IFM Modus Interface for System

IFM - Modbus communication interface - is required for connecting Masterpact or PowerPact circuit breakers to the Modbus serial network whenever the circuit breaker has a ULP port (Universal Logic Plug). The port is available on BCM ULP for Masterpact range and BSCM module for the PowerPact range.

Once connected to IFM, the circuit breaker is considered as a slave by the Modbus master. Its electrical values, alarm status, open/close signals can be monitored or controlled by a Programmable Logic Controller or any other system.

ULP Port

Two RJ45 sockets, internal parallel wiring.

• Connection of a single circuit breaker.

• An ULP line terminator, IO module, or FDM121 display unit must be connected to the second RJ45 ULP socket.

The RJ45 sockets deliver 24 Vdc from the Modbus socket.

Built-in test function, for checking the correct connection to the circuit breaker and FDM121 display unit.

Modbus Slave Port

• Modbus Serial RJ45 port - RJ45 connector provides fast and accurate wiring.

• Lateral socket, for DIN rail stackable connector.

Both top and lateral sockets are internally parallel wired.

• Multiple IFM can be stacked, thus sharing a common power supply and Modbus line without individual wiring.

• On the front face:

  • Modbus address setting (1 to 99): 2 coded rotary switches

  • Modbus locking pad: enables or disable the circuit breaker remote control and modification of IFM parameters.

• Self adjusting communication format (Baud rate, parity).

24 Vdc Power Supply

• Screw clamp terminal block

• High electrical insulation between Modbus and 24 Vdc connectors + separated lines provides improved communication robustness.
