857-800 Temperature-measuring transducer - Pt100/Pt200/Pt500/Pt1000

JUMPFLEX® measuring transducer Temperature-measuring transducer for Pt100, Pt200, Pt500 and Pt1000 and resistances 0 ... 1 kOhm; 0 ... 4.5 kOhm

Brief description: The temperature-measuring transducer for Pt sensors offers connection options for Pt100, Pt200, Pt500 and Pt1000 sensors in 2, 3 and 4-conductor connection systems. Furthermore, resistances in the range 0 ...1 k , or 0 ... 4.5 k can be registered on the input. The PT100 temperature-measuring transducer converts the temperature signal on the output side into an analogue standard signal. This signal can be 0 ... 20 mA, 4 ... 20 mA, 0 ... 10 V, 2 ... 10 V, 0 ... 5 V, 1 ... 5 V, 0 ... 10 mA and 2 ... 10 mA. The device has 3-way galvanic isolation with a test voltage of 2.5 kV. The devices can be configured via the DIP switches accessible on the side of the housing. The measurement ranges are switched in a calibrated form. The supply voltage for the device, which can be bridged quickly and cost-effectively via side push-in type jumper bars, is 24 V DC. A green LED on the front of the device signals that it is in operation. The temperature-measuring transformer meets the requirements of safe isolation as per EN 61140 with a test voltage of 2.5 kV between input/output/supply.
