1. Introduction
The Frequency Transducer is a DIN Rail / Wall mounted 43.5
X 65.5mm Transducer.
Input Frequency and Output Voltage/Current are displayed
on LCD and indicated by LED’s.
Frequency Transducer can be
configured and programmed at
site for the following : Input
parameters (i.e start, end and
elbow value of Input) and Output
Parameters(i.e as Voltage or as
Current and start, end and elbow
value of outputs).
The front panel has two push
buttons through which the user may scroll through the
output screens and configure the product.
1.1 LED Indication
The Frequency Transducer is used to measure and convert
Frequency input into proportional DC current or voltage
output signal.

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 of the
Output screen by pressing the“ Up key” or by pressing “
Down key”.

3. Programming
3.1 Programming via Front LCD & Two keys
The following sections comprise step by step procedures for
configuring the Frequency Transducer for individual user
requirements.
To access the set-up screens press and hold the “ Down”
and “ Up” keys simultaneously for 5 seconds. This will take
the User into the Password Protection Entry Stage .
3.1.1. Password Protection
3.1.1.1 Password Verification
Password protection can be enabled to prevent
unauthorised access to set-up screens, by default password
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
Frequency transducer using optional PRKAB601
Adapter.
3.3. Programming Via optional RS485(MODBUS)
communication port.
