The S-DIAS counter input module FC 021 has 2 digital RS422 inputs,
2 digital TTL inputs and 2 digital HTL inputs. The module provides the
option to configure 2 counter inputs or one incremental encoder input.
The RS422, TTL or HTL inputs can thereby be optionally used for the
counter function. Parallel to the inputs, the module also provides the
actual status of all digital inputs (2x RS422, 2x TTL and 2x HTL). The
TTL and HTL inputs are galvanically separated on the S-DIAS bus.
The sensor supply connected to X3 is also galvanically separated on
the S-DIAS bus and is available at both connectors X1 and X2.
