Details: K23-SSI/USB/25B-C
Function
The K23-SSI/USB/25B-C is a small and inexpensive, but extremely powerful signal converter for industrial applications, where SSI telegrams from sensors or encoders are converted into parallel signals.
The device is contained in a compact housing for rail mounting.
The device features
-
screw terminals
-
a USB connection
-
a 25-pin Sub-D socket
-
3 user-configurable digital control inputs
Applicable encoders and sensors
Encoders and all comparable sensors with SSI interface (10 ... 32 bit binary or Gray code), either in leading mode (the device generates the clock signal itself), or in guided mode (the device switches to an existing clock signal).
Incremental input signals are processed in frequency converter mode or counter mode. In start-stop mode, transonic or magnetostrictive displacement sensors can be connected.
