Key Technical Data Explained
Measurement range: Not applicable for this logic controller. It handles digital signals, not analog measurement.
Frequency response: Fast inputs support 10 kHz high-speed counting. Pulse outputs reach 100 kHz for PTO/PWM tasks.
Sensitivity: Digital inputs respond to standard 24 VDC logic levels. Fast inputs suit encoder and pulse signals.
Linearity: Not applicable. This unit uses digital I/O, not analog conversion.
Resolution: Counter and pulse functions work at 10 kHz input and 100 kHz output rates.
Temperature range: Runs from 0 to +55 °C. Stores from -25 to +70 °C.
Environmental tolerance: Handles 10…95% relative humidity, non-condensing. Rated IP20 for cabinet use.
Interference immunity: Built for industrial cabinets. Use proper grounding, shielded cables, and stable 24 VDC supply.
Installation Guide
- Mount the controller on a 35 mm DIN rail inside a protected cabinet.
- Keep clear space above and below for airflow.
- Use a stable 24 VDC supply within 19.2…28.8 V.
- Wire digital inputs and outputs with correct polarity.
- Use shielded cable for RS-485 and fast pulse signals.
- Ground the panel and follow local electrical codes.
- Do not exceed 0.5 A per transistor output point.
Commissioning and Maintenance
- Program with SoMachine or EcoStruxure Machine Expert.
- Connect through mini USB-B for fast setup.
- Use Modbus RTU/ASCII over RS-485 for field devices.
- Add a TMCOM cartridge for Modbus, CANopen, or Profibus expansion.
