Module Features & Protection

• Low-side sinking outputs are ideal for interfacing with PLCs and devices that expect a common positive voltage.
• Intelligent Power Switch (IPS) technology provides efficient switching with low voltage drop.
• Electronic overload protection guards against short circuits and overtemperature conditions.
• Clear multi-color module status LEDs indicate operational mode: normal scan, forced outputs, or faults.
• Protection reset requires cycling the external field power, preventing automatic restart after a fault.
• No external fuses required; protection is integrated electronically.
• Grouped isolation (2 groups of 8) allows connection to two different DC power sources.

Installation & Wiring Guidelines

• Install in a compatible Honeywell HC900 rack. Provide external DC power (6.5-32V) for the field loads.
• Connect the external DC+ supply to the common positive of the field loads.
• Connect the load between the output terminal (sinking side) and the DC- (common negative).
• Wire outputs in groups of 8, each group to its own +V and COM terminals on the module.
• Do not exceed 1A continuous current per output or 8A total per module.
• For inductive loads, use external flyback diodes across the load to protect the output switch.
• If an overload trips, disconnect the field power to reset the module's protection circuit.

Typical Applications

• Driving indicator lamps, LED arrays, and small DC relays.
• Controlling solenoid valves and low-power DC actuators.
• Interfacing with other control systems requiring a sinking input signal.
• General-purpose DC output control in machinery and automated systems.
