The ABB 2CSM222531R1000 is a versatile digital time switch engineered for automated electrical circuit control—compatible with ABB low-voltage distribution systems (e.g., S800 series distribution boards) and widely used in industrial, commercial, and residential applications. It functions as a programmable timing device to automatically switch connected loads (e.g., lighting, motors, heating systems) on/off based on pre-set schedules, reducing energy waste and improving operational efficiency. Designed for user-friendly programming, high timing accuracy, and robust environmental performance, it operates reliably in diverse environments (e.g., factories, offices, shopping malls, residential buildings) where precise time-based control is critical. Below is its detailed specification:
- Product Model: 2CSM222531R1000
- Order Code: 2CSM222531R1000
- Product Series: ABB Digital Time Switch Series (7-day programmable, LCD display)
- Core Function: Controls electrical loads via pre-programmed time schedules; supports daily/weekly cycles, holidays, and manual override; provides real-time clock with battery backup; ensures accurate time-based switching for energy management
- Electrical Specifications:
- Mechanical Specifications:
- Housing Material: Flame-retardant polycarbonate (UL94 V-0); IP40 front panel protection
- Dimensions (W×H×D): 72mm × 72mm × 55mm (standard DIN 43880 panel cutout)
- Mounting: Panel-mounted (cutout size: 67mm × 67mm); secured with 4 M3 screws (torque: 0.8 N·m)
- Weight: Approximately 180g
- User Interface: 128×64 pixel LCD display (backlit); 4 navigation buttons; 1 manual override switch
- LED Indicator: Green (output active); Red (program error/backup low)
- Environmental Ratings:
- Operating Temperature Range: -5℃~+55℃ (23℉~131℉)
- Storage Temperature Range: -20℃~+70℃ (-4℉~158℉)
- Humidity Tolerance: ≤95% RH (non-condensing, 40℃; suitable for damp environments)
- Vibration Resistance: 10~500Hz, 1g acceleration (IEC 60068-2-6; no program loss)
- Shock Resistance: 15g acceleration (11ms duration, IEC 60068-2-27; maintains clock accuracy)
- Compliance Standards: IEC 61038 (time switches), EN 61000-6-2 (EMC immunity), UL 60730-1 (household electrical appliances), CE, RoHS
- Flexible Programming: Supports 50 on/off events, 8 weekly programs, and 10 holiday settings—accommodates complex schedules (e.g., different weekday/weekend lighting times in offices, seasonal adjustments for heating systems).
- Astronomical Clock Function: Automatically adjusts switching times based on sunrise/sunset (configurable by latitude/longitude)—ideal for outdoor lighting (e.g., parking lot lights, building facades) to optimize energy use.
- High Timing Accuracy: ±1 minute/month drift ensures reliable schedule execution, avoiding premature/delayed switching (critical for time-sensitive applications like factory production line pre-heating).
- Battery Backup: 3-year CR2032 battery maintains clock and programs during power outages—eliminates re-programming after grid failures, ensuring uninterrupted operation.
- User-Friendly Interface: Backlit LCD display and intuitive 4-button navigation simplify programming (no specialized training required); supports multiple languages (English, German, French, Spanish, etc.).
- Manual Override: Dedicated switch allows temporary bypass of programmed schedules—convenient for maintenance (e.g., keeping lights on during evening repairs) without altering stored programs.
- Wide Load Compatibility: 16A resistive/8A inductive capacity directly controls medium-power loads (e.g., 4kW lighting, 2.5kW pumps) without external contactors—reduces system complexity and cost.
- Commercial & Industrial Lighting Control: Primary application—automated lighting management:
- Office Buildings: Controls fluorescent/LED lighting systems; programs "working hours" (8:00~18:00) for weekdays and "reduced hours" (9:00~12:00) for weekends, cutting energy consumption by 30% compared to manual switching.
- Parking Lots & Warehouses: Uses astronomical clock to activate outdoor lighting 30 minutes before sunset and deactivate 30 minutes after sunrise; 8A inductive capacity handles LED floodlights with drivers.
- HVAC & Energy Management: Optimizes heating/cooling operation:
- Shopping Malls: Regulates air conditioning systems—starts 1 hour before opening (9:00) and stops 1 hour after closing (22:00); holiday settings disable operation on public holidays, reducing energy waste.
- Factory Production Lines: Pre-heats industrial ovens 30 minutes before shift start (7:30) and shuts down heating after shift end (17:30); precise timing ensures equipment readiness while minimizing idle energy use.
- Residential & Infrastructure Auxiliaries: Automates household and public services:
- Residential Complexes: Controls communal area lighting (corridors, stairwells) with "night mode" (22:00~6:00) at reduced brightness; manual override allows residents to extend lighting as needed.
- Water Supply Systems: Activates booster pumps for 2-hour intervals (6:00~8:00, 18:00~20:00) during peak water usage, avoiding continuous operation and reducing pump wear.
- Agricultural & Horticultural Systems: Manages cultivation environments:
- Greenhouses: Controls irrigation pumps and grow lights—12-hour light cycles (6:00~18:00) for plant growth, with adjustable schedules for different crop stages; ensures consistent growing conditions.
