What Is SCADA? Supervisory Control Without Replacing the PLC
SCADA sits above PLCs and RTUs: it acquires field data, alarms operators, and issues supervisory commands across plants and remote assets—without replacing local deterministic control.

Designed for seamless integration within industrial process control systems, the Honeywell MC-TDIY22 functions as a high-density, 32-channel Digital Input Field Termination Assembly (FTA). This module serves as the critical physical interface between field-level discrete sensors and the Honeywell Process Manager I/O (PMIO) subsystem, enabling reliable system control and real-time data acquisition.
Engineered to handle 24 VDC digital input signals, the MC-TDIY22 conditions, isolates, and routes electrical signals from field equipment to control processors. Its robust construction ensures stable operation under demanding thermal and electrical conditions, making it suitable for continuous-duty industrial applications.
