IF50
Description
IF50 is the small, low-cost yet high-performing converter for industrial
applications suitable for use in installations where incremental counting of
positions or events must be converted to either analogue format or serial data.
The unit has been designed as a compact module with 12 screw terminals and a
9-position SUB-D connector (female). The housing is suitable for standard DIN
rail mounting.
