Yokogawa AAI543-H53S1 Analog Output Module

Output Signal: 4 to 20 mA current signal, compatible with most industrial actuators and 

transmitters.

Channel Capacity: 16 isolated channels, enabling independent signal transmission without cross-

interference.

Isolation Performance: Channel-to-channel and channel-to-chassis isolation, ensuring signal 

integrity in harsh electromagnetic environments.

Power Consumption: Max 230 mA (5 V DC) and 540 mA (24 V DC), energy-efficient for large-scale 

system deployment.

Load Compatibility: Supports external load resistance ≥200 Ω (critical for stable operation in high-

temperature environments: 60–70 °C).

Redundancy Support: Compatible with dual-redundant configurations, with a factor of 25 for 

standard response and 29 for fast response, meeting high-availability system requirements.

Operating Temperature: 0 to 60 °C (standard) ; optional -20 to 70 °C for extreme conditions (with 

installation restrictions).

Environmental Resilience: Complies with ANSI/ISA S71.04 G2 (standard) and G3 (option) for 

corrosive gas resistance, suitable for harsh industrial sites.

EMC Compliance: Withstands electric field (3 V/m, 26 MHz–2.7 GHz) and magnetic field (30 A/m 

AC, 400 A/m DC) interference, ensuring stable operation in noisy environments.

Isolated channels prevent signal crosstalk and ground loop interference, critical for precision control in complex industrial systems (e.g., process automation, power plants).

Enhances system safety by isolating field devices from the control unit, reducing the risk of damage 

from voltage surges.

Signal Connection Options: Compatible with pressure clamp terminals (single: ATA4S; dual-

redundant: ATA4D), dedicated cables (KS1), and MIL connector cables for diverse wiring scenarios.

Node Compatibility: Works with ESB Bus Node Units (ANB10), Optical ESB Bus Node Units 

(ANB11), and Field Control Units (AFV30/AFV40/AFV10), supporting seamless integration into 

Yokogawa’s CENTUM VP system.

Dual-Redundant Support: Enables hot-swap in redundant configurations, minimizing downtime for 

mission-critical applications.

Operates stably in wide temperature and humidity ranges (5–95% RH, non-condensing) and resists 

vibration (2.0 m/s², 14–100 Hz) and shock, suitable for on-site installation in harsh conditions.

Complies with global safety and EMC standards (CSA, CE Marking, EAC Marking, RCM), facilitating 

international project deployment.
