Specification

SEODescription

The Mitsubishi FX-16EX-A1-TB/UL is a compact 16-point input expansion module designed for industrial automation systems. Part of the FX Series PLC family, it features a built-in terminal block (UL-certified) for simplified wiring, supporting 16 DC input channels with a 24 VDC operating voltage range (±10%). This module connects directly to a master PLC unit, such as the FX3U or FX5U series, via a dedicated extension cable, allowing seamless integration into control systems. It operates within a temperature range of 0–55°C and is ideal for manufacturing, packaging, and machinery applications requiring reliable I/O expansion. Key advantages include its space-saving design, compliance with UL standards, and tool-free terminal connections. However, it lacks standalone functionality, requiring a master PLC for operation, and does not include built-in communication ports for external networking. The FX-16EX Terminal Block UL variant ensures compatibility with safety-critical environments.
