Honeywell 900A01-0202 Universal Analog Input Module

The Honeywell 900A01-0202 is an advanced Universal Analog Input (AI) module with the following key features:

Multiple Input Types: Supports up to 8 user-configurable inputs, including thermocouples (T/C), RTDs, resistance, voltage (V), millivolts (mV), milliamps (mA), and slidewire, all with point-to-point isolation.
Isolation and Noise Rejection: Offers galvanic isolation of 400 VDC point-to-point and 1K VDC to logic. Provides high noise rejection (Series Mode >60dB, Common Mode >130dB at 120VAC).
Diagnostics and LED Indicators:
- Green LED for scanning
- Amber LED for forced input channels
- Red LED for diagnostic alerts
Temperature and Sensor Failures: Monitors thermocouple inputs for maintenance needs before sensor failure and detects faulty thermocouples.
Configurable and Accurate: Field calibration is possible, and the factory calibration accuracy is ±0.1% of the range. The cold junction accuracy is ±0.7 °C.
Failsafe Support: Allows user-selectable failsafe values for each channel, with configurable behavior for input failure (upscale, downscale, or defined value).
A/D Conversion: Utilizes 15-bit A/D converters with a 500ms update rate for each module, ensuring efficient data conversion without latency.
Over-range Detection: Supports over-range limits and burnout detection for various input types.

Input Types: Thermocouple, RTD, mV, V, mA, Slidewire
Accuracy: Factory-calibrated with a ±0.1% of range accuracy and ±0.7 °C cold junction accuracy.
Temperature Effect: ±0.01% of full scale per degree Celsius.
Dimensions: 137mm H x 35.6mm W (5.4″ H * 1.4″ W)
