Introduction
The IT210 isa universal interface using with incremental measuring systems.
The device allows the solution of the following problems:
• Level conversion (RS-422, HTL single ended, HTL differential, TTL and vice versa)
• Division of two-track A / B pulses with adjustable ratio 1: 1 to 1: 4096
• Division of the Z pulse with adjustable ratio 1: 1 to 1: 256
• External HTL signals for various functions
• Implementation between the two types of representations for the direction of rotation
(A/B 90 °, A/B Dir and vice versa, Division possible)
• Start /stop functionality via external ZERO_A signal
All settings are made on the DILL switches on the housing. The device consists of a compact
housing with screw terminals and can be mounted on a DIN rail.Block diagram

Electrical Connections
The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).
DC Power Supply
The device is supplied with a DC voltage between 9 ... 30 VDC via terminals 1 and 2 of X1. The
current consumption depends on the level ofthe supply voltage and the settings and is approx.
35 mA without load from the sensor supply and additional on the extracted encoder current at
the auxiliary voltageoutput.
All GND terminals are internally interconnected.
Auxiliary Voltage Output
At terminal 8 and 9 of X4 the auxiliary voltage as encoder / sensor supply is +5.5 VDC and can
be charged with max. 250 mA.

Page 9 / 23
Incremental Inputs A, /A, B, /B, Z, /Z
At terminal 2 ... 7 of X4, 3 pulse inputs are available for HTL / TTL / RS422 signals. The unused
inputsmust beopen (HTL single ended vs. HTL differential) or terminated (unused Ztrack in RS-
422 or HTL differentialformat).

Smart in Control –[e-mail]
Page 10 / 23
Please note that all input and output signals refer to the same common
potential (GND) which at the same time is also the minus potential of the
power supply.
Atanytime, the totaltransmissioncharacteristicsofencoder, external
components and capacity of the cable must ensure proper signals at the
input terminals ofthe unit, with respect tothe levels, the shape and the
phase displacement A/B.
Control Inputs
Two control inputs with HTL PNP characteristics are available at terminals 2 and 3 of X2 and
are used for resetting the internal dividers
Unconnected control inputs are always “LOW”.
All inputs are designed to receive impulses from an electronic impulse source.
Notice for mechanical switching contacts:
When exceptionally mechanical contacts are used,pleaseconnectan external capacitor
between GND (-) and the corresponding input (+). A capacity of10 µF will reduce the input
frequency to
20 Hz and miscounting due to contact bouncing will be eliminated.
Pulse output
Depending on the DIL switch setting, the pulses are available in HTL or RS-422 format at the
outputs of screw terminal X3 and are independent of the used format. The height of the pulse
levelatthepush-pulloutputsintheHTLsettingcorrespondsapproximately totheinputvoltage
at the supply input X1.

Page 11 / 23
Error Ausgang
An HTL error signal (input error, only with RS-422 or HTL differential) isavailable at the X3
screw terminal 1. (Error = low).
The error is triggered by a line fault (short circuit or line break) by the input lines A, / A, B, / B or
Z, / Z. (Test mode OFF, DIL2 / 2 = OFF.
The DIL switch DIL3 (right, 3-pin) can be used to select the corresponding channel. If the DIL3 /
1 contact is set to OFF, no errors are evaluated on the A, / A line, DIL3 / 2 refers to the line B, /
B and DIL3 / 3 to the line Z, / Z.
An error can only be detected in RS-422 or HTL differential format, all other formats will not
trigger an error.
LED

If the A/B pulse have to be switched unchanged from the input to the output (no division, no
change in length and position), then the DIL switch position listed below must be chosen. A
level conversion is only possible if the input mode (A/B 90 ° or A/B dir) corresponds to the

Case 1: Input A/B 90°, Output A/B Dir
DIL1/6 = OFF, DIL1/7 = ON with A/B Divider setting: DIL5, 6 = all OFF
If the direction of the A/B 90 ° signal changes at the input, a change takes place at the BOUT
output signal. (A/B dir). There is no division.
Case 2: Input A/B Dir, Output A/B 90°
DIL1/6 = ON, DIL1/7 = OFF with A/B Divider setting: DIL5, 6 = all OFF

Setting to zero the A/B divider with ZERO_A Signal
The divider will only be reset in the zero phase of the output signals AOUT and BOUT and will
remain as long as the signal is attached. This prevents the miscounting of subsequent circuits.
This function can only be applied to A/B 90°, it is independent of the divider ratio.

Location and width of the Z pulse
If the DIL switch DIL4 of the Z divider is completely set to OFF, the Z Pulse is forwarded from
the input directly to the output (see level conversion Z Puls).
Allpictures inthissection assumethattheA/Bdividerissetto8.TheZPulse isdivided
accordingtoitsdivider (additionally DIL2/1 on OFF,ZINisused, Zdividers not complete on
OFF).
Depending on the length or location of the Z Pulses input and through the synchronization to
the input or output signals, the Z pulse at the output can fluctuate around an input or output
period (not with DIL1/5 = DIL1/4 = ON).

The pulse width at the output corresponds to ¼ period of pulse width at the

In this operation mode, only division ratios may be used, which together with the A/B divisor
deliver clear and completely results. A division with rest causes that the Z pulse at the output
can fluctuate around an input or output period.
Example:
Ifatanencoderwith 1000 pulses theA/B deviderweresetto3and at the same time the Z
Pulse divider were set to 2, then the Z Pulse at the output would have to appear after 666,666
pulses, which is not physically possible.
