2 - Identification
Device can be identified through the
ordering code
and the
serial number
printed on the label applied to its body. Information is listed in the delivery
document too. Please always quote the ordering code and the serial number
when reaching Lika Electronic s.r.l. for purchasing spare parts or needing
assistance. For any information on the technical characteristics of the product,
refer to the technical catalogue.
3 - Introduction
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.
The impulse input side provides channels A, B and also the inverted lines /A, /B
which should be used with TTL / RS-422 input signals. The unit can count and
convert the following formats to analogue and serial information:
a. Increasing / decreasing count with quadrature input (A/B, 90

). The
polarity of the analogue output and the sign of the serial data depend
on the sign of the actual counting result.
b. Single channel impulses on channel A. Input B sets the counting
direction and therefore also the polarity of the output (LOW = negative,
HIGH = positive).
Please observe:

Open NPN inputs are HIGH;

Open PNP inputs are LOW;

Open RS-422 inputs may cause problems, therefore please set
unused inputs to HTL by means of the DIL switches.
c. Dual count of fully independent events on channels A and B, where the
output signal represents the sum or the difference of both counts.
The definitions for “zero analogue output” and “full scale analogue output” can
be set over the full counting range of ±8 decades (-99 999 999 to +99 999 999).
