Name: Interface Relay Module FY-T73 16C - Geya Electrical
SKU: FY7316C

Description

The FY7316C 16 Channel Relay Terminal Block is the ultimate solution for large-scale industrial automation. Designed as a professional PLC output load current amplification and isolation board, it integrates 16 independent relay channels into one highly efficient module. Unlike standard DIY relay boards, this industrial-grade unit features a flame-retardant housing and a built-in DIN rail mount, ensuring your delicate PLCs and microcontrollers (5V or 24V systems) are fully protected from electrical surges while driving heavy industrial loads.

Core Industrial Applications

Massive Centralized Control: Simultaneously manages up to 16 independent circuits. Ideal for complex CNC machining centers, extensive automated packaging lines, and advanced smart building control panels.
Maximum Space Optimization: The ultra-high-density 16-channel layout drastically reduces wiring clutter and saves significant DIN rail space compared to installing individual relays.
Signal Isolation & Amplification: Safely amplifies weak control signals to drive high-power equipment (valves, motors, contactors) while maintaining strict electrical isolation for the main controller.

Advanced Features & Build Quality

Engineered for maximum reliability in demanding environments, the FY7316C supports both NPN and PNP input signals. Available in 5V and 24V coil voltage options, it caters to standard industrial power supplies. Every single channel is equipped with a dedicated LED status indicator for instant visual monitoring and rapid troubleshooting.

Equipped with premium MPA electromagnetic relays (CCC, TUV, UL certified) for exceptional mechanical and electrical longevity.
Secure screw terminal blocks designed for stable, vibration-resistant wiring (supports 0.2~2.5mm² cables).
Universal DIN rail mounting base compatible with standard TS15, TS28, and TS35 rails.
High dielectric strength rated at 2.5KV, 50Hz for 1 minute, ensuring superior physical electrical isolation.

Frequently Asked Questions (FAQs)

1. Why should I choose a 16-channel relay block over individual relays?

The FY7316C offers massive space savings and drastically reduces wiring time. Instead of mounting and wiring 16 separate relays, this single module snaps onto your DIN rail and provides a centralized, clean, and highly organized control hub for large automated systems.

2. How do I choose between the 5V and 24V versions?

Select the voltage based on your primary controller’s output. If you are using standard industrial PLCs (like Siemens, Mitsubishi, or Allen-Bradley) which typically output 24V, choose the 24V version. If your system relies on 5V microcontrollers or specific logic boards, select the 5V version.

3. What are the dimensions of this 16-way module?

Despite housing 16 independent channels, the FY7316C is highly compact, measuring 250 × 85 × 43.5 mm. It is designed to fit perfectly on standard 15mm, 28mm, or 35mm DIN rails inside professional control cabinets.

4. Is it compatible with both NPN and PNP signals?

Yes! The module is universally compatible with both NPN (sinking) and PNP (sourcing) input signals. You just need to wire the common terminal appropriately (common anode for NPN, common cathode for PNP) based on your PLC’s specifications.

5. What is the maximum load each of the 16 channels can handle?

Every single one of the 16 channels operates independently and can safely switch loads up to 10A at 250VAC or 30VDC. This is ideal for controlling multiple solenoid valves, contactors, motors, and industrial lighting simultaneously.

6. How can I monitor the status of all 16 channels?

To make maintenance and troubleshooting as easy as possible, the FY7316C features 16 individual LED status indicators. You can instantly see which specific channels are active without needing to test the circuits manually.
