Short description:
The software-configurable 857-401 Isolation Amplifier is used to convert, am-
plify, filter and electrically isolate analog standard signals. The device has a 3-
way isolation with a 2.5kV test voltage. DIP switches accessible from the side
can be used to configure the signals in both input and output.
In addition to standard signals, bipolar (± 10V, ± 20mA) and 0 to 30V signals
can also be set on the input side. The analog output supports standard unipolar
signals. In addition, the devices can be configured using FDT/DTM software.
The software offers additional setting options such as special input and output
signal combinations with intermediate values or inversion of the analog output.
Measurement range switching is calibrated. A digital switching output is avai-
lable that can also be configured using software.
The device is supplied with 24VDC, which can be commoned using lateral
push-in type jumper bars in a quick and cost effective way. A green LED on the
front panel indicates normal operation. The isolation amplifier meets the re-
quirements for safe isolation of input, output and supply circuits with 2.5kV test
voltage according to EN 61140.
