6-7. CONTROL I/O CHARACTERISTICS
• GPI inputs ch1-12: optically isolated. Load current = 3 mA (typical). See figure 1.
• GPI inputs ch13-16: optically isolated. IN+ input voltage range = 5 V to 24 V, Load current = 2 mA @5 V or 10 mA@24 V (typical). See
figure 2.
• GPI outputs ch1-10: Open collector outputs. Maximum current draw 75 mA (per channel). Withstand a voltage of 12 V. See figure 3.
• GPI +5 V outputs: Output voltage = 5 V ±0.25 V, Maximum supply current in total = 300 mA. See “6-10. Pin assignment / GPI [OUTPUT]
connector.”
