IDEC FC6A MicroSmart PLC

The FC6A MicroSmart PLC from IDEC Corporation can execute basic instructions in 0.042 µs and has a program memory of 640 KB. There are 1024 timers and six of the 512 counters are high speed at rates up to 100 kHz. These capabilities allow the PLC to handle large programs with complex control requirements such as PID, flow totalisation and recipes.

Three models are available, each with 24 VDC or 100–240 VAC power. The 16 I/O model has nine inputs and seven relay or transistor outputs. The 24 I/O model has 14 inputs and 10 relay or transistor outputs. The 40 I/O model has 24 inputs and 16 relay or transistor outputs. Each model also includes an integral 0–10 VDC analog input. The 16 and 24 I/O models can accommodate one plug-in analog cartridge and the 40 I/O model can accommodate two plug-in analog cartridges. Each cartridge has two analog I/O points — either two inputs or two outputs.

Up to 12 expansion modules can be added to the 16 I/O model and up to 15 expansion modules can be added to the 24 and 40 I/O models. These modules can be of any type, with no restrictions as to the number of analog and specialty modules. This gives the 40 I/O MicroSmart PLC the capability to handle up to 520 I/O with a maximum of 126 analog I/O.

All models have a built-in RJ45 ethernet port, supporting Modbus TCP, and an RJ45 RS232C/RS485 serial port supporting Modbus RTU.
