12 DO 12 UI

Improvements in Revision 2.0

• Reduced power consumption of relay outputs when ON
• Double-row connector for UI inputs – 2 holes per each UI input
  

Features

• 12x potential-free relay outputs, 10 A
  • Relay lifetime: 100,000 cycles at max load, 2,000,000 cycles at average load
  • Maximum total load 20 A
  • Sensors near relays monitor their temperature and shut them down if it exceeds safe levels. Error is shown in the app.
• Output configurations:
  • Independent switched output
  • AC blinds with internal blocking of both outputs
  • PWM output
• 12 universal inputs configurable for:
  • NTC temperature inputs with resistance range 100 Ohm – 100 kOhm ±50 Ohm. Deviation over 1 km Cat6 cable: -0.3 °C at 25 °C. AREF terminal ensures noise-free temperature measurement.
  • Button inputs
  • Reed / status inputs
  • Pulse counter inputs, 200 Hz per channel, 400 Hz sampling rate per channel, pulse width > 2.5 ms
  • Analog inputs 0–10 V, voltage range 0–26 VDC, single-ended, 12-bit resolution, 0.1% full-scale accuracy, input impedance > kOhm, 50 dB common-mode rejection at 60 Hz, conversion time 1250 ms
  • For 4–20 mA analog input, connect 500 Ohm resistor and set minimum voltage to 2V in Service settings (see gallery screenshot)
• Standby power consumption: 1 W
• Power consumption per active relay: 0.8 W
• Power dissipation per 1 A load: 0.16 W
• Maximum power dissipation at full 20 A load with all relays active: 1 + 0.8 x 12 + 0.16 x 20 = 13.8 W
• Power supply 24 VDC ±10 %
• Enclosure: IP20, operating temperature: -20 °C to 40 °C
• DIN rail, 6 modules. Width 107 mm, height 59 mm.
