Real-Time Clock
-
The internal RTC allows for scheduled operations, such as timed lighting, pump control, or heating systems.
-
-
User-Friendly Programming
-
Use Zelio Soft 2 for intuitive programming with ladder diagrams or function block diagrams. Also programmable from the front panel for quick changes.
-
-
AC Powered (100–240V)
-
Operates directly from standard AC supply—no need for external power converters.
-
-
Expandable & Modular
-
Can be expanded with additional I/O modules if your application grows, ensuring long-term flexibility.
-
-
Reliable Relay Outputs
-
Relay contacts ensure safe switching of both resistive and inductive AC loads, offering reliable performance in automation scenarios.
-

Lighting Automation (e.g. store displays, timed exterior lights)
-
Irrigation Systems (e.g. garden or agricultural automation)
-
Access Control (e.g. timed gate or door opening)
-
HVAC Scheduling (fan, heater, or AC control by time)
-
Small Machine Control (e.g. conveyors, feeders, mixers)
-
Energy Management (e.g. time-based device shutdown/startup)
