• Each analog channel converts in 1 ms plus one controller cycle time.
• Input state 1 guarantees at least 15 V and 2.5 mA for dependable triggering.
• Input state 0 stays below 5 V and 1 mA to reject noise.
• Fast inputs respond in 5 µs, while standard inputs respond in 35 to 100 µs.
• Configurable input filtering of 0, 3, or 12 ms suppresses contact bounce.

Environmental Resistance and Immunity

• Electrostatic discharge withstands 4 kV contact and 8 kV air per EN/IEC 61000-4-2.
• Radiated field immunity reaches 10 V/m from 80 MHz to 1 GHz.
• Fast transient immunity covers 2 kV on power lines and 1 kV on I/O.
• Surge withstand handles 1 kV common mode on shielded cable and I/O.

• Vibration resistance meets 3 gn at 8.4...150 Hz on panel or rail.
• Shock resistance meets 15 gn for 11 ms test waves.
• Emission complies with EN/IEC 55011 class A for industrial environments.

Installation Guide

• Mount the controller on a TH35-7.5 or TH35-15 rail per IEC 60715, or fix it to a panel.
• Wire 24 V DC power to the 3-terminal block and observe the 19.2...28.8 V limit.
• Keep fast output cables shielded and shorter than 3 m for clean signals.
• Limit standard output cable to 30 m unshielded and input cable to 30 m unshielded.
