Description
The ControlByWeb® X-20S is a powerful expansion module designed to scale your control system by adding six heavy-duty relays and six optically isolated digital inputs. It is specifically engineered to interface seamlessly with the X-400™ and X-600M™ controllers via a simple ribbon cable connection, making it an ideal choice for facility automation, pump and fan control, and industrial equipment monitoring.
Built for demanding environments, the X-20S features robust Form-C (SPDT) relays capable of high-current switching, ensuring reliable performance for motors, solenoid valves, and lighting arrays. The optically isolated digital inputs provide secure status monitoring by electrically separating incoming signals from your control circuits. With its durable PVC enclosure and wide operating temperature range, the X-20S offers the reliability required for scalable industrial deployments.
Key Features
- Scalable I/O Capacity: Easily expand your system by daisy-chaining modules to support complex automation needs.
- Heavy-Duty Switching: Features 6 high-current SPDT (Form C) relays (15A, 277VAC/30VDC) suitable for motors and valves.
- Reliable Monitoring: 6 optically isolated digital inputs protect your controller while monitoring limit switches, sensors, or security devices.
- Advanced Input Logic: Digital inputs support sophisticated functions including state monitoring, cycle counting, frequency measurement, and accumulated “ON” time tracking.
- Industrial Design: Housed in a flame-rated (UL94 V1) enclosure with screw-terminal connectivity for secure, vibration-resistant wiring.
- Wide Power Compatibility: Flexible operation with 9–28 VDC (24V recommended).
