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.
Is there any electrical isolation provided in this device?
Yes, the device provides safe electrical isolation according to EN 50020 between input/output, input/power supply, and output/power supply, with a voltage peak value of 375 V.
What type of protection does this device offer in hazardous areas?
The device offers [EEx ia] type of protection for explosion groups IIB and IIC, with specific parameters for external capacitance and inductance provided in the technical documentation.
How can I adjust the switch points or limit values?
Switch points or limit values can be adjusted using the potentiometers T1 and T2 on the device. Additionally, hysteresis for each switch point can be set using potentiometers 1 and 2.
What are the ambient operating conditions for this device?
The device can operate in ambient temperatures ranging from -20 to 60 degrees Celsius, and it has a protection degree of IP20.
How does the device handle lead breakage monitoring?
Lead breakage monitoring can be turned on or off using the DIP switch S2.3. If lead breakage occurs in the input circuit, the output relays will be deactivated.
