GE DL330 / D3-330

The DL330 modular CPU is capable of controlling 176 I/O points and has 3.7K words of program storage. This CPU supports the RLL programing language and can save programs internally to RAM or UVPROM. There is a built-in programming port that directly supports the hand held programmer.

In addition to different choices for program storage, you can also select some memory areas to be retentive. Retentive memory retains its state after a power cycle or a program to run transition occurs, as long as the memory backup battery is functional. Non-retentive memory resets to a logical "0" after a power cycle or a program to run transition occurs. You have to use dip switch to select the retentive memory options (the switches are discussed in the next section.)

The D3-330 has a 2-position dip switch for selecting retentive memory and jumpers for selecting UVPROM and RAM options.
