Product Overview – Honeywell 900B01-0301 Analog Output Module

• Honeywell 900B01-0301 is a 4-channel analog output module for precise current control.
• Each channel delivers isolated current output signals.
• Outputs scale freely within the 0–21.8 mA operating range.
• Designed for stable process control and automation systems.
• Status LEDs allow fast visual diagnostics.
• Failsafe operation ensures predictable plant behavior.

Core Functional Highlights

• Four fully isolated analog outputs.
• User adjustable output span per channel.
• 0.1% full-scale accuracy improves control precision.
• Synchronous update with controller scan cycle.
• Integrated diagnostics monitoring.
• Non-volatile calibration memory prevents data loss.
