JUMPFLEX® measuring transducer
Isolating amplifier, configurable with zero/span adjustment

Brief description:
The configurable isolating amplifier converts analogue standard signals and amplifies and galvanically isolates the analogue standard signals from one another. The device has a 3-way isolation with a test voltage of 2.5 kV. Using DIP switches accessible on the side, the following signals can be configured in the input and output:
0 ... 10 V, 2 ... 10 V, 0 ... 20 mA, 4 ... 20 mA, 0 ... 5 V and 1 ... 5 V.
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 isolating amplifier meets the requirements of safe isolation as per EN 61140 with a test voltage of 2.5 kV between input/output/supply.
