Pneumercator Isolated Quad ModBus RTU Interface Card (SKU: 900931-1-4) is a high-density, OEM plug-in card providing four fully isolated ModBus RTU RS-485 channels for advanced tank management data integration. Ideal for TMS3000 series and compatible industrial controllers, this unit enables simultaneous data polling from up to four automation, BMS, SCADA, or remote monitoring hosts—even across multiple network segments.

Industry-Standard Quad Channel RS-485 ModBus RTU: Each isolated RS-485 channel supports continuous register mapping for tank, sensor, leak, and alarm statuses. All wiring is plug-in and supports cable runs up to 4000 feet per channel. DIP switches on the card enable baud rate (9600/38400) and slave address selection (1–64) for each channel, while onboard termination resistors and TX/RX LEDs facilitate easy field setup and diagnostics.

No Console Programming Required: Configuration and installation are strictly hardware-based (DIP switch and terminal block), with clear status feedback via global receive and transmit LEDs. Compatible with TMS3000 firmware version Vxx.99.94 or later for extended mapping features and full remote register support.

Applications: Deployed in refineries, chemical plants, tank farms, generator installations, or remote environmental sites needing simultaneous, isolated serial data integration across four separate hosts or automation systems.
