More Information

Overview Manuals Inputs Cycle Faults Terminal

Features:

  • Sixteen isolated channels can be configured individually for voltage or current input.
  • Analog-to-digital conversion is synchronized with CPU execution on a 100 ms module cycle.
  • Calibration, channel configuration, and diagnostic state are managed at the module level.
Honeywell 900A16-0103 brings sixteen high-level analog field signals into a ControlEdge 900 controller through one isolated input module.

Each channel accepts its configured voltage or current range, while point-to-point isolation prevents the field inputs from sharing a direct electrical path.

The module stores calibration and configuration data in non-volatile memory and reports scanning or diagnostic conditions through separate green and red status LEDs.

The Honeywell 900A16-0103 16-Channel High-Level Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell 900A16-0103 16-Channel High-Level Analog Input Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

How field signals are organized

  • Point count: Sixteen inputs are configured individually for the required voltage or current signal.
  • Voltage path: Voltage channels present an input impedance greater than 1 MΩ to the connected signal source.
  • Current path: Current channels use the documented 250 Ω input path.
  • Overrange: Linear voltage ranges retain the documented ±10% overrange for measurements beyond the nominal span.

From field value to CPU data

  • A/D stage: One converter processes the module's configured analog channels at ±15-bit resolution.
  • CPU timing: Conversion is synchronized with CPU control execution to avoid a separate data-interchange delay.
  • Module update: The documented I/O-module scan time for 900A16-0103 is 100 ms.
  • Parallel modules: Additional analog modules are processed in parallel, so their presence does not serially add to this module's scan time.

Electrical separation and status reporting

  • Point isolation: Solid-state switching provides 400 V DC isolation from one input point to another.
  • Logic boundary: A 1 kV DC isolation boundary separates the field inputs from module logic.
  • Diagnostic scope: The module monitors factory calibration, the 24 V DC supply, and configuration state.
  • Status LEDs: A blinking green LED indicates scanning, while a red LED reports module or channel diagnostics.

Direct and remote field wiring

  • Direct terminal: The 900TCK-0200 Euro terminal block provides the direct field-wiring interface for 900A16-0103.
  • Remote panels: A remote termination arrangement uses two 900RTS-0001 panels for one input module.
  • RTP cables: The two remote panels connect through the 900RTC-34xx cable family.
  • Replacement record: Confirm whether the rack uses the direct terminal or RTP path before disconnecting channel wiring.
Description
Honeywell 900A16-0103 is a 16-channel high-level analog input module for ControlEdge 900 I/O. Each point can be configured for a voltage or current signal, and the module converts those field values into controller data in synchronization with CPU control execution.

All sixteen inputs on 900A16-0103 are isolated point to point, with a separate isolation boundary between the field channels and module logic. One A/D converter serves the module, producing ±15-bit values on a 100 ms update cycle while multiple analog modules are processed in parallel.

Calibration and channel configuration for 900A16-0103 are retained in non-volatile memory. Module diagnostics monitor factory calibration, the 24 V DC supply, and configuration state; a blinking green LED shows scanning, while a red LED identifies module or channel diagnostics.

Field wiring for 900A16-0103 uses the 900TCK-0200 Euro terminal block, or two 900RTS-0001 remote termination panels with 900RTC-34xx cables. This accessory relationship must be matched to the installed rack wiring before a module exchange.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can voltage and current channels be mixed on one 900A16-0103?
Yes. Each 900A16-0103 point is user-configurable for voltage or current, so record the range assigned to every channel before replacement or recommissioning.
Why does adding another analog module not double the scan time of 900A16-0103?
ControlEdge processes analog modules in parallel, while each 900A16-0103 retains its documented 100 ms module scan time synchronized with CPU execution.
What should be checked when a 900A16-0103 channel shows excessive noise?
For 900A16-0103, verify voltage or current range selection, source impedance, shielding, grounding, common-mode conditions, and the isolated channel wiring before changing calibration.
How can a technician tell whether 900A16-0103 has a module or channel diagnostic?
On 900A16-0103, a blinking green LED indicates scanning and a red LED indicates that module or channel diagnostics exist; review the controller diagnostic detail next.
What wiring hardware must match when 900A16-0103 is replaced?
Confirm whether 900A16-0103 uses a 900TCK-0200 terminal block or two 900RTS-0001 panels with 900RTC-34xx cables before moving field wiring.
Are calibration and channel settings lost when 900A16-0103 is powered down?
900A16-0103 stores calibration data and channel configuration data in non-volatile memory, but the saved controller project should still be checked against the replacement module.
Why must voltage and current source impedance be distinguished on 900A16-0103?
The 900A16-0103 voltage path is greater than 1 MΩ while the current path is 250 Ω, so the configured input type must agree with the connected field source.
