Module Features & Design

• True universal input accepts both AC (80-264V) and DC (80-125V) signals on the same terminals.
• Each of the 16 channels is individually isolated from each other and from chassis ground (350V AC max).
• High input impedance (48kΩ) minimizes loading on the sensed circuit.
• Wide voltage ranges accommodate global power standards and various industrial control voltages.
• Individual per-channel LEDs provide immediate visual confirmation of the input state.
• Requires an external Euro style 36-terminal block for field wiring connections.
• Ideal for mixed signal environments or applications where sensor voltage type may change.

Installation & Wiring Guidelines

• Install in a compatible Honeywell HC900 rack. The module is externally powered by the field voltage.
• Use the specified Euro style 36-terminal block (not included) for all field connections.
• Each input requires two terminals: connect the field voltage across them (polarity sensitive for DC).
• Ensure the applied voltage (AC or DC) is within the specified ranges for reliable operation.
• For AC signals, frequency must be between 47-63 Hz.
• Follow all local electrical codes for the voltage level being used. Use appropriate wire gauges.
• Individual channel isolation allows mixing of different voltage sources on the same module.
