Honeywell 900B01‑0301 4‑Channel Analog Output Module for Industrial ControlEdge/HC900 Systems

Applications

The 900B01‑0301 excels in applications where reliable analog current output is needed for device control:

• Industrial process loops (pressure, flow, level, temperature)
• Control of proportional valves and actuators
• Feedback loops in manufacturing automation
• Distributed logic control with analog interfacing
• Retrofits and expansions of legacy HC900 installations

Its isolated outputs and precise resolution ensure clean, stable analog control even in noisy plant environments.

Advantages

• High Precision Outputs – ±0.1 % full scale ensures accurate analog signals
• Isolated Channels – Reduces noise and interference between loops
• Compact Footprint – Fits standard HC900 I/O racks efficiently
• Built‑In Diagnostics – Supports reliable commissioning and maintenance
• Flexible Output Span – 0–20 mA loop support across diverse devices
• Industry‑Proven Design – Long‑standing field use in automation systems
