PR120/D-M Communication Module
PR120/D-M communication module is the solution for connecting Emax to a Modbus network,
allowing the remote supervision and control of the circuit-breaker.
It is suitable for PR122/P and PR123/P trip units. As for PR120/V this module can be added at any
time to the protection trip unit and its presence is automatically recognized. When ordered
separately from the circuit-breakers it is supplied complete of all the accessories needed for its
installation, such as precabled auxiliary switches and cables for signalling the curcuit-breaker
status (springs, position inserted). Refer to circuit diagram page 8/12 for details about connections. The module can be powered by means of a 24V DC auxiliary supply.
The list of available functions can be found on page 4/42.
It is provided with three LEDS on the front side:
– Power LED
– Rx/Tx LEDs
PR120/D-BT Wireless Communication Module
PR120/D-BT is the innovative wireless communication module, based on Bluetooth standard. It
allows the communication among the PR122/P and PR123/P Protection trip units and a PDA or
a Notebook with a Bluetooth port. This device is dedicated to the use with SD-Pocket application (see in the following the features of this application).
The module can be powered by means of te 24V DC auxiliary supply or by means of PR030/B
battery unit.
It is provided with four LEDS on the front side:
– Power LED
– Rx/Tx LEDs
– Bluetooth LED, showing the activity of Bluetooth communication
PR120/D-BT can be connected at any time to the protection trip unit.
BT030 Communication unit
BT030 is a device to be connected on Test connector of PR121/P, PR122/P and PR123/P. It
allows Bluetooth communication among the Protection trip unit and a PDA or a Notebook with
a Bluetooth port. BT030 can also be used with Tmax circuit breakers equipped with PR222DS/
PD. This device is dedicated to the use with SD-Pocket application.
BT030 can provide the power supply needed to energize itself and the protection trip unit by
means of a Li-ion rechargeable battery.
PR030/B power supply unit
This accessory, always supplied with the PR122 and PR123 range of trip units, makes it
possible to read and configure the parameters of the unit whatever the status of the circuitbreaker (open-closed, in test isolated or racked-in position, with/without auxiliary power supply).
PR030/B is also needed for reading trip data if the trip occurred more than 48 hours earlier and
the trip unit was no longer powered.
An internal electronic circuit supplies the unit for approximately 3 consecutive hours for the
sole purpose of reading and configuring data.
In relation to the amount of use, battery life decreases if the SACE PR030/B accessory is also
used to perform the Trip test & Auto test.
Interface from front of HMI030 panel
This accessory, suitable for all protection trip units, is designed for the installation on the front
side of the switchboard. It consists of a graphic display where all the measurements and
alarms/events of the trip unit are shown. The user can browse the measurements by using the
navigation pushbuttons, similarly to PR122/P and PR123/P. Thanks to the high precision level,
the same of the protection trip units, the device can replace the traditional instrumentation,
without the need for current/voltage transformers. The unit requires only a 24 V DC power
supply. In fact HMI030 is connected directly to the protection trip unit via a serial line.
