Spectrum Controls 1769 CompactLogix I/O modules are available with optional Conformal Coating (*K) to help protect the circuit board by providing a layer of protection against contaminants and humidity in harsh, corrosive environments.
Conformal coating is the process of spraying a non-conducting substance, an insulator, onto a device or component to help protect it from moisture, fungus, dust, corrosion, abrasion and other environmental stresses. It is a thin film that “conforms” to the varied profiles of an assembly.
Conformal coating offers protection of circuitry from moisture, fungus, dust and corrosion caused by highly-polluted atmospheres. It also offers improved product life cycle when exposure to corrosive environment is present. It helps maintain long-term surface insulation resistance, ensuring operational integrity of the assembly.
1769 CompactLogix™ I/O
Who should use Conformal Coated products: - Water/Wastewater - Mining - Pulp and Paper - Metal - Food and Beverage Processing - Tire and Rubber - Oil & Gas - Marine
Why use Conformal Coated products: - Protects components from environmental factors - Reduce degradation due to environmental hazards - Minimize environmental stress - Eliminate the need for complex enclosures - Prevent the board from corroding - Cost Savings: Components Last Longer
Users around the world have realized the benefits of HART communications by gaining quick and easy visibility to their devices in the field. The HART Protocol is popular due to the huge installation base of 4–20 mA systems throughout the world.
The HART Communication Protocol (Highway Addressable Remote Transducer) communicates over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems. HART is widely used in process and instrumentation systems ranging from small automation applications up to highly sophisticated industrial applications.
Spectrum Controls offers HART for Allen-Bradley 1734 POINT I/O and 1769 CompactLogix I/O control systems.
