SMC Sierra Monitor FieldServer FS-QS-1B50-1150 Protocol Gateway (New in Box)
The SMC Sierra Monitor FieldServer FS-QS-1B50-1150 is a compact protocol gateway engineered for continuous industrial automation, marine plant monitoring, and commercial Building Automation Systems (BAS). Designed to resolve protocol discrepancies across heterogeneous control architectures, the FS-QS-1B50-1150 bridges physical layer fieldbus hardware—including M-Bus metering loops, RS-485 serial multidrop lines, and 10/100 Base-T Ethernet backbones—into unified SCADA, DCS, or centralized alarm systems.
Constructed inside a ruggedized chassis with integrated DIN-rail mounting tabs, this unit features field-proven driver stacks supporting seamless translation across standard automation protocols such as M-Bus, Modbus RTU/TCP, BACnet MS/TP, and BACnet/IP. It operates without moving cooling parts, drawing low quiescent power over an ultra-flexible 9–30 VDC or 12–24 VAC supply range.

Key Features
- Bi-Directional Multi-Protocol Engine: Executes protocol conversion across M-Bus metering equipment, serial Modbus/BACnet fieldbuses, and upstream Ethernet networks.
- Dedicated M-Bus Physical Layer: Hardware-integrated M-Bus transceiver eliminates external level-converter boxes when linking heat meters, flowmeters, and energy nodes.
- Industrial Thermal Tolerance: Passive convection cooling qualified for wide temperature swings from -40°C up to +75°C inside enclosed control cabinets.
- Rapid Web-Based Diagnostics: Integrated FieldServer web GUI displays live packet monitors, bit error rates (CRC drops), and communication register states over Ethernet without special configuration software.
- Fail-Safe Power Acceptance: Wide input tolerance (9–30 VDC / 12–24 VAC) handles electrical drop-outs and engine cranking fluctuations common in vessel engine rooms and heavy industrial plants.
Applications
- Marine & Offshore Machinery Spaces: Aggregating bunker consumption flowmeters, lube oil heat meters, and chiller M-Bus loops into vessel Alarm and Monitoring Systems (AMS) or Ship Automation Systems (SAS).
- Building Energy Management (BEMS): Bridging electrical tenant submeters, chilled water calorimeters, and gas meters directly into BACnet/IP supervisory heads (Tridium Niagara, Siemens Desigo, Johnson Controls Metasys).
- Industrial Cogeneration & Boiler Plants: Extracting heat output data from isolated industrial M-Bus transducers and serving registers over Modbus RTU/TCP to programmable logic controllers (PLCs).
- Auxiliary Power Monitoring Skids: Centralizing auxiliary generator operational metrics across mixed legacy serial interfaces into plant-wide SCADA infrastructures.
Compatible Upstream & Downstream Systems
- PLCs & Automation Racks: Schneider Modicon, Allen-Bradley (MicroLogix, CompactLogix via Modbus TCP), Siemens S7 (via BACnet/IP or Modbus TCP), WAGO I/O System.

Frequently Asked Questions
What is the primary function of the SMC Sierra Monitor FS-QS-1B50-1150?
The FS-QS-1B50-1150 is a multi-protocol communication gateway designed to translate field device protocols—principally M-Bus, Modbus RTU/TCP, and BACnet MS/TP or BACnet/IP—enabling mismatched industrial devices to exchange data seamlessly with supervisory SCADA, PLC, or BAS systems.
Does this model require external level converters to read M-Bus instruments?
No. The FS-QS-1B50 hardware designation contains an onboard physical M-Bus transceiver (Port R2), allowing direct wiring to standard M-Bus metering slave devices without an external RS-232-to-M-Bus converter module.
Can the FS-QS-1B50-1150 run on shipboard 24 VDC battery distribution banks?
Yes. Its input range accepts 9 to 30 VDC, making it suitable for 24 VDC marine automation power panels and floating battery banks. A dedicated DC-to-DC isolated power conditioner is recommended to suppress voltage surges during heavy machinery switching.
What mounting styles are supported?
The unit features integrated DIN-rail clips designed for standard 35 mm symmetric DIN rails (EN 50022). It can also be wall- or backplate-mounted directly via folding rear screw holes.
