900H02-0202 Honeywell Digital Output Module | 16-Channel 24VDC

Engineering Precision: Honeywell 900H02-0202

The 900H02-0202 is a robust 16-channel digital output module engineered for the Honeywell Experion control platform. Designed for industrial reliability, this unit features low-side switching (current sinking) architecture. The module organizes its 16 outputs into two isolated 8-channel banks, providing flexible power distribution for critical field devices.

Core Technical Parameters

• Model: 900H02-0202
• Channel Density: 16 outputs (2 groups of 8 channels).
• Switching Type: Low-side (current sinking) Intelligent Power Switch (IPS).
• Operating Range: 6.5VDC to 32VDC.
• Load Capacity: 1A per point (8A max per module, resistive).
• Response Time: 6ms (OFF to ON / ON to OFF).
• Inrush Handling: 4A for 10ms (incandescent lamp compatible).
• Voltage Drop: 0.3VDC at 1A load.
• Protection: Integrated electronic high-current/temperature limiting.

Advanced Diagnostics & Status Monitoring

The 900H02-0202 enables rapid troubleshooting through an intuitive LED diagnostic array:

• Channel Status: Green LED for active digital output state.
• Scan Status: Green blinking LED confirms active CPU communication.
• Forced Status: Amber blinking LED signals active channel overriding.
• Fault Detection: Red LED alerts operators to internal module diagnostics or trigger events.

Professional FAQ

What is the procedure if the module's overload protection trips?
Once an electronic limit is tripped, the module enters a safety state. You must physically cycle the external field power to reset the intelligent power switch.

Can I use this module to drive incandescent lamps directly?
Yes, the 900H02-0202 handles up to 0.5A per point for incandescent loads, provided the total module load does not exceed 8A.

How do I distinguish between an active output and a forced signal?
A steady green LED indicates normal output activity, whereas a blinking amber LED provides visual confirmation that the channel is currently forced via your control software.

Selection Guide: What should I consider regarding leakage current?
With a maximum leakage of 0.15mA at 32VDC, this module is highly efficient. Ensure your downstream actuators do not "float" or activate due to this minor current when the output is in the OFF state.

Why is point-to-point isolation important for this output type?
The module's split-group isolation allows you to segment your output devices into two distinct power zones, preventing a short circuit in one group from affecting outputs in the other.
