ComAp InteliGen Series Technical Notes

The Evolution of InteliGen Architecture

The InteliGen platform originated in the early 2000s as ComAp's response to the growing demand for networked, multi-genset control in industrial standby and prime power applications. The first-generation IG-NT controllers introduced a 32-bit processor core, a backlit LCD operator interface, and a proprietary CAN-based inter-module bus (IB-Lite). Hardware revision milestones are significant for compatibility: HW version 1.x units use a specific backplane connector pinout and firmware branch (FW 1.x) that is not forward-compatible with HW 2.x firmware. The IG-NTC variant (the C denoting the compact or cost-optimized configuration) was introduced to address mid-range applications where the full IG-NT feature set was not required, while retaining the same physical form factor and communication bus. The HW version 1.3-TO designation indicates a specific board revision with a terminal output (TO) configuration, relevant for replacement sourcing. Later generations — InteliGen 200, InteliGen 500, and the current InteliGen NT GPRS/4G variants — introduced Ethernet, USB, and cellular connectivity, but retain backward-compatible I/O expansion slots for IG-IOM and IG-BIO modules. Understanding hardware revision compatibility is critical when sourcing replacement units: a HW 2.x controller cannot directly substitute a HW 1.x unit without firmware reconfiguration and potential I/O remapping.
