Technical Overview

The ATB5S-00 S2 is a compact digital input (binary) module designed for Yokogawa industrial automation systems. This Style 2 (S2) version provides reliable acquisition of 24 VDC ON/OFF and pulse signals, converting field-side discrete states into real-time control system data.

Optimized for high-speed response and strong noise immunity, the ATB5S-00 S2 is well suited for monitoring critical process statuses in CENTUM-based DCS architectures, particularly where space-efficient, high-density I/O is required.

Technical FAQ

What does the “S2” designation mean?
“S2” refers to Style 2 hardware, incorporating updated electronic components for improved durability and EMI resistance compared to earlier versions.

Can the ATB5S-00 S2 accept AC signals?
No. The module is strictly rated for 24 VDC inputs. Applying AC voltage may damage the internal opto-isolation circuitry.

Are individual channels isolated?
The module provides isolation between the field side and system bus. Individual channels typically share a common return (COM); refer to the applicable wiring diagram for terminal configuration.
