Honeywell 900H01-0102 Relay Output Module, 8 Ch

Product Overview

The Honeywell 900H01-0102 is a Digital Output Module providing 8 channels of 24 VDC transistor output for the Honeywell ControlEdge HC900 system. Featuring sourcing (PNP) outputs, this module drives 24 VDC loads such as solenoid valves, relay coils, and indicator lamps with fast switching response and electronic short-circuit protection. Transistor outputs offer longer life and faster switching than relay outputs for DC-only applications.

Key Features

• 8 Transistor Output Channels: 24 VDC sourcing (PNP) outputs
• Fast Switching: Faster response than relay outputs for high-speed applications
• Electronic Protection: Short-circuit and overload protection per channel
• Status LEDs: Per-channel output state indication
• Hot-Swap Capable: Replace without system shutdown
• Compact Design: Standard HC900 module form factor

FAQ

Q: What is the difference between 900H01-0102 and 900H01-0202?
A> 900H01-0202 is a later revision. Both are 8-channel 24 VDC transistor output modules.

Q: Can transistor outputs switch AC loads?
A> No. Transistor outputs are DC-only. For AC loads, use 900H02 relay output modules.

Q: What happens during a short circuit?
A> The affected channel enters current-limiting mode. The fault is reported to the controller, and the channel automatically resets when the short is removed.

Selection Tips

• Use 900H01-0102 for DC-only applications requiring fast switching
• Calculate total load current to ensure 24 VDC supply capacity
• For AC loads or galvanic isolation, use 900H02 relay outputs instead
• Install external flyback diodes for all inductive DC loads
