Wired fixed gas detection - SA-220 to SCX

SA2 Smart Sensor Modules in our SA-220 or SA-220B detectors wired back to an SCX control system. Local relays, Modbus RTU, and 4-20 mA outputs keep safety decisions local while feeding Foresight or your existing SCADA.

System Architecture

Safety layer first, then data

The SCX controller receives readings from wired SA-220 detectors and 4-20 mA devices. Local relays drive sirens and strobes; Modbus RTU carries data to Foresight or your customer SCADA.

Safety-first design

Relays and local alarms operate even if the network or cloud connection is lost.

4-20 mA & Modbus RTU

Standard industrial interfaces that drop into existing DCS/SCADA infrastructure.

Smart sensor auto-ID

Detectors recognize the SA2 module and push configuration to the SCX automatically.

Fast commissioning

Plug-and-play startup reduces field configuration time and commissioning errors.

Local + remote alarms

Local relay-driven with optional sirens and strobes, plus Foresight alerts so the right people know immediately.

SCADA integration

Outputs and registers map cleanly into your customer control system.

Hardware

Built from the Sensor up

SA2 Smart Sensor Module

Swappable cartridge for H2S, LEL, CO, O2, NH3, Cl2, CO2 and more. The detector reads the cartridge automatically and applies the correct calibration curve.

SA-220 / SA-220B Detectors

Single and dual-gas fixed detectors that accept the full SA2 smart sensor module range. Auto-configure gas type, range, and serial number at startup.

SCX Control System

Scalable control system with color HMI, local relays, Modbus RTU, and 4-20 mA output. Models from 4 points up to 32 sensors plus distributed analog devices.

Foresight

The same wired system, seen through Foresight.

Site Overview

Every detector, channel, and current status across the site in one live picture.

Trends

Live gas channel readings with warn and alarm thresholds, plus multi-day trend history you can export.

Alarms and Classification

Alarms triaged by area and severity, with acknowledgement and action history.

Reporting

Exportable compliance and calibration records generated from detector telemetry.

Key Benefits

  • SA-220 and SA-220B detectors auto-configure with the SCX on power-up - no manual range or gas-type entry
  • Modbus RTU and 4-20 mA outputs feed Foresight or your existing SCADA without replacing the safety layer
  • Local relay-driven with optional sirens and strobes, keeping alarms independent of cloud or network connectivity
  • Scales from 4-point stand-alone to 32-sensor SCX networks with distributed analog inputs

Typical Use Cases

  • Oil & gas production, processing, and compressor stations
  • Water and wastewater treatment plants
  • Chemical, food & beverage, and manufacturing facilities
  • Landfill gas and environmental monitoring sites

Outcome Metrics

  • Continuous 24/7 gas monitoring with status on every sensor point
  • Alarm, calibration, and maintenance records centralized in Foresight
  • Compliance-ready documentation and audit trails for safety inspections
