Physical Dimensions and Mounting
This module measures 130 mm in height, 30 mm in width, and 100 mm in depth. The unit weighs approximately 0.32 kg. It mounts directly onto a DIN rail within the system cabinet. The front panel includes 16 LED indicators for all channels. These LEDs show input states and output conditions clearly.
Electrical Interface and Field Wiring
A 37-pin D-sub connector provides the primary interface for all field wiring connections. The input section accepts dry contact or powered sensor signals on each channel. The output section drives 24 VDC loads with sourcing configuration. Each output includes short-circuit and overcurrent protection. Field devices like limit switches connect to inputs while solenoid valves connect to outputs.
Performance and Operational Characteristics
The ATA4D-00 S2 scans inputs and updates outputs within a single control cycle. It includes input filtering for reliable noise rejection in industrial environments. The module provides output state feedback for verifying commanded states. This feedback ensures outputs match the control system’s requests. Moreover, built-in diagnostics monitor both input and output channels for faults.
Installation and System Integration
You can install this module in any available slot within the Yokogawa CENTUM chassis. The backplane automatically handles address assignment and power distribution. Always verify load currents stay within per-channel ratings. For high-current loads, use external interposing relays for switching.
Environmental Compliance
This module carries CE marking and UL recognition for industrial use. It also complies with RoHS and WEEE environmental directives. The conformal coating provides protection against moisture and dust.
