GE IC693CHS398 I/O Expansion Baseplate for Industrial Automation
Ever needed to expand your PLC system’s I/O capacity without replacing the entire setup? The GE IC693CHS398 I/O Expansion Baseplate was built for this exact scenario. Designed to bolt onto existing GE 90-30 series systems, this baseplate gives you 6 extra slots for analog/digital modules while maintaining electrical compatibility. We’ve seen it deployed in everything from bottling plants to power generation facilities where system downtime isn’t an option.

Here’s where this part really shines – we’ve installed it in:

- Food processing lines adding temperature monitoring points
- Water treatment plants expanding valve control networks
Compatible with IC693CPU364/374 processors and standard 90-30 I/O modules. One customer in Texas just used this to retrofit their 20-year-old bottling line – saved them $15k vs buying new controllers.
