The Extension Units LX2N is a series of digital input/output modules manufactured by Mitsubishi Electric. These units offer 32 or 48 input/output points, with a choice of relay or transistor output types. The modules are compatible with the HCFA LX 1N/LX2 and LX3 series.

The LX2N series also offers several special features, including LEDs for indicating the input and output status, detachable terminal blocks, and an integrated service power supply with 250 mA or 460 mA capacity, depending on the specific model. The detachable terminal blocks allow for easy installation and maintenance, while the integrated service power supply ensures reliable operation.

The LX2N series extension units can be used in a variety of applications, including process control, factory automation, and building automation. They provide a cost-effective solution for expanding the input/output capacity of a programmable logic controller (PLC) or other automation system.

These are additional components that can be used with the HCFA LX series programmable logic controllers (PLCs).

The Extension Blocks LX2N provide either 8 or 16 additional input/output points and can be used with either relay or transistor output type. They have LEDs to indicate input and output status, and are compatible with the HCFA LX 1N/LX3G and LX3U series.

The Extension Units LX2NC are similar to the Extension Blocks LX2N, but are designed to be used only with LX 3UC series base units. They provide either 16 or 32 additional input/output points and have removable terminal blocks. They are also compatible with the HCFA LX 1N/LX3G and LX3U series.

The LX2N-2DA, LX2N-4DA, and LX3U-4DA are analog output modules that provide 2 to 4 analog outputs. They convert digital values from the LX 1N/LX 3G/LX 3U controller to the analog signals required by the process. They can output both current and voltage signals, and the LX3U-4DA can only be used in combination with a LX3G/LX3U series base unit.
