Technical description

The binary spacer module reserves digital addresses in the WAGO buscoupler.

The number of inputs or outputs can be selected by two DIP switches. 2, 4, 6 or 8 bits are possible (1, 2, 3 or 4-channel modules). A third DIP Switch selects inputs or outputs.

The configuration is indicated by means of 3 LEDs, which are lit, even if there is no voltage applied.

The binary spacer module also works as a 24 V supply module. Power must be connected to supply the modules following the binary spacer.

The DIP switches and LEDs are used as follows. When the switch is OFF the LED is also OFF (dark LED symbol). When the switch is ON the LED lightens (light LED symbol).

Technical description

This technical description is only valid for hardware and software versions X X X X 2 B 0 2----. The product series number is printed on the right side of the module.

The operational mode of the module is factory preset to a 24 bit absolute encoder Gray code signal transmitted at 125kHz.

The following description is preliminary and is applicable to the factory configuration.

The SSI Interface can operate with all WAGO-I/O-SYSTEM bus-couplers (except for the economy type).

The use of this module in conjunction with a SSI encoder provides direct positional information rather than the type of data resulting from incremental type encoders.

Absolute encoders are comprised of several data disks to generate a data word which is unique through out the 360 degrees of rotation. The data format is a modified binary pattern in either Gray code or Dualcode.
