INT69 YF Diagnose EXTENDED

The solid all-round protective relay with a large number of sensor inputs for monitoring motor temperature, bearing temperature, leakage, vibration and voltage. The INT69 YF Diagnose EXTENDED differs from the STANDARD version because it provides an additional input for vibration measurement and a warning relay. Protective functions and behavior can be flexibly adjusted to the application through parameterization. The pump protection relays are particularly suitable for monitoring pumps, pump systems and submersible mixers in the water and wastewater industry.

The INT69 YF Diagnose 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)
T3, T4 Temperature 1 (PTC, Pt100, Pt1000)
T5, T6 Temperature 2 (PTC, Pt100, Pt1000)
E1+, E1- Leakage 1 (resistance measurement, switching input)
E2+, E2- Leakage 2 (resistance measurement, switching input)
I+, I- Analog input 0/4-20 mA
FE Functional ground
L1, L2, L3 Phase monitoring with phase sequence, phase failure, phase asymmetry, undervoltage and overvoltage
11, 14, 12 Alarm relay
21, 24, 22 Warning relay

Parametrization enables protection functions and response settings to be adapted flexibly to suit the application. The INT69 YF Diagnose saves operating and fault data in a nonvolatile 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.
