Product Overview

The Spirax Sarco GS-X range of panel-mounted programmable single-loop PID controllers is designed to optimize production yield for thermal and other processing applications. These controllers are ideal for digitized Industry 4.0 and "Industrial Internet of Things" (IIoT) applications, offering precise, repeatable control and measurement performance.

The GS-X1 and GS-X2 are suitable replacements for the SX80 and SX90 series respectively, providing advanced features in a modern package.

Key Features

• Enhanced PID Control: Includes cutback function for fast response and minimal overshoot.
• High Precision: 0.1% inputs meeting accuracy requirements of AMS2750F and CQI-9.
• Native Ethernet: High-speed Ethernet with RJ45 connector supporting Modbus TCP, EtherNet/IP, and BACnet.
• Flexible I/O: Wireable function blocks including math, logic, and advanced control.
• Setpoint Programmer: Up to 20 ramp/soak program profiles.
• Washdown Protection: Front panel sealing to IP66/NEMA 12 (washdown options available).

Operation and Configuration

The GS-X series uses a multi-level access system for security and ease of use:

1. Level 1 & 2: Operator levels for day-to-day operation.
2. Level 3: Supervisor level for PID tuning and setpoint limits. (Password: 0003)
3. Configuration (ConF): Full access to instrument configuration. (Password: 0004)

Backup and Configuration

A USB backup cable is available for convenient desktop configuration and backup. It powers the instrument even without the sleeve. The iTools software provides a comprehensive graphical interface for backup and configuration.
