ABB UNS 0863A-P V1 HIEE305082R0001 Digital I/O Card

ABB UNS 0863A-P V1 HIEE305082R0001 Digital I/O Card

Functional Description

The I/O interface UNS 0863 provides the connection between the binary process signals and the signal

processing device UNS 1860, which is part of the entire converter unit. The AC measured values, 3x U and 1x

I from the first machine transformer set are picked up by the AC actual value measurement interface UNS

0862 at connector X11 and fed to channel I. If only one machine transformer set is provided for a 2-channel

system, the same measured values are also fed to channel II; the jumper TWIN must be set to position N for

this purpose. 

If two machine transformer sets are provided in a 2-channel system, a second AC actual value measurement

interface UNS 0862 is connected to connector X12. This means that both channels receive independent AC

measurement signals; the jumper TWIN must be set to position Y for this purpose. 

A total of 4 analog outputs are provided. With the option PSS signal transformer UNS 0869 V2, two outputs

are used for excitation current and machine power. The two others can be parameterised and are available

for the output of signals for customer use. In 2-channel systems, the signals are taken from the currently

active channel. 2 parameterisable analog inputs are provided, e.g. for reference values of superimposed

regulators.
