Electrical and integration notes
Requires an external 24 V DC supply (20.4...28.8 V). Draws 40 mA at 24 V DC external plus 50 mA at 5 V DC from the backplane. Each channel samples every 10 ms plus one controller cycle time. Input impedance: 10 Ω for current mode, ≥1 MΩ for voltage. Dielectric strength 500 V between I/O and logic circuits; photocoupler isolation. Wiring via a single removable screw terminal block. Use shielded cable for best noise immunity. Overload rating: 13 V for voltage inputs, 40 mA for current inputs.
