INT69 PYF Diagnose PREMIUM

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.
