1. Introduction
The Current Transducer is a DIN Rail/wall mounted 43.5 X
65.5mm Transducer.
Input
Current and Output Voltage / Current is displayed on LCD
and indicated by LED’s.
The Current Transducer is used to measure and convert AC
Current input into proportional DC current or voltage output
signal. Output signal generated is proportional to the True
RMS (upto 15th Harmonic) of the input Current.
Current Transducer can be
configured and programmed at
site for the following CT Primary
,CT Secondary (1A to 5A) , Input
Characteristics (i.e start, end and
elbow value of Input) and Output
parameters (i.e as Voltage or as
Current and Characteristics of
start, end and elbow value of
outputs).

The front panel has two keys through which the user may
scroll through the output screens and configure the product.

2. Input and Output screens
In normal operation the user is presented with display test
screen followed by version screen to one of the output
screen. These screens may be scrolled through one at a
time Output 1 or Output 2 by pressing the “ Up key” or
“ Down key”.

3. Programming
3.1 Programming via Front LCD & Two keys
The following sections comprise step by step procedures for
configuring the Current Transducer for individual user
requirements.
To access the set-up screens press & hold the“ down” &
“ up” keys simultaneously for 5 seconds. This will take the
User into the Password Protection Entry Stage .
Programming of transducer can be done in three ways :
3.1. Programming Via Front LCD & two keys.
3.2. Programming Via Programming port available at front of
Current transducer using option PRKAB60 Adapter.
3.3. Programming Via optional RS485(MODBUS)
communication port.
