Honeywell 900A01-0102 Analog Input Module 8 Point

Product Overview

The Honeywell 900A01-0102 is a Universal Analog Input Module providing 8 isolated channels for the Honeywell ControlEdge HC900 platform. This versatile module accepts multiple signal types including thermocouples (TC), RTDs, voltage, current (4-20 mA), millivolt, and slidewire inputs, making it ideal for comprehensive process monitoring applications. With 16-bit A/D resolution, ±0.1% accuracy, and galvanic isolation per channel, it delivers precise, reliable measurement of temperature, pressure, flow, and level variables.

FAQ

Q: What is the difference between 900A01-0102 and 900A01-0202?
A> 900A01-0202 is a later revision with similar functionality. Both support universal analog inputs. Verify software compatibility when mixing revisions.

Q: Can all 8 channels be configured differently?
A> Yes. Each channel is independently configurable for any supported input type via ControlEdge Builder software.

Q: Is HART protocol supported?
A> The 900A01-0102 does not natively support HART. For HART-enabled analog inputs, consider the 900U01-0100 Universal I/O Module.

Selection Tips

• Use 900A01-0102 when multiple analog signal types (TC, RTD, mA, V) are needed in one module
• For high-density voltage/current only (16 CH), use 900A16-0101/0103
• Verify sensor wiring requirements (2-wire vs. 3-wire RTD) before installation
• Consider 900U01-0100 Universal I/O for mixed AI/AO/DI/DO applications
