900B01-0001 Honeywell Analog Output Module

Product Description

The 900B01-0001 is a high-performance, isolated analog output module designed for the Honeywell HC900 Control System. It provides four independent channels, enabling precise control of field devices such as actuators, control valves, and Variable Frequency Drives (VFDs). With robust isolation and flexible signal options, this module is ideal for deterministic process control in demanding industrial environments.

Each channel is galvanically isolated from the backplane and other channels, protecting the controller logic from ground loops and electrical interference. Its wide operating temperature and humidity ranges ensure reliable performance in both indoor control rooms and harsh remote process enclosures.

Technical Specifications

Application Scenarios

• Modulating Valve Control: Delivering precise 4–20 mA signals to actuators in steam or liquid flow loops.

• Motor Speed Regulation: Controlling pump or fan speeds via VFDs using 0–10 V signals.

• HVAC Automation: Managing industrial dampers and heating elements in large-scale facilities.

• Boiler Management: Regulating fuel-to-air ratios through analog actuator positioning.

Frequently Asked Questions

Does the 900B01-0001 support current (4–20 mA) output?
Yes. It supports both current loops (4–20 mA, 0–20 mA) and voltage outputs (0–10 VDC), making it a universal analog output module for the HC900.

What terminal block is required for this module?
The module typically uses a 20-terminal block (Part Number 900TE1-0001) for field wiring. This is usually ordered separately or as part of an I/O kit.
