HONEYWELL 900A16-0101 16-Channel High-Level Analog Input Module

Description

HONEYWELL 900A16-0101 16-Channel High-Level Analog Input Module

Product Overview

The Honeywell 900A16-0101 is a high-density, 16-channel high-level analog input module engineered for the ControlEdge HC900 hybrid control and safety system.

It provides precise data acquisition for high-level process variables, accepting standard voltage (e.g., 0–5V, 0–10V, 1–5V) and current loop signals (e.g., 4–20mA, 0–20mA). With point-to-point solid-state galvanic isolation and fast A/D conversion, this module is designed for continuous, high-reliability operation in harsh industrial environments.

Technical Specifications

Key Advantages

• High Channel Density: Accommodates 16 analog input channels in a single 1.4-inch-wide module slot, maximizing rack space efficiency in switchboards and cabinets.
• Point-to-Point Isolation: Solid-state switching provides galvanic point-to-point isolation, preventing ground loops between process transmitters and protecting adjacent system hardware.
• G3 Conformal Coating: Standardized coating against corrosive atmospheres (such as airborne hydrogen sulfide and chlorine), making it ideal for harsh chemical or wastewater environments.
• Exceptional Accuracy & Stability: Features 15-bit A/D resolution with low temperature drift (±0.01%/°C), delivering precise measurements for critical loops.
• Flexible Termination Options: Works seamlessly with Honeywell DIN-rail mounted Remote Terminal Panels (RTPs) and pre-wired cable assemblies to cut wiring labor and field commissioning times.

Important Usage & Installation Precautions

• Current Shunt Resistor Requirement: When measuring current loop inputs (4–20 mA), ensure the corresponding 250 Ω precision shunt resistors are correctly installed across the input terminals as specified in the HC900 hardware manual.
• Field Wiring Routing: Use shielded twisted-pair cables for signal wiring. Route analog signal lines separately from high-voltage AC cables and motor drives to preserve the >90 dB common-mode noise rejection.
• Hot-Swapping Rules: Refer to system software guidelines before inserting or removing the module. Ensure the rack address keying and slot assignments match the HC900 Designer configuration.
• Terminal Grounding: Connect cable shields strictly to the designated chassis/earth ground bar at one end only to prevent ground loop noise from degrading analog readings.
• Environmental Enclosure: Install inside a minimum NEMA 12 / IP54 rated control panel to keep ambient operating temperatures within 0°C to 60°C and maintain non-condensing humidity levels (10% to 90%).

Applications

• Process Loop Monitoring: Ideal for centralizing measurements of temperature, pressure, flow rate, and liquid level transmitters across industrial processing plants.
• Furnaces, Kilns & Boilers: High-density feedback collection for multi-zone thermal profile tracking and combustion control.
• Chemical & Pharmaceutical Manufacturing: Real-time data logging and batch process monitoring in reactors, autoclaves, and drying units.
• Water & Wastewater Treatment: Continuous measurement of tank levels, flow rates, pump head pressures, and chemical feed dosages.
• Oil, Gas & Energy Systems: Pipeline pressure/flow telemetry, compressor station telemetry, and power generation monitoring.
