Product details

Product Brief

900H02-0202 is a 16-channel digital output module from Honeywell.
It provides low-side switching (current sinking) for industrial loads.
Each module has 2 isolated groups of 8 outputs with external power.
Built-in overload protection resets after cycling field power.
LED indicators show channel status, scanning, forcing, and diagnostics.

Key Features

16 current-sinking outputs – low-side switching for robust control.
2 galvanically isolated groups – 8 channels per group for noise immunity.
Intelligent power switch (IPS) – handles inrush up to 4 A for 10 ms.
Electronic high-current & temp limiting – auto resets after power cycle.
Fast response – 6 ms OFF↔ON for time-critical applications.
Diagnostic LEDs – green for ON, blinking green for scan, amber for forced, red for faults.

Technical Specifications

Brand: Honeywell
Model: 900H02-0202
Outputs per module: 16 (current sinking, low side)

Peak voltage: 34 VDC
ON voltage drop: 0.3 VDC @ 1 A load
Overload protection: electronic current/temp limiting, resets after field power cycle
Max load current: 1 A per point, 8 A per module (resistive); 0.5 A per point (incandescent, 5 mH max)
Max leakage current: 0.15 mA @ 32 VDC
Max inrush: 4 A for 10 ms
Min load: 0.0 mA
OFF↔ON response time: 6 ms
ON↔OFF response time: 6 ms
Fuses: electronic limiting
Power supply loading: 5 V; 340 mA / 24 V; 0 mA
Frequency response: DC only (N/A for AC)

Temperature range: -40 °C to +70 °C (ambient)
Environmental tolerance: 5–95 % RH non-condensing, vibration 5 g @ 10–500 Hz
Noise immunity: > 1 kV ESD (IEC 61000-4-2), fast transients (IEC 61000-4-4)

Installation & Commissioning

Mounting: DIN-rail or panel mount (use supplied clips).
Wiring: 2 groups of screw terminals (+V and COM per group).
Group isolation: each group requires separate external power supply.
Reset after overload: cycle field power – no manual fuse replacement.
LED quick check: green steady = ON; green blink = scan; amber blink = forced; red = diagnostics.

Maintenance & Service

Diagnostics: red LED indicates fault; check group power and load.
Field power cycling: resets electronic protection without disassembly.
Module status: blinking green confirms PLC scanning – easy troubleshooting.
No calibration needed – digital outputs are fixed logic levels.
Cleaning: use dry cloth; avoid solvents.

Compatibility & Certifications

Compatible with: Honeywell ControlEdge, Experion, and most PLC/DCS systems (24 VDC sink inputs).
Certifications: CE, UL 61010-1, CSA, RoHS, ATEX (Zone 2).
Galvanic isolation: 1500 VAC between groups and backplane.

Expert Review – Manager’s Insight

“This module offers reliable low-side switching with true galvanic isolation. The electronic protection eliminates fuse replacement, reducing downtime. Its wide voltage range (6.5–32 VDC) suits varied field supplies. For high-density digital output applications, this is a solid, cost-effective choice.”

Application Scenarios

Suitable for: PLC/DCS output cards, valve actuators, motor contactors, indicator lamps, solenoid drivers.
Ideal in: process automation, packaging lines, material handling, HVAC, and machine tools.
Works with: resistive and incandescent loads (up to 0.5 A per channel).

Frequently Asked Questions (FAQ)

Q: What does the red LED indicate?
A: Red LED shows a module diagnostic – check group power and load for short/open.
Q: How do I reset an overloaded channel?
A: Cycle the field power (turn off +V and COM) – electronic protection resets automatically.
Q: Can I mix loads on the same group?
A: Yes, but total current per group must not exceed 8 A (resistive) or 4 A (incandescent).
Q: Is this module compatible with 5 V logic?
A: Yes, it operates from 5 V (with <0.5 A/ch) up to 32 VDC.
Q: What happens if I exceed the max inrush?
A: The IPS limits current; repeated overcurrent may trip protection – cycle power to reset.
Q: Can I use this module with AC loads?
A: No – it is for DC loads only (6.5–32 VDC).
Q: How many modules can I install per rack?
A: Depends on backplane power; each module draws 340 mA at 5V.

Selection Guide – Tips from Experience

Choose this module when you need 16 isolated outputs with group power flexibility.
For incandescent lamps, limit to 0.5 A per channel and check inrush (4 A for 10 ms).
Use separate power supplies for each group to maximize isolation and noise rejection.
If you need more than 8 A per group, consider two modules or higher-current alternatives.
Always wire COM terminals correctly – low-side switching sinks current to ground.
