ComAp InteliLite 4 AMF 25

Single-generator AMF controller

InteliLite 4 AMF 25 manages one standby or prime-power generator. Its built-in isolated RS-485 port makes it a useful starting point for generator monitoring. Ethernet is an optional communication module, rather than a standard socket on every controller.

Compatibility

Documented Modbus RTU and TCP interface

Integrated RS-485 for Modbus RTU; optional Ethernet communication module for Modbus TCP

The AMF 25 has onboard RS-485. The AMF 20 needs a communication module for this serial path. Select modules by the controller order code, not by front-panel appearance.

AccuracySupported with conditions
The documentation identifies electrical and operating measurements for this plant role. CT configuration and measurement location determine how those values are used.12
SecurityNot yet assessed
The cited documentation does not establish an authenticated, encrypted Edge monitoring connection.
ReliabilityNot yet assessed
The controller application distinguishes operating conditions and alarms. Retain communication availability alongside the plant readings.
RuggednessSupported with conditions
IP65 front panel and IP20 rear; standard operating temperature -20 to +70 °C.2
ScalabilityNot yet assessed
Assign one device identity per controller and keep generator, mains and busbar measurements separate.
LifecycleSupported with conditions
Retain the exact model documentation and configuration when replacing a controller or communication module.12

Setup

  1. In InteliConfig, save the application file, select the monitoring port and export the configurable Modbus table.

    Keep the table with its value names, addresses, types and scaling beside the Edge point list.

  2. Record CT ratios and the physical measurement location.

    Compare the first electrical values with the controller display before using them in totals or trends.

  3. Keep missing responses distinct from a stopped generator.

    Store communication availability beside running state so a disconnected cable does not look like healthy standby.

  4. Build a read-only point list for monitoring.

    Remote start, synchronisation and breaker operation require a separate control design with the existing panel interlocks and feedback.
