Semiconductor Gas and Pump Line Heating Functional Safety System

HALO® SLC Temperature and Safety Limit Controller

How controls should be done now and in the future. Integrated Functional Safety Control (IFSC) of both the process and safety limit control needs of thermal system. Utilizing a Single Hybrid Microprocessor and software specifically designed for Class B Functional Safety and Control.

Durex Industries’ HALO SLC process and safety temperature controllers are an integrated thermal solution combining temperature control, safety high limit control, heater current sensing, visual multicolored alarm indication, high/low temperature alarm, digital I/O, Independent Graphical User Interface (GUI), and RS 485/Modbus® communications. The HALO SLC controller represents a new convergence of technologies that improves thermal system safety, control and performance while substantially reducing costs of ownership.

The HALO® Temperature Controller and SENTINEL® Gas and Pump Line heaters are a superior thermal solution for semiconductor applications. One HALO temperature controller can monitor the performance and control the temperature of multiple heaters with up to 10 amp resistive loads. Independent current sensor monitoring of heater load provides engineers with a visual HALO indication of a heater or wiring failure.

HALO® Temperature Controllers Overview

Control where you need it - at the source!

Cost effective communications to access the data you need.

HALO SLC - Dual Modbus Ports
Allows local communication to local area network such as tool HMI (Human Machine Interface) and also connect separately to wide area network such as protocol gateway (Ethernet/IP, ETHERCAT) or SCADA (Supervisory Control and Data Acquisition).
