Honeywell 900A16-0101 Analog Input Hi Level Module

Product Overview

The Honeywell 900A16-0101 is a High-Level Analog Input Module providing 16 isolated channels for voltage and current signal acquisition in the Honeywell ControlEdge HC900 system. Designed for high-density process monitoring, this module accepts ±10V voltage and 4-20 mA current inputs with 15-bit A/D resolution and ±0.1% accuracy. Point-to-point galvanic isolation and solid-state switching ensure reliable operation in noisy industrial environments.

FAQ

Q: What is the difference between 900A16-0101 and 900A16-0103?
A> 900A16-0103 is a later revision with enhanced specifications. Both are 16-channel high-level analog input modules. Verify software compatibility.

Q: Can this module measure thermocouples or RTDs?
A> No. The 900A16 is for high-level voltage/current signals only. For TC/RTD inputs, use 900A01-0102 Universal Analog Input Module.

Q: What is the maximum source resistance for current inputs?
A> The module presents a 250 Ω burden. Ensure transmitter output voltage is sufficient to drive 4-20 mA through this resistance plus wiring.

Selection Tips

• Use 900A16-0101 for high-density voltage/current monitoring (16 CH vs. 8 CH on 900A01)
• For mixed signal types (TC, RTD, mA, V), use 900A01-0102 instead
• Verify scan time requirements: 100 ms for 900A16 vs. 500 ms for 900A01
