Performance Parameters
- Operating Temperature: 0°C to 60°C
- Storage Temperature: -40°C to 85°C
- Power Supply: 24 VDC via backplane
- Protection Rating: IP20
Material Composition
Constructed with durable, flame-retardant industrial plastics and conformal-coated electronics for maximum environmental protection.
Structural Characteristics
Single-width 200 Series FBM form factor. Interfaces with the backplane via precision pins and connects to field devices through a specific Terminal Assembly.
Operating Principle
Receives digital control commands from the controller over the redundant Module Fieldbus. It isolates the command and drives the corresponding output channel to energize or de-energize the connected field load.
Installation Requirements
Mount on a compatible 200 Series baseplate. Ensure the control cabinet is well-ventilated and properly grounded. Verify that the field load voltage and current ratings do not exceed module specifications.
Usage Precautions
Ensure the field load voltage matches the module’s specified output range. Always observe standard ESD precautions during handling. Never exceed the maximum current rating per channel or per module.
