Product Overview

The Honeywell 900A01-0102 is a high-performance 8-channel universal analog input module designed for the ControlEdge HC900 and 900 Series automation platforms. This module provides precise measurement of process variables including temperature, pressure, flow, and level with exceptional accuracy and reliability. The 900A01-0102 supports a wide range of input types including thermocouples (types J, K, T, E, R, S, B, N), RTDs (100 Ω Pt, 200 Ω Pt, 100 Ω Ni), millivolt signals (±100 mV, ±50 mV, ±25 mV), and user-configurable milliamp or voltage inputs. It features channel-to-channel and channel-to-system isolation rated at 500 V, ensuring signal integrity in demanding industrial environments.

With 16-bit analog-to-digital conversion and ±0.1% full-scale accuracy, the 900A01-0102 delivers high-resolution process measurement critical for precise control strategies. The module includes hot-swap capability, allowing insertion or removal without powering down the system, and LED indicators for module and channel status.
