Product Features
Four Configurable Input or Output Channels
The G-ULTRA provides four 50mA channels that can be independently configured as either inputs or outputs. This flexibility enables integration into diverse applications ranging from alarm monitoring to device control.
Two Onboard Relays for High-Power Switching
Includes two 1A onboard relays for controlling heavier loads such as automated gates, irrigation pumps, or lighting circuits. Output modes can be configured as pulsed or latched for precise control.
Advanced Access Management
Supports up to 1,500 access numbers and 20 access profiles, allowing you to control who can trigger outputs and when. Ideal for large residential estates, commercial premises, or mobile fleets requiring multiple authorized users.
Extensive Event Logging
Tracks up to 5,000 events, providing a detailed record of device activity, user access, and system triggers for auditing or troubleshooting purposes.
