JUMPFLEX® measuring transducer
Temperature-measuring transducer for thermocouples type J, K

Brief description:
The temperature-measuring transducer for thermocouples offers connection options for themocouples of types J and K. The thermocouple temperature-measuring transformer 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.
