The device can be ordered with integrated overvoltage protection for diverse approvals:
Order code for "Accessory mounted", option NA "Overvoltage protection"
Input voltage range
Resistance per channel
DC sparkover voltage
Trip surge voltage
Capacitance at 1 MHz
Nominal discharge current
(8/20 μs)
Temperature range
1) The voltage is reduced by the amount of the internal resistance I
Depending on the temperature class, restrictions apply to the ambient temperature
for device versions with overvoltage protection .
For detailed information on the temperature tables, see the separate document
entitled "Safety Instructions" (XA) for the device.
