IF51
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
IF51 is the small, low-cost yet high-performing converter for industrial
applications suitable for use in applications where the information delivered by
a sensor or encoder fitted with SSI interface needs to be converted into an
analogue signal or into a serial RS-232/RS-485 data format.
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.
Applicable encoders and sensors
Single-turn or multi-turn absolute encoders and all similar sensors using a
standard SSI interface (6 to 25 bits of resolution with binary or Gray code)
can be connected to IF51. The unit can operate in either Master mode (clock
signal is generated by IF51 unit) or in Slave mode (clock signal is generated
by a remote device).
Remark about encoder resolution
The unit provides settings for the standard resolutions of 13 bits, 21 bits and
25 bits. As a general rule, for sensors with other resolutions you can use the
next higher setting (i.e. set the unit to 21 bits when you use a 16-bit sensor).
Depending on the brand and specification of the encoder, in some cases it
may be necessary to blank out the surplus bits by using the bit blanking
function described later, see “Hint for the use of the bit blanking function”
on page 46. Anyway, generally the unit works properly even without special
bit blanking.
