Frequently Asked Questions

What type of power supply is required for this device?

The device requires a rated voltage of 18 to 32 V DC, which can be supplied through a Power Rail or terminals 17+ and 18-.

Can this device be used with a Pt100 sensor?

Yes, the device is designed to work with Pt100 sensors, with a measurement range of 10 to 390 Ohms and a measuring current of approximately 2 mA.

What are the output specifications of this device?

The device has two outputs, Output I and Output II, each with terminals for limit values. They can handle a contact loading of 253 V AC, 2 A, with a cos ϕ greater than 0.6 and have a mechanical life of 2 x 10^7 switching cycles.

How does ambient temperature influence the device's performance?

The device's switching point is influenced by ambient temperature at a rate of 0.015% per Kelvin of the measuring range, and the display is influenced at a rate of 0.01% per Kelvin of the measuring range.

What is the function of the LC-display on the device?

The LC-display on the device shows the resistance of the Pt100 directly in Ohms, and by using the Pt100-value table, you can determine the corresponding measurement temperature.
