The Spectrum 1746SC-INO4I is an inbligent analog b module designed for use in Rockwell Automation's PLC-5 and SLC 500 control systems.It provides four independent 4-20mA b channels,each with 12-bit resolution,making it ideal for precise data acquisition in industrial environments.
This module is fully compatible with PLC-5,SLC 5/04,and SLC 5/05 controllers,and communicates via the 1746 backplane bus,eliminating the need for external wiring.It features 1500V AC isolation between channels and ground,ensuring reliable perbance in electrically noisy environments.
Designed for ease of installation and maintenance,the Spectrum 1746SC-INO4I supports hot-swap replacement(when system configuration allows),minimizing downtime during module failures or upgrades.
Despite being a legacy module,it remains a critical component in many existing PLC-5 systems and is widely used in industries such as oil&gas,chemical processing,power generation,and water treatment for applications including temperature monitoring,pressure control,and flow measurement.
