More Information

Overview Manuals Specifications I/O Architecture Configuration Scope Service Planning

Features:

  • Controller and direct I/O: Combines loop strategy execution with onboard field channels.
  • Signal flexibility: Supports current or voltage analog modes and two digital-input voltage ranges.
  • Safety-critical defaults: Requires engineered output states and independent interlocks where consequences demand them.
ABB IMCOM03 serves compact control duties where one rack module must both execute a strategy and interface directly with field signals.

Its termination choices determine how those channels reach the process, while board and termination settings define the electrical mode of each path.

Commissioning should prioritize output-state behavior, because a valid control strategy alone does not guarantee a safe response during reset or failure.

For ABB IMCOM03 support, provide the termination hardware, I/O signal modes, control-strategy backup and required safe-state behavior.

Description
Combining loop execution with direct field I/O, ABB IMCOM03 is an enhanced INFI 90 plug-in controller for one or two process loops. The single-board module occupies one MMU slot, runs analog and digital control strategies and communicates with INFI-NET or Plant Loop.

The field side of ABB IMCOM03 accepts four analog and three isolated digital inputs, then drives two analog and four isolated digital outputs. Its selectable 1–5 V DC or 4–20 mA analog modes and 24/125 V DC digital-input options let the termination hardware adapt the controller to established field signals.

Before configuring ABB IMCOM03, define safe output behavior for startup, RESET, STOP and failure conditions. ABB warns that digital outputs de-energize in several states, analog outputs move to user-selected values and solid-state outputs can fail on, so independent process interlocks may be required.

Technical notes
Configure ABB IMCOM03 output defaults before startup or RESET: digital outputs de-energize, while analog outputs move to user-selected values, and solid-state outputs can fail on. Provide independent process interlocks where unsafe motion or damage is possible, then confirm NTCS02 or NICS01 termination and every I/O signal mode.

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.
What happens to IMCOM03 outputs during startup or RESET?
Digital outputs de-energize, while analog outputs move to user-selected values. Those defaults must be engineered for a safe process response.
Which field signals can IMCOM03 handle directly?
The module accepts four analog and three isolated digital inputs, and provides two analog plus four isolated open-collector digital outputs.
How are analog signal modes selected for IMCOM03?
Inputs are configured at the termination unit or module, while board switches select voltage or current mode for each analog output.
How many function blocks are available in IMCOM03?
The controller provides 240 blocks; blocks 0 through 9 are fixed and block 240 is reserved, with usable capacity dependent on execution time and memory.
Which termination hardware can connect IMCOM03 to field wiring?
ABB documents NTCS02 with NKTU01 and an alternative NICS01 termination module path; the selected hardware must match the I/O signal configuration.
Can IMCOM03 replace the older NCOM03 controller?
The official instruction identifies it as a direct replacement, but field wiring, termination settings, control strategy and safe output defaults still require verification.
Why are independent interlocks important around IMCOM03?
ABB warns that solid-state outputs may fail in the on state. Separate overtravel, level, pressure or temperature protection may be needed where consequences are serious.
