The IC693CPU311 is a 5-slot rack with an integrated CPU manufactured by GE Fanuc, designed as part of the Series 90-30 PLC family. This 16-bit system operates at a processor speed of 10 MHz and features 1 kilobyte of register memory. It supports up to 160 discrete input/output points, although it does not have floating-point math capabilities. The embedded CPU is fixed in place on the backplane board of the baseplate and lacks a time-of-day clock, along with expansion connectors, making it unsuitable for expansion or remote rack support. In the event of power supply removal or battery disconnection, the module is equipped with super capacitors that provide sufficient charge to maintain memory circuits temporarily. The IC693CPU311 operates with the IC693PWR330 high-capacity power supply, which delivers 30 Watts of output power and accepts 120/240 VAC or 125 VDC input. To ensure proper operation, the module can be tested by powering it on and verifying the 'OK' indicator LED on the power supply; a non-illuminating indicator suggests a malfunction in the CPU.
