Description
The ControlByWeb® X-12S is an eight relay expansion module designed to add reliable switching capability to an X-400™ or X-600M™ controller. Featuring 8 independent Form A (SPST) relays, the X-12S is ideal for industrial and OEM applications that require flexible, low-current relay expansion without adding complexity. Each set of four relays shares common wiring, helping simplify installation while still supporting practical control for moderate loads.
Built for scalable system expansion, the X-12S connects directly through the expansion bus, which supplies both power and communication from the host controller. Its removable terminal connector makes wiring straightforward, and the integrated relay LEDs provide quick status visibility at a glance. Whether used for irrigation, alarm panels, low-power lighting, or dry contact closures, the X-12S offers a dependable and efficient way to expand relay control in a networked automation system.
Key Features
- 8 Relay Outputs: Adds eight independently controlled Form A (SPST) relays to an X-400 or X-600M controller.
- Expansion Module Design: Provides scalable relay expansion without requiring a separate power supply.
- Simple Wiring: Relay commons are grouped in two banks for easier installation.
- Removable Connector: Streamlines wiring and maintenance.
- Relay Status LEDs: Eight relay indicators make it easy to see output activity at a glance.
- Powered Through Expansion Bus: Receives power and communication directly from the host controller.
- Reliable Low-Current Switching: Ideal for moderate-load applications such as alarm panels and lighting control.
- Expandable System Option: Multiple X-12S modules can be added for larger control systems.
