Related Technical Topics
- Sinking vs. Sourcing DC Input — The 1734-IB8K is a sinking DC input module — field devices pull the input to common (0V). Pair with sourcing field devices (e.g., PNP proximity sensors). If your field devices are sinking (NPN), use the 1734-IV8K sourcing variant instead.
- Filter Time Tuning — Input filter time is programmable per channel — default is 1 ms with a valid range of 0…65 ms. Increase the filter for contact bounce on mechanical switches; decrease for high-speed sensors. Each input is independently settable in 1 µs increments.
- Conformal Coating — The -K suffix indicates conformal-coated electronics — suitable for harsh environments with condensation, corrosive vapors, or particulate contamination. Coating adds no performance penalty and meets IPC-CC-830 Class 3.
- Terminal Base Compatibility — Mount on 1734-TB (screw-clamp) or 1734-TBS (spring-clamp) 8-terminal base. The -TOP/-TOPS one-piece bases are also compatible. Do not use -TB3/-TOP3 12-terminal bases — pin arrangement differs.
