Core Functions & Adaptability
Precision Current Output

Working in closed-loop current control with the VAOC module, the system delivers high-accuracy analog output suitable for servo valves, actuators, and regulating valves, ensuring stable and precise control performance.

Simplex-Dedicated Design

Optimized for simplex control architectures, the module communicates exclusively with VAOC boards, reducing system complexity and simplifying configuration, commissioning, and maintenance.

Coordinated System Operation

Must be used in conjunction with the Mark VI power supply module (e.g., IS200PSVOH1A) and the VAOC module (e.g., IS200VAOCH1A) to ensure stable power delivery, signal integrity, and reliable system operation.
