ABB SACE Flex Interfaces are a range of 10 modular DIN rail electronic devices, thought up
for signaling and transmitting information between circuit-breakers and other devices, such
as actuators, communication networks and measuring instruments.
Thanks to this function, it is possible to make simple and economic the applications like:
• electrical signalling of events, alarms and circuit-breaker trips;
• transmission of electrical measurements to switchboard instruments, or remote control, by
means of 4-20 mA signals;
• additional protection of the plant based on measurements of external values, such as pressure and temperature;
• non-priority load control.
According to the methods of connection to the moulded-case and air circuit-breakers, the
devices in the Flex Interface family, are identified in:
• Accessory Devices (ADs) which are connected to the electronic trip unit by means of an
interfacing unit.
• System Devices (SDs) which are connected by means of an external communication bus to
data managing unit (like a Personal Computer, a PLC or a SCADA).
• Local Device (LD) which is connected directly to the trip unit.
To complete the Flex Interface range, the HMI030 switchboard multimeter is also available,
which allows display of all the measurements managed by the trip unit it is connected to.
The dimensions of all Flex Interface devices are four modular units, with simple and immediate cabling, and require an auxiliary power supply at 24 V DC to function.
The Accesory Devices family (ADs) has 3 modular devices AD030DO, AD030AO and AD030MI,
able to add analog and/or digital output and input to the circuit breaker’s trip unit connected to
the interface MM030.
MM030 is able to mange the data exchange with all the Emax trip units.
• AD030 DO: the module periodically receives signals from the trip unit, updates the eight
digital outputs and then the associated LEDs;
• AD030 AO: the unit is able to convert the measurement signals which come from the trip unit
into 4-20 mA electrical signals, such as currents, voltages, power, peak factor, energy and
frequency. Four analog outputs are available;
• AD030 MI: acquiring signals coming from the external field, the device can convert these
into two analog and two digital inputs to be sent to the electronic trip unit in order to obtain
protections and signalling.
• MM030: this device is always necessary when the Accessory Devices are present. This
module is the interface between the circuit-breaker trip unit and the other ADs.
The System Devices are modular devices connected to an external communication bus, to
which a device, such as a Personal Computer, PLC or SCADA is connected. It is possible to
acquire data in real time with digital and/or analog input and to use some digital and/or analog
inputs to activate electro-mechanical devices or to visualize electrical measures remotely.
There are 5 devices:
• SD030 DX: the main device in the System Devices family. It manages five digital inputs and
three digital outputs. It allows remote supervision and activation of switch-disconnectors
and circuit-breakers without the communication function by means of a SCADA or PLC.
• SD030 DO: the module receives data from a PLC and consequently activates the eight
digital outputs.
• SD030 DI: the module receives data from the external field and transmits them to a main
system connected by means of a system bus. Up to eight digital input signals are available.
