Description
The ControlByWeb® X-19S is a high-density multi-purpose I/O expansion module designed to add substantial control and monitoring capacity to an X-400™ or X-600M™ system. Combining 16 relays, 16 optically isolated digital inputs, and 4 analog inputs in a single compact unit, the X-19S is an excellent fit for applications that demand a large number of I/O points without requiring multiple separate modules.
Built with industrial-grade screw terminal connections and powered through the expansion bus, the X-19S supports scalable system growth while keeping installation clean and efficient. It is ideal for building automation, process control, OEM equipment, security systems, freezer door monitoring, pulsed flow meters, solenoid valves, lighting control, and other applications where a high I/O count is needed in a compact footprint.
Key Features
- 16 Relays: Provides high-density relay control for a wide range of moderate-load switching applications.
- 16 Digital Inputs: Enables extensive monitoring with optically isolated input channels.
- 4 Analog Inputs: Adds analog measurement capability in the same module.
- Expansion Module for X-400 and X-600M: Designed to integrate seamlessly with ControlByWeb expansion systems.
- Scalable I/O Capacity: Multiple X-19S modules and other expansion modules can be connected as needed.
- Industrial Screw-Terminal Connections: Provides secure and reliable wiring for all I/O points.
- LED Status Indication: 33 LEDs provide clear visual feedback for relays, inputs, and power.
- Powered Through Expansion Bus: No separate power supply is required for the module itself.
