Get smart with the fully programmable IDEC SmartRelay, a compact, expandable CPU that can replace multiple timers, relays and counters. Each CPU houses a real-time clock and calendar, and supports optional expansion I/O modules to enhance your control and monitoring applications. Program and edit using either the "smart" on-board selection buttons and display interface, or our even "smarter" software, WindLGC. The IDEC SmartRelay is the ideal solution for managing automatic lighting, access control, watering systems, pump control, or ventilation systems in factory or home automation.
