PISA11

PISA11-Series

Output over-current protection

Electronically limited

Class of protection

III

IEC 61140

Degree of protection

IP 20

EN/IEC 60529

Penetration protection

> 2.5mm in diameter

E.g. screws, small parts

Over-temperature protection

Not included

Reverse polarity protection;

input voltage

Not included

Make sure that the input voltage polarity is correct

before applying the input voltage.

Internal input fuse

Not included

The relay contact and the ON/OFF signal input are floating and have no ohmic connection to the input or output

voltage. Type and factory tests are conducted by the manufacturer.

The creepage and clearance distances between relay contacts, the ON/OFF signal input and input/output voltage are

1.3mm.

The following dielectric strength tests were conducted:

Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the

appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all input and

output terminals together as well as all signal poles before conducting the tests. When testing, set the cut-off current

settings to the value in the table above.
