JUMPFLEX® measuring transducer
Isolating amplifier, permanently set for current signals or voltage signals

Brief description:
The pre-configured isolating amplifiers convert analogue standard signals and amplify, filter and galvanically isolate the analogue standard signals from one another.
The devices have a 3-way isolation with a test voltage of 2.5 kV. Isolating amplifier 857-411 isolates analogue current signals in the range of 0(4) ... 20 mA in the input to 0(4) ... 20 mA in the output.
Isolating amplifier 857-412 isolates analogue voltage signals in the range of 0(2) ... 10 V in the input to 0(2) ... 10 V in the output. 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 amplifiers meet the requirements of safe isolation as per EN 61140 with a test voltage of 2.5 kV between input/output/supply.
