# IOMOD FPI User Manual ### 1. Introduction IOMod FPI stands for Fault Passage Indicator. It is an inteligent electronic device (IED) used for short circuit and ground fault indication with direction detection. It measures three phases of AC voltage and current amplitudes and phase shifts. The faults are detected by applying certain algorithms along with the measured data. The measured and calculated values are transmitted to the host system via communication protocol **Modbus RTU, IEC 60870-5-101 or IEC 60870-5-103**. #### 1.1 Features - Directional fault detection for all network types; - Earth fault detection; - 50 Instantaneous overcurrent detection; - 50N Neutral instantaneous overcurrent detection; - 51/67 Phase directional overcurrent detection; - 67N Neutral directional overcurrent detection; - 27 Undervoltage detection (with VT or voltage sensors); - 59 Overvoltage detection (with VT or voltage sensors); - 59N Neutral overvoltage detection / permanent earth fault (with VT or voltage sensors); - 81HBL2 Inrush blocking for selected protections; - **2 settings groups;** - Integration into Elseta mini RTU; - Measurements of RMS values for currents, phase, and phase-to-phase voltages. - Additional measurements of: - Frequency; - Active, reactive, and apparent power; - Neutral voltage, neutral current; - Power factor; - Phase angle; - Analog inputs measurement in 16-bit resolution - 3x low-power (LoPo) current measuring inputs (225 mV) or 3 x 1 A/5 A CT with the adapter. - 3x low-power (LoPo) voltage measuring inputs (3.25 V/√3) or 3 x 100 V/400 V VT with the adapter. - Frequency acquisition (Nominal frequencies: 50 and 60 Hz; Frequency range: 45–65 Hz). - Communication port: RS485 - Communication over Modbus RTU, IEC 60870-5-101 and IEC 60870-5-103 protocols. #### 1.2 Block diagram [](https://wiki.elseta.com/uploads/images/gallery/2024-11/image-1730793469738.png) Fig. 1.2.1.
