Honeywell 900A16-0103 ControlEdge 900 High Level Analog Input Module

Configured for high-density analog voltage signal acquisition in ControlEdge 900 platform architectures, the Honeywell 900A16-0103 (900A16 High Level Analog Input Module) provides direct physical/electrical execution of 16-channel high-level sensor inputs.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

The 900A16-0103 module acquires +/- 10 VDC high-level voltage inputs across 16 isolated channels with a 100 ms scan execution time. Built to integrate within process control racks processing 4-20 mA HART loop protocol instruments, the module input circuitry enforces strict channel-to-channel isolation. This limits current leakage to 2 uA max per channel, preventing signal attenuation and electrical ground loops across differential measurement points.

Frequently Asked Questions

Q: What are the backplane power supply current requirements for the 900A16-0103 module?

A: The module draws a maximum backplane load of 75 mA at 5 VDC and 50 mA at 24 VDC.

Q: What is the maximum channel scan rate for the 16 analog input signals?

A: All 16 channels are processed continuously with an update interval of 100 ms.

Field Installation Guidelines

1. Power down the controller rack backplane before inserting or removing the module from its slot.
2. Route high-level voltage signal wiring using twisted-pair shielded cable, grounding the cable shield at a single termination point on the rack chassis.
3. Keep field input conductors separated from high-voltage AC cables in wire ducts to prevent capacitive crosstalk.
4. Verify all field wiring terminals are fully seated and tightened to prevent loose high-resistance analog sensor connections.
