1. Brand and Product Line:
-
Woodward: A highly respected and major global manufacturer of control systems for aerospace and industrial applications. They are especially known for controls in turbines, engines, and power generation.
-
Micronet Simplex: This refers to the control system family. “Micronet” is Woodward’s legacy networked control platform. “Simplex” indicates this is a system designed for less critical applications where a single (non-redundant) controller is sufficient, as opposed to a “Duplex” redundant system for high availability.
2. Part Number:
-
5466-5026: This is the specific part number for this module. It’s crucial for identifying the exact product for ordering, replacement, or finding technical documentation.
3. Module Type: High-Density Analog Module
This is the most important part of the description:
-
Module: It is a card that plugs into a rack or chassis (like a 5466-855 Simplex I/O Chassis) to form part of a larger control system.
-
Analog: It deals with analog signals. Unlike digital signals (which are simply ON/OFF, 1/0), analog signals are variable and represent a range of values (like pressure, temperature, flow rate, or voltage).
-
Input: This module is designed to receive signals from analog field devices (sensors or transmitters) and convert them into a digital value that the main Micronet controller can understand and process.
-
High-Density: This means the module has a large number of input channels on a single card. Instead of a module that handles only 4 or 8 signals, a high-density module might handle 16 or more, saving space in the control rack.
4. Typical Function and Use Cases:
-
Purpose: To interface between analog sensors and the central control system.
-
Example Sensors it Connects To:
-
Temperature: RTDs (Resistance Temperature Detectors) or Thermocouples.
-
Pressure: Pressure transmitters (4-20 mA signal is very common).
-
Flow: Flow meters.
-
Level: Level transmitters.
-
Valve Position: Feedback from a valve.
-
-
Common Industries:
-
Power Generation (Gas Turbines, Steam Turbines)
-
Oil & Gas
-
Marine Propulsion
-
Industrial Compression and Pumping
-
5. Key Characteristics (from its datasheet):
-
Channels: 16 single-ended or 8 differential analog input channels.
-
Signal Types: It is typically configurable (via software or jumpers) to accept different analog signal types, most commonly:
-
4 to 20 mA (milliamps) – the most common industrial analog signal.
-
0 to 10 VDC (Volts DC).
-
1 to 5 VDC.
-
It may also support direct connection to certain RTDs or thermocouples.
-
-
Resolution: High resolution (e.g., 16-bit) for accurate measurement.
-
Isolation: Provides electrical isolation between the field wiring and the control system to protect against power surges and noise.
