Certificate of conformity (CoC) IECEx IBE 14.0023 X SSI clock rate 50 kHz ... 2 MHz
Category I M2 Ex d I/IIC T4 - T6 Mb Monoflop time ) 15 µs
IECEx IEC 60079-0:2011; Note: if clock starts cycling within monoflop time a second data transfer starts
IEC 60079-1:2007 with the same data. If clock starts cycling after monoflop time, the data transfer
starts with updated values. The update rate depends on clock speed, data
length and monoflop time.

The encoder can be set to zero at any position by means of a HIGH signal on
the SET input. Other preset values can be factory-programmed.
DIR input The SET input has a signal delay time of approximately 1 ms. Once the SET
A HIGH signal switches the direction of rotation from the default CW to CCW. function has been triggered, the encoder requires an internal processing time
The reverse function can also be factory-programmed. of approximately 15 ms before the new position data can be read.
If DIR is reversed when the device is already switched on, this will be
interpreted as an error. The status output switches to LOW.
Status output
Output driver open collector, internal pull-up
Power-ON time resistor 22 kOhm
After Power-ON, the device requires a time of approximately 150 ms before Permissible load max. 20 mA
valid data can be read. Signal level HIGH +V
LOW < 1 V
Active at LOW
The status output serves to display various alarm or error messages.
The status output is HIGH (open collector with internal pull-up 22 kOhm) in
normaloperation.
