Product Summary
The Flexem FR-D0808N digital mixed I/O module delivers 8 bidirectional inputs and 8 NPN transistor outputs. It operates at 24VDC with an input range from 0 to 28.8V. Each input channel draws exactly 7mA while each output group handles up to 0.5A. The module measures just 18mm wide, 111mm tall, and 76mm deep. This ultra‑slim design saves valuable panel space in any control cabinet.
Buyer Guide: Selecting the Right Output Type
Procurement engineers must match output type to the load polarity and wiring system. The FR-D0808N uses NPN sinking outputs that switch the ground path for each load. This configuration suits systems where the load common is connected to positive voltage. Typical applications include PLC input modules and relay coils in common positive networks. In contrast, the FR‑D0808P offers PNP sourcing outputs for common negative systems. By choosing the FR-D0808N, you ensure direct compatibility with NPN‑driven devices and avoid extra interface hardware.
Input Flexibility for Any Sensor
The FR-D0808N accepts both NPN and PNP sensor signals on all eight input channels. This bidirectional capability eliminates the need for external signal converters. You can freely mix sensor types without additional wiring complexity. The rated input voltage is 24VDC but the module tolerates a wide range from 0 to 28.8V. Each input draws only 7mA, minimizing power consumption and heat generation. This flexibility simplifies inventory management for your facility.
Output Current and Grouping Architecture
Each NPN output channel can sink up to 0.5A continuously. The module groups outputs with a shared current limit of 0.5A per group. You must distribute loads carefully across groups to prevent exceeding this threshold. This grouping protects against overcurrent conditions while allowing dense wiring. The architecture ensures reliable operation even in high‑density automation panels. Always verify total group current during system design.
Mechanical Fit and Installation Workflow
The FR-D0808N occupies only 18mm of DIN rail width and weighs just 65g. Its compact dimensions reduce shipping costs and simplify installation in tight enclosures. Mount the module on a standard 35mm DIN rail by clipping it into place. Connect the screw‑less spring terminals using a small screwdriver for fast wiring. The module supports daisy‑chain power wiring to adjacent units. This design accelerates panel assembly and reduces labor time.
Comparative Analysis: FR‑D0808N vs. FR‑D0808P
Both modules share identical input specifications: eight bidirectional channels, 24VDC rated voltage, 0–28.8V range, and 7mA per input. The only difference lies in the output transistor type. This single distinction dictates which load polarity each module can drive. Below is a focused comparison for procurement managers.
- FR‑D0808N – NPN (sinking) outputs. Use this when your load common is positive. This is common in Asian and European machine designs.
- FR‑D0808P – PNP (sourcing) outputs. Use this when your load common is negative. This is common in North American control systems.
Selecting the wrong output type forces costly level shifters or rewiring. Always verify your load polarity and PLC input type before ordering. The FR-D0808N excels in systems using NPN sensor inputs and NPN actuator outputs. This creates a homogeneous signal chain with minimal components.
Procurement Checklist for FR‑D0808N
1. Confirm your control voltage is 24VDC and within 19.2–28.8V.
2. Verify output load current per channel does not exceed 0.5A.
3. Ensure total current per output group remains at or below 0.5A.
4. Choose FR-D0808N if your system requires NPN sinking outputs.
5. Reserve 18mm of DIN rail width per module in your panel layout.
