Bachmann EAS102 Absolute Encoder Interface Module

Type EAS102 M100 modules make it possible to evaluate

up to 2 absolute encoders. SSI (Synchronous Serial Interface)

is used as the communication protocol.

The EAS102 offers the openness of an extensively configurable

SSI protocol. Furthermore, a parity check and

the evaluation of transmitted special purpose bits are supported.

The counting direction can be defined via the DIR

output. Referencing is initiated via the SET output. Digitally

transmitted encoder errors can be detected via a separate

input. If the actual position is reaching a configured comparison

value, module-to-module communication enables

a digital output to be switched at the adjacent module

without any time loss. An encoder supply directly via the

module terminals enables a complete and fast SSI encoder

connection directly via the connector panel of the EAS102

module.
