The PS2801-4-F3-A(NL) is a multi-channel solid-state relay (SSR) manufactured by CEL (California Eastern Laboratories). It features four independent channels, allowing for simultaneous switching of multiple signals with galvanic isolation. The 'F3' likely denotes a specific tape and reel packaging for automated assembly, 'A' may indicate a particular pinout or internal configuration, and '(NL)' signifies a lead-free version, compliant with RoHS standards.

Applications

• Industrial Automation: Used in programmable logic controllers (PLCs) and distributed control systems (DCS) for switching multiple inputs/outputs (I/O).
• Data Acquisition Systems: Employed in data loggers and measurement equipment for isolated channel selection and switching.
• Automatic Test Equipment (ATE): Utilized in test fixtures and automated test systems for switching multiple test points.
• Multiplexers: Can be configured as a multiplexer for signal routing and selection in various electronic systems.
• Process Control: Integrated into process control systems for controlling multiple actuators and sensors with isolation.

Features

• Multi-Channel Configuration: Provides four independent SSR channels in a single package.
• High Isolation Voltage: Offers strong galvanic isolation between the input and output circuits for each channel.
• Low On-Resistance: Minimizes voltage drop and power dissipation across the switch.
• Fast Switching Speed: Enables rapid switching operations for improved system response.
• Compact Package: Reduces board space requirements and simplifies circuit design compared to using discrete SSRs.
