This compact unit features 16 bipolar input channels that accept both NPN and PNP sensor types. Its slim 18mm width saves valuable cabinet space while providing sixteen individual status indicators.
Theme A: Procurement Guide for Engineers
Selecting the Right Digital Input Module
Engineers must match input modules to their sensor types and field wiring. The FR-D1600 solves compatibility issues by supporting both NPN and PNP signals on every channel. This flexibility reduces inventory complexity and simplifies system design.
Procurement managers value the module’s standardized 35mm DIN-rail mounting. This feature ensures quick installation into existing control panels without special brackets. The compact dimensions of 111mm by 18mm by 76mm allow high-density layouts.
The module’s 65-gram weight minimizes mechanical stress on the DIN rail. Sixteen individual red LED indicators provide immediate visual feedback for each channel’s status. This diagnostic capability speeds up troubleshooting during commissioning and maintenance.
Key Technical Specifications for Buyers
Every channel on the FR-D1600 supports bipolar input configurations. This NPN and PNP compatibility means the module works with proximity sensors, limit switches, and photoelectric eyes. The sixteen-point density suits medium-scale automation cells perfectly.
The unit draws power from the backplane bus, eliminating separate wiring runs. Its industrial design withstands typical factory floor conditions without active cooling. The lightweight aluminum housing dissipates heat effectively across the entire assembly.
Theme F: Deep-Dive Technical FAQ
What sensor types work with the FR-D1600?
The FR-D1600 accepts both NPN sinking and PNP sourcing sensors. Each of the sixteen channels independently handles either type without jumper changes. This universal input capability simplifies wiring for mixed-sensor applications.
How do I mount this module in my panel?
Mount the FR-D1600 onto a standard 35mm top-hat DIN rail. Press the module onto the rail until the locking clip engages securely. The 18mm width allows side-by-side placement with other Flexem I/O modules.
What do the sixteen indicators show?
Each indicator lights up when its corresponding channel detects an active input signal. The bright red LEDs are visible from several meters away. This real-time status display helps operators verify sensor operation instantly.
Can I mix AC and DC signals on this module?
The FR-D1600 handles only DC digital input signals from industrial sensors. Do not connect AC voltages or analog signals to these terminals. Always verify sensor output types match the module’s DC input specifications.
What are the module’s exact physical dimensions?
The FR-D1600 measures exactly 111 millimeters in height, 18 millimeters in width, and 76 millimeters in depth. Its total weight is precisely 65 grams. These compact dimensions enable dense I/O layouts within standard enclosures.
