Compact Mixed I/O for Space-Constrained Panels

The FUJI NR2DY-32T05DT digital I/O module combines both inputs and outputs in a single compact housing. This unit saves valuable panel space by eliminating separate input and output modules. Small to medium control systems benefit from this efficient space-saving design.

I/O Specifications and Electrical Ratings

This digital I/O module provides 16 sinking inputs and 16 sourcing outputs in one unit. The inputs accept 24 V DC signals with a nominal current of 7 mA per channel. Each output switches up to 0.5 A at 24 V DC with short-circuit protection. Furthermore, the module includes a common power supply terminal for both input and output circuits.

Input Circuit Design and Signal Handling

The FUJI NR2DY-32T05DT uses opto-isolators for each input channel, protecting the CPU from external disturbances. An integrated RC filter suppresses high-frequency noise on the input lines. The module also includes LED indicators for each input and output channel, simplifying visual status checks.

Output Protection and Diagnostic Features

Each output channel includes short-circuit protection that limits the current to 0.7 A. Thermal shutdown activates at 85°C to prevent damage from overloaded channels. A common fault relay activates upon overcurrent or overtemperature conditions. These protective measures ensure reliable operation in demanding industrial environments.

Installation and Connection Interface

This digital I/O module features a compact 50 mm housing that fits standard Micro-SX racks. The unit weighs approximately 0.25 kilograms, allowing straightforward installation. A 40-pin connector provides access to all I/O terminals and the common supply. Spring-clamp terminals accept wires from 0.2 mm² to 1.5 mm² for secure connections.

System Integration and Addressing

You can install this I/O module in any slot of the Micro-SX central or expansion rack. The module maps its 16 inputs and 16 outputs to consecutive addresses in the I/O table. Users can configure input filters and output default states through the programming software. The module supports hot-swapping for quick replacement without system shutdown.

Application Guidelines and Environmental Ratings

This I/O module operates reliably from 0°C to 55°C with an IP20 protection rating. For output connections, use appropriate wire gauges to handle the rated current. Always connect the common supply terminals correctly for proper input and output operation. The module meets CE standards for industrial control equipment.
