For models equipped with MODBUS communication, network topology relies on correct RS485 polarization. Ensure the White wire (485A) and Orange wire (485B) are consistently routed to guarantee stable remote reading and setting from your central upper computer.
Wiring Definitions & Bracket Accessories:
The SP-18 eliminates the barrier between localized fluid mechanics and enterprise-wide data lakes, proving vital for expansive, high-precision manufacturing floors:
A: By adding a 5th digit to the 7-segment display, the SP-18 series breaks past the resolution limits of standard switches, allowing it to display measurements down to a maximum resolution of 1Pa (0.001kPa). This is critical for ultra-precise micro-pressure adjustments.
A: To fully utilize the expanded 5-digit display format without losing precision, the 18P series displays high pressure ranges up to 999.99 kPa instead of rounding to MPa. This ensures you maintain granular tracking across the entire high-pressure spectrum.
A: Models like the 030 and 031 provide RS485 communication for data logging, while preserving a physical 1-channel NPN or PNP output. This retained output ensures you always have a failsafe local hardware trigger for rapid safety cutoffs, regardless of network status.
