SIEMENS 3UF7114-1BA01-0 Current/Voltage Measuring Module V2

Overview

The SIEMENS 3UF7114-1BA01-0 is a V2 generation current and voltage measuring module designed for Siemens SIMOCODE pro motor management system. The SIEMENS 3UF7114-1BA01-0 adopts busbar connection design and covers measuring current range from 63 A to 630 A, with voltage measurement up to 690 V AC. It captures true RMS electrical parameters including current, voltage, active power, power factor and frequency, and transmits measured data to the matched SIMOCODE pro V base unit. The SIEMENS 3UF7114-1BA01-0 is widely used as spare replacement for motor control centers in chemical, power and water treatment plants.

Features

The SIEMENS 3UF7114-1BA01-0 supports high-precision TRMS measurement for distorted industrial power signals. It integrates internal voltage divider circuit and does not need external current transformers for the rated range. The SIEMENS 3UF7114-1BA01-0 works with SIMOCODE pro V PB, pro V MR, pro V PN and pro V EIP base units. It carries global hazardous area certifications and can be deployed in explosive zone applications. The SIEMENS 3UF7114-1BA01-0 has 145 mm overall width and standard busbar mounting interface for simple installation and direct replacement.

Specs

Device Type: Current/Voltage measuring module V2 Model: SIEMENS 3UF7114-1BA01-0 Current Range: 63 A to 630 A Max Voltage: 690 V AC Measurement Method: True RMS Mounting: Busbar connection Width: 145 mm Compatible Unit: SIMOCODE pro V series base unit Protection Grade: IP00 Application: MCC motor feeder, SIMOCODE pro motor management, power parameter monitoring

Principle

The SIEMENS 3UF7114-1BA01-0 samples three-phase current and voltage signals directly from the main busbar. The internal signal conditioning circuit converts primary power signals into low-level digital measurement data. It sends all electrical values to the SIMOCODE pro base unit through the internal module bus for motor protection, energy calculation and communication upload to DCS or PLC. The module continuously monitors the integrity of the main circuit. When abnormal overload or wiring fault occurs, the SIEMENS 3UF7114-1BA01-0 feeds abnormal measurement data back to the base unit for protection trigger and alarm output.

Applications

The SIEMENS 3UF7114-1BA01-0 is used for heavy motor feeder monitoring in motor control centers of power generation, chemical and mining industries. It serves power consumption statistics and motor protection signal acquisition for large pump and fan control loops. The SIEMENS 3UF7114-1BA01-0 applies to spare stock and emergency repair of existing SIMOCODE pro motor management cabinets. It also supports new MCC cabinet construction and field upgrade of SIMOCODE measurement loops.
