The device has a 3way 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 available that can also be configured using software. Item No. Pack.
