The Shinko Electric C7-15T is a specialized “Twin Controller” unit designed for the synchronous management of dual-axis electromagnetic vibratory feeders. This controller is widely recognized in the bulk material handling industry for its ability to provide precise, independent, or linked control of vibration intensity for two separate feeding units from a single compact module.
Product Parameters (Datasheet)
- Model Number: C7-15T

- Input Voltage: 100V / 200V AC (Auto-switching or terminal selectable)
- Frequency: 50/60 Hz (Dual compatible)
- Output Current: Max 1.5A per channel (Typical for the C7 series)
- Control Method: Phase-angle control via Thyristor/SCR
- Output Voltage Range: 0 to 95% of input voltage
- Soft Start Time: Adjustable (typically 0.2 to 2.0 seconds)
- External Control: Support for external volume (potentiometer) or 4-20mA / 1-5V DC analog signals
- Ambient Temperature: -10°C to +50°C
Country of Origin
This control equipment is designed and manufactured by Shinko Electric Co., Ltd. (now widely known under the Sinfonia Technology brand) in Japan.
Application Fields
The C7-15T is a critical component in automated weighing and packaging lines:
- Food Processing: Controlling twin-lane vibratory trays for snacks, grains, or frozen vegetables.
- Pharmaceuticals: Managing the flow of tablets or capsules into bottling machines.
- Chemical Industry: Precise dosing of granular materials into mixing vats.
- Parts Feeding: Synchronizing dual bowl feeders for assembly line components.
- Hardware Packaging: Feeding bolts, nuts, and washers into counting systems.
Product Usage Instructions
- Mounting: Install the controller in a vertical orientation within a dust-proof control panel to ensure proper heat dissipation from the internal power components.
- Voltage Selection: Before applying power, verify the internal jumper or terminal settings match your local supply (100V or 200V).
- Load Connection: Connect the electromagnetic coils of the vibratory feeders to the “Output” terminals. Ensure the total current draw does not exceed 1.5A per side.
- Tuning: Use the “Main Volume” dial to set the base vibration amplitude. Adjust the “Sub-Volume” or trim-pots to balance the feed rate between the two channels.
- Soft Start Adjustment: Set the soft-start dial to prevent “hammering” or sudden surges of material when the feeders are energized.
Product Technical Description
The C7-15T utilizes a phase-angle control circuit based on high-reliability thyristors. By clipping the AC waveform, the controller regulates the effective power sent to the electromagnetic coils of the feeders. The “Twin” architecture means the board contains two identical but independent power stages. This allows a single operator to manage a “Rough Feed” and “Fine Feed” cycle simultaneously, or to balance two parallel production lines with high accuracy. The inclusion of internal noise filtering helps prevent interference with nearby sensitive electronic sensors.
Q&A (Common Questions)
Q: Can I use this controller for a single large feeder instead of two small ones? A: No, you should not bridge the outputs. Each channel is rated for its own maximum current. For larger feeders, you should move to a higher-capacity single controller like the C10 series.
Q: Why is my feeder humming but not moving material? A: This often indicates the output voltage is too low to overcome the spring tension of the feeder, or the frequency setting (50/60Hz) on the controller does not match the mechanical tuning of the feeder tray.
Q: Does this unit support remote Start/Stop? A: Yes, there are dedicated dry-contact input terminals that allow a PLC or foot switch to enable or disable the vibration without cutting the main power.
Q: What is the difference between Shinko and Sinfonia? A: Shinko Electric rebranded to Sinfonia Technology Co., Ltd. The C7-15T is the same high-quality design regardless of which brand name appears on the label.
