Channel-to-Channel Isolation and Field Signal Processing

The FC-TSDI-16115 processes 115 V AC or 115 V DC field signals through a 16-channel safe input conversion structure. In addition, each input channel uses galvanic isolation to separate field circuits and reduce electrical interaction between channels.

The module accepts both active and passive digital input configurations. Therefore, it supports flexible field device connection methods while maintaining defined input threshold characteristics. The input circuit uses non-inductive impedance design for industrial switching signal measurement.

For Honeywell safety and process control architectures, this FTA design supports discrete signal termination between field wiring and the control system interface. Furthermore, the isolated input arrangement helps maintain signal separation during multi-channel digital monitoring.
