The manual generally follows the standard progression of PLC documentation from that era.
Verdict: The organization is logical but rigid. There is very little "task-based" help; you must know what you are looking for to find it.
The relay outputs on the FA2J are rated for 2A resistive, but the manual strongly advises using external fuses and flyback diodes for inductive loads (solenoids, contactors). Failure to do so welds the relay contacts shut.
Manual warning: Do not exceed 30V DC on inputs. Unused inputs must be terminated or programmed as unused.
This is where the manual shows its age and complexity.
Basic Instructions (Relay Logic): The explanations for basic contacts (NO/NC), coils, and timers are adequate. The manual uses "electrical analogy" extensively—comparing PLC logic directly to physical relay wiring. This is excellent for electricians transitioning to PLCs but can be confusing for software engineers who prefer Boolean logic explanations.
Advanced Instructions (Function Blocks):
The IDEC FA-2J is a micro/nano PLC from the 1990s–early 2000s era. It is the direct predecessor to the popular MicroSmart series. Its primary claim to fame is being one of the smallest PLCs at its time with a built-in power supply, CPU, I/O, and programmer port in a housing slightly larger than a deck of cards. idec plc fa2j manual
Target Audience (Legacy): Machine builders needing simple relay replacement, standalone sequence control, or OEM cost-sensitive applications.
Current Use Case: Only for maintaining existing machinery. Do not use for new designs (discontinued; parts scarce; software obsolete).
