KFU8-GUT-1.D

What type of device is this?

This is a 1-channel temperature converter with trip values. It acts as a signal conditioner, converting input signals from temperature sensors, potentiometers, or voltage sources into a proportional analog current output while also providing relay trip outputs.

What input types can it accept?

The unit can accept RTD inputs such as Pt100, Pt500, Pt1000, Ni100, and Ni1000; thermocouple inputs including types B, E, J, K, L, N, R, S, and T; potentiometer inputs from 0.8 kΩ to 20 kΩ; and voltage inputs including 0 to 10 V, 2 to 10 V, 0 to 1 V, and -100 to 100 mV.

What output signals does it provide?

It provides two relay contact outputs and one analog current output. The current output can be configured for 0 to 20 mA or 4 to 20 mA operation, making it suitable for process monitoring and control applications.

What power supply range does it use?

The KFU8-GUT-1.D operates with a wide supply range of 20 to 90 V DC or 48 to 253 V AC, allowing it to be used in a variety of industrial control panel environments.

Can it be used with thermocouples requiring cold junction compensation?

Yes. For thermocouple applications, a removable K-CJC terminal block can be used when internal cold junction compensation is required. External cold junction compensation is also specified for this unit.

Does it detect sensor faults?

Yes. The device includes measuring circuit monitoring features such as sensor breakage detection and, for RTD inputs, sensor short-circuit detection. It also provides line fault and sensor burnout detection functions.

What are the relay contact ratings?

The relay outputs are rated for 250 V AC at 2 A with a power factor of cos φ ≥ 0.7, or 40 V DC at 2 A. The mechanical relay life is specified as 50,000,000 switching cycles.

How is it mounted in a control cabinet?

The unit is designed for mounting on a 35 mm DIN rail in accordance with EN 60715. Its dimensions are 40 x 119 x 115 mm, using a C3 housing style.

What ambient temperature range is specified?

The specified ambient operating temperature range is -20 to 60 °C, or -4 to 140 °F.

What level of enclosure protection does it have?

The unit has an IP20 degree of protection, which is typical for components installed inside industrial electrical cabinets or protected control enclosures.

What is the analog output load limit?

The analog current output has a maximum load of 650 Ω and an open-loop voltage of up to 24 V DC.

Can it be used with redundant thermocouple inputs?

Yes. The device can accept a redundant thermocouple input of the same type. If one thermocouple lead break is detected, the value from the second thermocouple can be used for further calculation.
