Two-Line Control System: Economical & Reliable Actuator Connectivity Solution

Nippon Gear’s Two-Line Remote Control System provides a 1:1 connection between field devices and the control center. With a proven track record of over 30 years in the world’s harshest environments (such as oil and gas plants in the Middle East), this system stands out for its reliability.

The core differentiator lies in its Non-CPU (Pure Hardware) design, ensuring absolute stability and interference resistance that far exceeds conventional electronic control systems.

Outstanding Technological Advantages

1. Maximum Cabling Cost Savings

The system is intelligently designed to allow for a shared common line, significantly reducing signal cable material costs:

• Optimized Formula: Number of wires = (Number of Actuators) + 1.

• Example: To control 10 actuators, you only need 11 wires (instead of the 20 or 30 wires required by other systems). This offers immense economic benefits for large-scale projects.

2. Long-Distance Remote Control up to 5.5 KM

The system allows stable operation over very long distances, providing flexibility in locating control centers:

• 5.5 km distance: Using 2.0 mm2 cross-section cable.

• 3.8 km distance: Using 1.25 mm2 cross-section cable.

• Tolerance: Supports loop resistance up to 100 $\Omega$.

3. Rugged “Heavy-Duty” Design – Lightning & Interference Proof

Operating entirely on hardware without a CPU, the system is virtually “immune” to electrical hazards:

• Surge Protection: Absolute safety against lightning surges transmitted between lines.

• Induced Voltage Resistance: Eliminates malfunctions caused by induced voltage interference from neighboring equipment.

4. Simple Field Installation (Plug & Play)

Complex components such as the power transformer and reversing electromagnetic switch are pre-integrated inside the actuator. Field technicians only need to perform two simple steps:

1. Connect the 2 signal control wires.

2. Connect the 3-phase power supply for the motor.

Core Benefits for Investors & Engineers

• Absolute Reliability: Proven over three decades in the most extreme conditions.

• Budget Optimization: Reduces cabling and labor costs by 40-60% for multi-actuator systems.

• Continuous Operation: The Non-CPU design eliminates software crashes, ensuring the system is always ready.

• Rapid Deployment: Shortens wiring and commissioning time on-site.
