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).

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.
