Non-Isolated I/O (or BCD Interface):

IN9 - IN 16: These inputs may be used with open collector outputs without an external supply by connecting the output device common (ground) to signal ground on the unit, and the open collector to the input pin. An internal pullup resistor to +5V DC is provided.

• Logic High Input Level: 25V > Vsource > 4.5V, or open circuit
