Key Parameters 1. Power Supply: Supply Voltage: 24V DC (typical range 19.2 - 28.8V DC). Power Consumption: Approx. 6W. 2. Inputs (I): Number & Type: 12 digital inputs. Input Logic: All 12 inputs can be configured via software. They are suitable for standard DC switching signals (e.g., from pushbuttons, sensors). Special Function: Several inputs can be configured as high-speed counters (up to 1 kHz) or for frequency measurement. 3. Outputs (Q): Number & Type: 8 relay outputs. Contact Rating: 5 A at 250V AC / 5 A at 30V DC (resistive load). Specific ratings apply for inductive or lamp loads—refer to the datasheet for de-rating. Electrical Life: Typically > 100,000 operations at rated load. 4. Core Feature: Integrated Timer/Clock (TC): Real-Time Clock: Built-in battery-backed real-time clock (year, month, day, hour, minute, second). Function: Enables powerful time-switching functions directly in the program (e.g., "ON from 08:00 to 17:00 on weekdays," seasonal schedules, astronomical clock for dusk/dawn simulation). Battery Backup: Internal capacitor (or optionally a battery) maintains the clock during brief power interruptions. 5. Programming & Display: Programming Methods: EASY-SOFT PC Software: Intuitive, graphical programming using function blocks (logic gates, timers, counters, etc.). On-Device Programming: Using the rotary switch, push buttons, and integrated LCD display. Display: 2-line, 16-character backlit LCD. Shows I/O status, current time, values, and user-defined text messages. Memory Capacity: Sufficient for several hundred network elements (function blocks). 6. Special Functions (via Programming): Timers: On-delay, off-delay, pulse, cyclic, etc. Counters: Up/Down. Analog Value Processing: Comparators and thresholds for use with analog expansion modules. Logic Operations: AND, OR, NOT, XOR, etc. Text Messages: Can display custom messages on the LCD. 7. Expansion Capability: Expansion Modules: Can be expanded by connecting up to 2 EASY expansion modules (e.g., EASY-IO for additional digital I/O, or EASY-400-ANALOG for analog inputs). Note: The 512 series (EASY500) is generally not expandable with bus communication modules, unlike the higher-end 7xx or 8xx series. 8. Mechanical & Environmental: Mounting: Standard 35 mm DIN rail. Dimensions (WxHxD): Approx. 90 x 110 x 58 mm. Protection Class: IP20 (for enclosure mounting). Operating Temperature: -25°C to +55°C. 9. Certifications: cULus Listed, CE, GL (Germanischer Lloyd), DNV, RoHS compliant. 10. Typical Applications: Time-controlled lighting systems (building corridors, facades, parking lots). HVAC control (pumps, fans, heating circuits based on schedules). Simple machine automation (conveyors, packaging machines). Pump control and irrigation systems. Ventilation and shutter control.
