Compatibility and Selection Guide
The IC693CPU311 is not compatible with Series 90-30 PCM and CCM devices. It lacks a battery-backed clock, interrupt, and override features. Optional communication modules support Ethernet, FIP, Profibus, GBC, GCM, and GCM+ protocols. Memory can be expanded with an EPROM or EEPROM slot. The built-in serial port uses a connector on the PLC power supply module. Verify your existing hardware and power budget before selecting this baseplate for your application.
Installation and Maintenance
Install the IC693CPU311 in a Series 90-30 rack with adequate ventilation. Ensure the power supply provides 410 mA at +5 VDC. The operating temperature range is 32 to 140 °F (0 to 60 °C). Regular maintenance includes checking connections and cleaning dust from vents. For replacement or spare parts, contact PLC Source PRO for quick dispatch and technical assistance.
