WEEKLY TIME SWITCH 1IO 7081 PERRY – 2 DIN Digital Weekly Electronic Timer

The WEEKLY TIME SWITCH 1IO 7081 PERRY (model 1IO 7081 manufactured by Perry Electric) is a professional 2-DIN rail digital time switch designed for precise automated control of civil, commercial, and industrial electrical circuits. Powered by 230V AC mains, the WEEKLY TIME SWITCH 1IO 7081 PERRY operates a 1-channel volt-free potential-free changeover relay rated at 16 A (250V AC).

As highlighted in the product image, this unit features a 2-module DIN housing (RAL 7035 grey thermoplastic), a high-visibility 1.33-inch backlit LCD screen, simplified front control keys, and transparent protective flip-cover shielding. It offers flexible 24-hour and 7-day program scheduling (matchable in blocks of days) with down to 1-second minimum switching intervals.

Key Features of the WEEKLY TIME SWITCH 1IO 7081 PERRY

• Flexible 7-Day & 24-Hour Scheduling: Allows setting up to 20 to 58 ON/OFF program cycles (depending on revision series) that can be individually assigned or grouped across blocks of days.

• 1-Second Minimum Switching: Supports short-duration pulse triggering down to 1second, ideal for bells, signaling systems, and timed pumps.

• Automatic Daylight Saving Time (DST): Automatically adjusts system time forward and backward for summer/winter daylight saving changes across 4 geographic zones.

• 1.33″ Backlit LCD Display: Displays active channel state, real-time hour/minute clock, current date, and active programming blocks even in dim panel boards.

• Power Backup Reserve: Keeps accurate time during mains power blackouts using internal battery backup reserve (up to 15 days or lithium cell reserve options depending on production batch).

• Manual Override & Reset: Provides immediate advance ON/OFF manual switching buttons on the front interface without altering stored automated program schedules.

Common Applications and Industrial Usage

The timing precision, heavy contact load rating, and DIN rail footprint of the WEEKLY TIME SWITCH 1IO 7081 PERRY make it suitable for multiple automated energy management uses:

• Commercial & Architectural Lighting: Controls scheduled switching for shop display windows, streetlights, outdoor signages, and floodlights.

• HVAC & Climate Control Systems: Schedules heating pumps, ventilation fans, air handling units, and water circulation pumps in offices and apartment complexes.

• Irrigation & Water Pumping: Automates scheduled garden/agricultural watering cycles and pool filtration systems.

Installation Guidelines and Best Practices

CRITICAL SAFETY NOTICE: Electrical installation must be performed by a qualified electrician. Always isolate the main AC power supply before wiring the switchboard.

• Power Terminals: Connect the incoming 230V AC Line (L) and Neutral (N) power feed wires into the dedicated power supply screw terminals on the base.

• Load Contact Connections: Wire the controlled load circuit across the potential-free changeover relay terminals (NO/NC/Common) according to the panel wiring diagram.

• Initial Resetting: Upon first installation, insert a pointed tool into the front RESET pinhole to clear internal memory and initialize system parameters.
