LD Systems SGP 42 Ethernet I/O Interface with GPIO & Relays

LD Systems SGP 42 Ethernet I/O Interface with GPIO & Relays

The LD Systems SGP 42 Ethernet I/O Interface is a compact network-enabled control module for professional automation systems. It provides configurable GPIO, relay outputs, RS232 connectivity, Ethernet networking, PoE support, and QUESTRA platform integration for controlling buttons, sensors, indicators, serial devices, and automated AV functions.

This Ethernet I/O expansion interface is built for integrators who need compact AV automation control, network GPIO relay control, or a QUESTRA-compatible control interface for installed systems. It supports dry contact triggers for buttons and presence sensors, TTL-level GPIO output signals, and normally open relay outputs for dependable system control.

The SGP 42 fits professional environments where media control, lighting, building functions, and third-party hardware need to work together through centralized configuration. Its metal powder-coated enclosure, status LEDs, PoE support, optional external power input, and included surface mount accessories make it practical for technical enclosures, wall mounting, and surface installations.
