Safety Instructions and Responsibility General Safety Instructions This operation manual is a significant component of the unit and includes important rules and hints about the installation, function and usage.
Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.
Compatibility Hint The main differences between the IT210 and the respective predecessor model IT251 are listed below: IT251 Housing Input Input characteristics Frequency Output Encoder supply Temperature MTBF Supply Input type A/B-divider Z-divider Zero pulse length It210_02a_oi_e.docx / Jan-20 251 RS422/DSUB HTL/clamps RS422/HTL Single Max. 300kHz RS422/DSUB HTL/clamps Parallel outputs 5.5V/130mA 0..45° 55,4a 18..
Introduction The IT210 is a universal interface using with incremental measuring systems.
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 of the 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 voltage output. All GND terminals are internally interconnected.
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 inputs must be open (HTL single ended vs. HTL differential) or terminated (unused Z track in RS422 or HTL differential format). Wiring of the incremental inputs: RS422 HTL DIFFERENTIAL HTL PNP It210_02a_oi_e.
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, please connect an external capacitor between GND (-) and the corresponding input (+).
Error Ausgang An HTL error signal (input error, only with RS-422 or HTL differential) is available 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.
Input and output configuration Changes in the settings on the DIL switches will only be taken over by the device after the supply voltage has been switched on again!

Level converter A/B Pulse (A/B Divider: All OFF) 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 output mode. (DIL1/6 = DIL1/7).
Adjustable divider A/B Setting the A/B Divider (at A/B Dir to A/B 90°) The division ratio for the A/B pulses is set at the DIL switches DIL5 and DIL6. The switch positions use a binary code like shown in the subsequent list. (DIL1/6 = ON, DIL1/7 = OFF).
Setting the A/B divider (for all other modes) The division ratio for the A/B pulses is set at the DIL switches DIL5 and DIL6. The switch positions use a binary code like shown in the subsequent list. (DIL1/6 = OFF, DIL1/7 = X).
Example: Input A/B 90°, output A/B 90 ° with A/B division 1:3 (setting DIL6, 5: OFF ON OFF Example: Input A/B 90°, output A/B 90 ° with A/B division 1:3 (setting DIL6, 5: OFF ON OFF It210_02a_oi_e.
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. If there is a high signal at ZERO_A the A/B divider is reset and has the starting state AOUT = BOUT = Low. The divider is in a defined state.
Adjustable divider Z Pegel conversion Z Puls (Z Divider: all OFF) If the Z 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.
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). All pictures in this section assume that the A/B divider is set to 8. The Z Pulse is divided according to its divider (additionally DIL2/1 on OFF, ZIN is used, Z dividers not complete on OFF).
DIL1 Front Narrow Z pulse (1/4 output-periode) 8-pole (Only applicable to output signals A/B 90°, DIL1/7 = OFF) 4 5 ON OFF The pulse width at the output corresponds to ¼ period of pulse width at the output. 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.
Automatic generation of a Z pulse If the DIL switch DIL2/1 is set to ON, a Z pulse can be automatically generated. The Z input is ineffective and does not need to be connected (Z divider not completely set on OFF). DIL1 Front Narrow Z puls e (1/4 output- or input-period) 8-pole 4 5 OFF ON The Z pulse is generated from the input signal A/B. Each input period generates one count for the Z divider.
