RTD Trip Amp DAT5024R2

General Description.

The DAT5024R2 is a DIN Rail mount RTD Trip Amplifier. It accept signals from Resistors and RTD's. The Threshold 1 is programmed as high alarm, while, by dip-switches, it is possible to set the Threshold 2 either as high or low alarm. The trip level of each threshold can be adjusted by the potentiometers and checked by the test-points located on the front of the device. It is possible to adjust the values of the hysteresis level and delay time by potentiometers .

The DAT5024R2 has 2000 Vac isolation between the RTD inputs and the relay contacts.
The DAT5024R2 has isolations of 2000 Vac between the power supply and the RTD inputs.
The RTD input is isolated from the relay contacts by 1500Vac.
The DAT5024 is in compliance with the standard 89/336/EEC on the Electromagnetic Compatibility. It is housed in a plastic enclosure of 20.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
