Product Details

JTEKT ECA-0302D Electromagnetic Valve Control Amplifier

Brand:JTEKT (formerly known as TOYOOKI Fengxing)

The JTEKT ECA-0302D solenoid valve control amplifier is an industrial grade control module designed specifically for precise control of solenoid valves under the JTEKT brand. It relies on the brand's technical accumulation in the field of precision electromechanics and is compatible with various types of solenoid valves. It is widely used in automation production lines, machine bed equipment, hydraulic and pneumatic systems, and other scenarios. Its core function is to amplify, convert, and stabilize control signals, achieve precise start stop, flow regulation, and status monitoring of solenoid valves, and ensure the stability and response speed of the entire control system.

1、 Core parameters of the product

As a specialized control amplifier, ECA-0302D is designed with parameters that meet the stringent requirements of industrial scenarios. The core specifications are as follows (based on the JETTEKET industrial control product standards and reference to similar model parameter specifications):

input signalSupports analog input (4-20mA/0-10V), compatible with various control signal sources such as PLC and sensors, input impedance ≥ 10k Ω, high signal sampling accuracy, strong anti-interference ability, and can accurately capture weak control signals.
output signalThe output type is current output (adjustable from 0-500mA), suitable for DC solenoid valves (commonly used specifications for DC24V), with small output ripple and high stability. The output current can be linearly adjusted according to the input signal to achieve stepless adjustment of the solenoid valve.
power supply voltageDC24V (± 10%) wide voltage adaptation, suitable for common power supply environments in industrial sites, low power consumption (no load ≤ 1.5W), energy-saving and reducing equipment operating costs.
working environmentWorking temperature -10 ℃~60 ℃, relative humidity ≤ 85% (no condensation), protection level IP20 (panel installation), can adapt to temperature and humidity fluctuations in industrial sites, and avoid equipment failures caused by environmental factors.
response time：≤10ms， Quickly respond to control signals, reduce electromagnetic valve action delay, improve the synchronization of the entire control system, especially suitable for high-frequency start stop work scenarios.
structural specificationsAdopting a compact panel installation design, it has a small volume (conventional size is about 80 × 50 × 30mm, subject to the actual product), easy installation, saves internal space of the control cabinet, and adapts to various installation layouts.

2、 Working principle

The core working logic of ECA-0302D solenoid valve control amplifier is "signal conversion amplification stable output", combined with the principle of solenoid valve control to achieve precise control. The specific process is as follows:

Signal input: Receive control signals (analog 4-20mA/0-10V) from devices such as PLC, encoder, sensors, etc., which correspond to the target action of the solenoid valve (such as start stop, flow regulation).
Signal processing: Internally integrated high-precision signal conditioning circuits filter, amplify, and linearly correct input signals, filtering out electromagnetic interference, voltage fluctuations, and other clutter in industrial sites to ensure signal stability and accuracy.
Current amplification: Amplify the processed weak current control signal into a strong current signal (adjustable from 0-500mA) that can drive the solenoid valve, solving the problem of weak current signals not directly driving the solenoid valve coil.
Feedback and protection: Some models integrate signal feedback function, which can feed back the actual working status of the solenoid valve (such as on/off, current size) to the control end for real-time monitoring; At the same time, it is equipped with overcurrent, overvoltage, and short-circuit protection circuits. When the output current is abnormal or the circuit is short circuited, it automatically cuts off the output, protecting the amplifier, solenoid valve, and the entire control system from damage.

The core of its work is to control the magnetic field strength of the solenoid valve coil through precise current regulation, and then drive the valve core to move, realizing the on/off or flow regulation of fluid (gas or liquid), which fits well with the core control logic of solenoid valve "electromagnetic force → mechanical motion → fluid control".
