Description
The Woodward 8237-1104 is a high-precision analog input module in the MicroNet series of control systems, designed specifically for industrial process control and turbine systems. It reliably acquires critical operating parameters. The module supports standard 4–20 mA current signals, features 12–16 bit resolution and ±0.1% typical accuracy across the entire range, and is equipped with ±0.02%/°C temperature drift compensation to maintain accurate acquisition over a wide temperature range. The 8237-1104 employs a high-isolation design (channel isolation ≤1500 VDC) to ensure system immunity and security, with power consumption below 5 W, making it suitable for industrial equipment operating continuously for extended periods.

This rack-mount card design allows direct installation in Woodward MicroNet or compatible control racks, providing stable signal acquisition and reliable data transmission to ensure accurate control data for gas turbines, steam turbines, compressors, and large industrial equipment. Whether for new system deployment, existing system expansion, or spare parts replacement of legacy systems, the 8237-1104 provides a high-precision, low-maintenance-cost solution, widely used in power plants, power equipment, petrochemical processes, and industrial automation, providing reliable support and stable operation for critical industrial control systems.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does the module store control logic?
The 8237-1104 is used only for signal acquisition and does not store control strategies. All logic is managed by a MicroNet CPU (such as the 5200/RTN).
What input signal types are supported?
The module supports standard 4–20 mA current inputs, suitable for industrial sensor and process control signal acquisition.
What are the module's accuracy and resolution?
The 8237-1104 offers 12–16 bit resolution, with typical accuracy of ±0.1% of full scale at 25°C and temperature drift of ±0.02% per °C, ensuring high-precision signal acquisition.
What are the operating voltage and power consumption?
The module has a rated voltage of 24 VDC and a power consumption of ≤ 5 W, suitable for standard industrial control cabinet power supply configurations.
What is the module's channel isolation?
The module offers channel isolation up to 1500 VDC, effectively improving system security and interference immunity.
What is the operating temperature and humidity range?
The module can operate in environments ranging from -40°C to +85°C (-40°F to +185°F) and is suitable for non-condensing humidity conditions of 0–95%.
What are the installation methods and compatibility?
The 8237-1104 is a rack-mount card module and must be installed in a Woodward MicroNet or compatible control rack. It is generally compatible with older MicroNet systems.
Is it discontinued?
Some versions are listed as obsolete but can still be used as critical spare parts. Please refer to the official recommended alternative models (such as 5466-5026 or 8200-1102).
Is it repairable?
Modules can be repaired and refurbished through Woodward authorized service centers or professional industrial control repair shops to extend their service life.
