: Can the AAP135-S03 S2 accept NAMUR sensor outputs?
A: The module accepts open-collector and voltage pulse signals. NAMUR (8.2 mA / 1.2 mA) sensors require an external NAMUR signal conditioner (e.g., Pepperl+Fuchs KFD2-SR2-Ex1.W) to convert to a compatible voltage pulse before connecting to this module.
Q: What is the maximum cable length for pulse wiring?
A: Yokogawa recommends shielded twisted-pair cable up to 200 m for voltage pulse inputs at frequencies below 1 kHz. For higher frequencies or longer runs, use a repeater or signal conditioner.
Q: Is this module compatible with FCN-100 and FCN-500 base units?
A: Yes. The AAP135-S03 S2 is compatible with all STARDOM FCN and FCJ base unit variants. Confirm slot availability and firmware version (R3.02 or later recommended) in your STARDOM engineering tool before installation.
Q: Can I use this module for frequency measurement (Hz) rather than pulse counting?
A: Yes. The STARDOM FCN firmware supports both accumulation (totalizer) and frequency measurement modes configurable per channel via the engineering tool function block library.
Q: Do you provide a warranty?
A: All units carry a 90-day functional warranty from date of shipment. Extended warranty and on-site commissioning support are available upon request.
