Binary input module with 16 channels for single indication, dual indication, digital gauges and pulse

counters

– Resolution 1ms

– Process voltage: 24…. 24…60 V DC / 110…125 V DC . 125 V DC

– LED signal per input

– Common return signal per 8 inputs

The binary input unit performs the following processing functions for different types of signals:

– Digital filtering to suppress contact bounce

– Suppression of process-induced oscillating signals

– Intermediate input status for validity check and double indication of suppression

– Consistency check of all channels assigned to digital measured values or step position information

– Summing of incremental pulses to form a combined total in a 31-bit resolution register.

– The combined total is copied into a freeze register to save the data.

The module provides a data buffer for storing up to 50 event messages (including timestamps) in

chronological order.

Events are stored in chronological order and designated for transmission to the communication unit

(CMU) During initialization and operation, the module performs a series of tests. If a fault occurs, it is

reported to the CMU.

All fault conditions affecting the module’s functionality are indicated as common fault signals by means

of red LEDs.

Module faults are detected by the communication unit.
