(1) Values are volts D.C. (except resistances)
(2) It is NOT recommended that the user runs their SDM-SIO1A at maximum ratings for
extended periods of time
(3) Assuming a worst case 3 KΩ load
(4) It is not recommended that the user allows such low input voltages as there will be an
increased chance that external noise may cause errors in the incoming data
The SDM-SIO1A has been tested and shown to comply with IEC 61326. The
device incorporates transient and surge protection that is designed to meet
IEC61000-4-5, level 4, providing the device is adequately grounded.
