SRAM Module The I-8074 series modules provide 128K to 1M Bytes memory. It contains two batters by capacity of 190mAh and the batteries monitor. When the voltage of the battery drops to 2.28V, the low battery indicator will light up. For this reason, the I-8074 series can replace the new battery before the battery fail; also the data stored in SRAM will not lose. SRAM size: 128K ~ 1M Bytes Battery backup: Yes Battery monitor: Low battery: 2.28V Battery fail: 2.11V Operating temperature:+0¢XC to +70¢XC

16-channel Digital I/O Simulator Module The I-8077 Digital Input/Output Simulator Module are designed to be an aid to program development. Use the I-8077 to simulator real world inputs/outputs during your design and debug process. The I-8077 enables the program development to cause a change in input/output status at will to simulate a system active. And you can monitor status of Digital input/output on the Led. When it becomes time to move to real hardware or control program, replace the I-8077 with the appropriate digital input/output module. The logic of your program will remain the same. Parallel I/O Module Digital Input Channels:8 Input type : Toggle switch Digital Output Channels:8 Output type : Programmable Power Consumption: 0. 3 W LED indicator for each channel of D/I or D/O
