SCADAPack 470i Protection Levels

[R.B]

Hello Everyone,

I am selecting Surge Protection Devices for the SCADAPack 470i, but I could not found enough information in the manuals.

I am wondering if anyone has information on the protection levels of the SCADAPack 470i inputs (Power, Analog, Digital...).

I checked the manual Chapter 16 - Specifications (page 148)

The only information is in Chapter 16.7 - Communications (page 154).

On this interface the Protection level is 2 kV.

I am looking for the same information for all interfaces, more precisely for power, analog and digital.

Thank you in advance.

Hello R.B,

The certifications that the SCADAPack 47x | 47xi meet are documented in the datasheet. I've attached a recent copy, though datasheets can be found on our website by navigating to:

-> Products -> Industrial Automation

-> Telemetry & Remote SCADA

-> SCADAPack 47x | 47xi -> Documents

Dear Joel,

Thank you for your reply.

Sorry I do not have access to this standards, I tried to check online on different sources.

From my understanding the protection can varies depending on the test level.

Here is a summary of what I found.

Standard	Type of Surge/Transient	Min Test Voltage (kV)
IEC 61000-4-2	Electrostatic Discharge (ESD)	±2 kV (contact & air)
IEC 61000-4-4	Electrical Fast Transient (EFT/Burst)	0.5 kV (power/signal lines)
IEC 61000-4-5	Surge (Lightning, switching surge)	0.5 kV
IEC 61000-4-18	Damped Oscillatory Transient	~0.5 kV
IEC 60255-21	Surge (protection relay test)	~1 kV

On my project we are only going to use Power, Analog and Digital.

If I apply the information according to the standard and take the worst case scenario here his what I got.

Standard	Power	Analog	Digital
IEC 61000-4-2	2kV	2kV	2kV
IEC 61000-4-4	0.5kV	0.5kV	0.5kV
IEC 61000-4-5	0.5kV	0.5kV	0.5kV
IEC 61000-4-18	0.5kV	0.5kV	0.5kV
IEC 60255-21	1kV	1kV	1kV

If this is correct I think this is OK.

Best regards,

R.B
