Short description:
The 857-402 Universal Isolation Amplifier converts, amplifies and electrically
isolates analog standard signals. The device has a 3-way isolation with a 2.5kV
test voltage. In addition to standard signals, both unipolar and bipolar signals
(± 10V, ± 20mA) up to 200V and 100mA can be set on the input side via DIP
switches, which are accessible from the side of the housing. The analog output
also supports standard unipolar and bipolar signals. Measurement range swit-
ching is calibrated. The device is supplied with 24VDC, which can be efficiently
commoned using lateral push-in type jumper bars. A green LED on the front pa-
nel indicates normal operation.
The isolation amplifier provides safe isolation of input, output and supply circuits
with 2.5kV test voltage according to EN 61140.
A self-resetting fuse effectively protects the current input against overload.
The fuse automatically resets when the overload is removed.
