Module Features & Design

• High channel density (32 inputs) maximizes space efficiency in control cabinets.
• Wide input range (10-32V DC) supports standard 12V and 24V DC industrial control circuits.
• Two isolated groups (16 channels each) allow connection to two separate DC power sources.
• Fast 5ms response time ensures quick detection of state changes for process interlocks.
• Individual per-channel LEDs provide instant visual status feedback for troubleshooting.
• Extended operating temperature range (-40°C to +70°C) ensures reliability in harsh environments.
• Designed as a sinking input; the field DC voltage is applied between the input terminal and the common terminal.

Installation & Wiring Guidelines

• Install in a compatible Honeywell HC900 rack. A Euro style 36-terminal block is required for field connections.
• Connect the DC common (negative) of the field supply to the appropriate COM terminal pair for the channel group.
• Connect the switched DC positive wire from field devices (e.g., sensors, contacts) to the desired input terminals.
• Wire channels 1-16 to one common pair and channels 17-32 to the other to maintain isolation between groups.
• Ensure the field power supply is within the 10-32V DC range and can provide the required input current.
• Use proper wire gauges and follow local electrical codes for low-voltage DC wiring.

Typical Applications

• Monitoring proximity switch, photoelectric sensor, and limit switch status.
• Reading relay and solid-state switch outputs.
• Process interlock and safety system status monitoring.
• General-purpose DC status input for machine control and automation.
