PLCs, Power Supplies & Others

This relay output module provides robust switching capabilities for industrial actuators and loads. It integrates seamlessly into the Fuji Electric Micro-SX and SPH PLC platforms. The unit controls sixteen independent circuits from a single module slot. Users can drive contactors, solenoids, motors, and indicator lamps with confidence.

Output Channel Configuration and Contact Ratings

This module features sixteen normally-open relay outputs for flexible load control. Each relay handles a continuous current of 2 A at 250 V AC or 30 V DC. The total current per common terminal reaches 8 A for combined loads. Each output includes individual suppression circuits for extended contact life. The relays achieve a mechanical endurance of 20 million operations for long-term reliability.

Switching Performance and Operational Durability

The NC1Y16R-08 achieves a typical response time of 10 ms for reliable output activation. Each relay features silver-alloy contacts for superior conductivity and wear resistance. The module supports 100,000 electrical operations at full rated load. This endurance suits frequent switching applications in packaging and assembly lines. Consequently, users benefit from reduced maintenance and replacement costs. The built-in suppression circuits also minimize electromagnetic interference during switching events.

Backplane Communication and Configuration

This module communicates with the CPU through the Fuji Electric backplane bus. It automatically maps outputs to the PLC memory for straightforward programming. The unit supports both local and remote rack installations for flexible system design. Each channel includes an individual LED indicator for real-time status monitoring. These LEDs illuminate when the corresponding relay remains energized. Furthermore, the module stores no configuration parameters, simplifying replacement procedures.

Energy Consumption and Power Requirements

The module draws 50 mA at 5 V DC from the backplane for internal logic. External power for relay coils comes from the field supply via dedicated terminals. The total power consumption depends on the number of energized outputs. Each relay coil requires approximately 0.5 W at 24 V DC. Power dissipation remains below 4 W under full operational load. This efficiency reduces heat accumulation inside the control cabinet.

Installation and Wiring Accessibility

This module features a removable terminal block for convenient field wiring. Installers can pre-wire the connector before inserting it into the rack slot. The unit accepts wire gauges from 0.2 mm² to 1.5 mm² for flexible installation. A secure locking mechanism prevents accidental dislodgement during vibration. Furthermore, the housing carries an IP20 rating for protection against solid objects. This rugged design suits conveyor systems, packaging machinery, and material handling equipment.

Environmental Tolerance and Mechanical Durability

The module operates reliably across a temperature range from 0 °C to 55 °C. It withstands humidity levels between 10% and 90% without condensation issues. Vibration resistance reaches 0.75 g from 10 to 57 Hz for industrial environments. The unit also tolerates shock up to 15 g for 11 ms duration. These specifications guarantee stable performance in demanding factory conditions. The robust construction ensures years of trouble-free service in continuous production lines.
