The 900H02-0102 module from Honeywell is a DC digital output card for process control systems. Specifically, it provides sixteen outputs split into two groups of eight channels. Each group receives external power through a dedicated pair of screw terminals for +V and COM. This layout lets engineers isolate field wiring into separate power domains. Furthermore, the outputs use low side switching, also known as current sinking. As a result, the module suits loads that share a common positive supply.
Each output relies on an intelligent power switch (IPS) design. The operating voltage range spans 6.5 to 32 VDC, with a reduced range of 5.0 to 6.5 V at loads below 0.5 A per channel. Additionally, the peak voltage rating reaches 34 VDC. The ON voltage drop measures only 0.3 VDC at a 1 A load, which keeps heat generation low. Overload protection uses electronic high current and high temperature limiting. When a trip occurs, the user must recycle field power to reset the module.
The maximum load current is 1 A per point and 8 A per module for resistive loads. For incandescent lamp loads, the limit drops to 0.5 A per point with a maximum inductance of 5 mH. Moreover, the maximum inrush current reaches 4 A for 10 ms, and leakage current stays below 0.15 mA at 32 VDC. The minimum load is 0.0 mA. Both the OFF-to-ON and ON-to-OFF response times are 6 ms. Fuses are electronic limiting type, so no physical fuse replacement is needed.
A green LED sits beside each channel and lights when the output is ON. Meanwhile, a green blinking status LED shows that the module is being scanned. An amber blinking status LED indicates forced channels, and a red status LED signals module diagnostics. These visual cues help technicians troubleshoot wiring faults quickly. Besides, galvanic isolation separates the two output groups, which reduces cross-talk between field circuits.
The module draws 340 mA at 5 V from the backplane and 0 mA at 24 V. Installers should confirm that the chassis power budget covers this load. The card operates within the standard HC900 cabinet environment, so keep the surrounding air free of corrosive gases and heavy dust.
First, confirm that the slot supports the 900H02-0102 module and that the backplane has spare 5 V capacity. Next, wire the external +V and COM terminals for each group before inserting field leads. Then, seat the module firmly and tighten the retaining screw. Afterward, verify channel LEDs during a scan cycle. Finally, test each output with a known load to confirm switching behavior.

Q1: How many outputs does the Honeywell 900H02-0102 provide?
A: It offers 16 outputs in two groups of eight channels. Each group has its own +V and COM terminals.
Q2: What does "current sinking" mean for this module?
A: The outputs switch the low side of the load to ground. Therefore, field devices share a common positive supply.
Q3: How do I reset the module after an overload trip?
A: You must cycle the field power. The electronic protection latches until power is removed and reapplied.
Q4: What is the maximum current per channel?
A: The limit is 1 A per point for resistive loads. For incandescent lamps, keep it at 0.5 A per point.
Q5: How fast can you ship this item?
A: We ship via Fedex, UPS, and DHL. Delivery typically takes 3 to 7 business days, depending on your location.
