A green LED on the plify, filter and electrically isolate analog standard signals. The device has a 3- front panel indicates normal operation. The isolation amplifier meets the re- way isolation with a 2.5kV test voltage. DIP switches accessible from the side quirements for safe isolation of input, output and supply circuits with 2.5kV test can be used to configure the signals in both input and output. voltage according to EN 61140. 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. Pack.
