Q1: What is the difference between the AIO208 and the AIO208/SI?
The AIO208/SI is a specific variant featuring galvanically isolated channels (SI = Single-Input or Special Isolation). Per-channel isolation (500 V) ensures electrical separation between channels and the system, which is critical for protecting sensitive control electronics and eliminating ground loop issues.
Q2: What does the "SI" designation mean in the part number?
"SI" typically denotes galvanic isolation per channel (from the German "Single-Input" or an isolation designation). For the AIO208/SI, this confirms that each of the 8 channels is individually isolated.
Q3: Can I mix input and output types on a single AIO208/SI module?
Yes. Each of the 8 channels can be individually configured as either an analog input, an analog output, or a temperature input. Additionally, because input and output are available on every channel, a secondary unused channel can be repurposed, effectively doubling the available channels.
