EDM-M* - 数字放大器,用于开环比例阀

EDM-M*型卡是一种用于开环比例阀控制的数字放大器。其设计符合导 轨式安装形式:DIN EN 50022。

该单元提供和参考输入信号成比例的可变电流,不受温度变化或者负载 阻抗的影响。

电磁铁电源的PWM特性减小了阀的滞环,从而优化了控制精度。该单 元可提供三种主要形式,可控制单电磁铁阀(M1),双电磁铁阀(M2) 和 两个独立通道控制两个单电磁铁阀(M3)。每个形式均可根据相应的阀, 优化定制各种不同的最大电流规格和开关频率(PWM)。

参数调节可通过前面板上的按键和显示完成,或者通过RS232 或USB 转换器(EDMPC/20 软件),连接笔记本电脑实现。

 
 

EWM-RL- 闭环系统数字式快/慢速控制卡

This card is designed to control proportional valves with one or two solenoids, with the current output controlled in open loop.

The card moves the proportional valve via preset value input. Eight demand value input can be activated in binary mode, so it is possible to control speed, directional and ramp values without any analog card into the PLC.

The card use the RS232C interface, and is settable via notebook, using the kit (EWMPC).

EWM-A-PV- Universal amplifier for proportional valves

 

This card is designed for proportional valves control: directional, pressure or throttle valves. Current output controlled in closed loop.

— Function control mode as parameter to be configured:
- for dual solenoids proportional valves,with analogue command signal ±10V or 4÷20 mA.
- for one or two single solenoid proportional valves (throttle, pressure, directional..), with analogue input signal 0 ÷10V or 4 ÷20 mA.
- for proportional valves, single or dual solenoids either, with pre-programmed values, selectable by 3 digital inputs.

—  Card setup via software only, through an on-board USB-B port.
