Short description:
The configurable isolation amplifiers convert, amplify, filter and electrically
isolate analog standard signals. The devices have a 3-way isolation with a
2.5kV test voltage. The 857-411 Isolation Amplifier provides electrical isolation
between the 0(4) - 20mA input and the 0(4) - 20mA output analog current
signals. The 857-412 Isolation Amplifier provides electrical isolation between
the 0(2) - 10V input and the 0(2) - 10V output analog voltage signals.
The device is supplied with 24VDC, which can be quickly and cost-effectively
commoned via lateral, push-in type jumper bars.
A green LED on the front panel indicates normal operation. The isolation
amplifiers meet the requirements for safe isolation of input, output and supply
circuits with 2.5kV test voltage according to EN 61140.
