The PREMIUM protection relay INT69 PYF Diagnose connects pumps, protection functions and the digital world. Simple networking is possible with the help of the integrated Modbus interface. The device monitors the motor temperature, the bearing temperature, leakage, vibration, voltage and current. The integrated power measurement is suitable for a frequency converter. A relay for alarm and warning ensures the necessary operational safety.

The INT69 PYF Diagnose with Modbus interface and power measurement is a universal and versatile protection relay. The following inputs and outputs are available for monitoring electrical components:
| Terminals | Inputs and outputs |
| L/L+, N/L- | Supply voltage |
| T1, T2 | Motor temperature (PTC, Pt100, Pt1000, bimetal, external relay contact) |
| T3, T4 | Temperature 1 (PTC, Pt100, Pt1000) |
| T5, T6 | Temperature 2 (PTC, Pt100, Pt1000) |
| E+, E- | Leakage (resistance measurement) |
| SC1, SC2 | Switching input (float switch, external reset) |
| I+, I- | Analog input 0/4-20mA |
| FE | Functional ground |
| L1, L2, L3 | Phase monitoring with phase sequence, phase failure, phase asymmetry, undervoltage and overvoltage |
| S1, S2 | Current transformer INT185 |
| 11, 14, 12 | Alarm relay |
| 21, 24, 22 | Warning relay |
| COM, D1, D0, COM | RS485, Modbus RTU |
Cosφ, service interval, switching frequency, short circuit and interruption of the sensors can also be monitored. Consumed apparent, active and reactive power is determined and in the protection relay and active and reactive energy is counted. Parametrization enables protection functions and response settings to be adapted flexibly to suit the application.
The INT69 PYF Diagnose saves operating and fault data in a non-volatile memory. This data can be read out and evaluated for diagnostic purposes. Parameterization and diagnostics are possible via the built-in diagnostic port (DP) using the INTspector app and with separately available accessories. This protection relay device is used primarily for the protection of pumps and agitators. The INT185 current transformer is also required for the full range of functions.
