Honeywell 51202921-200 Analog Input Module In Stock

HONEYWELL 51202921-200 is a fail-safe analog input module with four 0-2 V analog input channels. It is part of the Honeywell TDC2000 series of distributed control systems (DCS).

Specifications:

1. Input range: 0-2 V
2. Input impedance: 10 MΩ
3. Resolution: 12 bits
4. Accuracy: ±0.1% FS
5. Conversion time: 1 ms
6. Operating temperature range: -40 to 85 °C
7. Supply voltage: 24 V DC

Key Features:

1. Fail-safe design: The module has a redundant input stage and a microcontroller that continuously monitors the inputs for faults. If a fault is detected, the module will output a safe value to the DCS.
2. High input impedance: This allows the module to be connected to high-impedance sensors, such as thermocouples and RTDs.
3. Parallel connection: Two 51202921-200 modules can be connected in parallel to double the number of input channels.
4. Diagnostics: The module provides a variety of diagnostic features, such as input range checking, broken wire detection, and sensor shorting detection.

Applications:

1. Measuring the temperature of a chemical reactor
2. Monitoring the pressure in a hydraulic system
3. Controlling the flow rate of a liquid
4. Measuring the level of a liquid in a tank
