In terms of CNC bending machine, because of its own safety structure, it is impossible to completely eliminate the safety risk, in the process of material forming, if it is manually inserted and fixed workpiece, in the machine does not stop the state, must completely prevent the unnecessary movement of the press plate. It is necessary to apply other security techniques to ensure safe operation. The use of other safety components can be reduced by using the EV2D amplifier, a safe shutdown of the hydraulic valve bank in accordance with SIL3. Coupled with the analog interface, it provides the familiar EtherCat interface, which can be easily connected to the machine's control system.

 

 

The EV2D base scale amplifier is equipped with two analog signal inputs. The output signal is transmitted through two IPWM output terminals. In the extended model, there are 8 analog signal inputs and 6 IPWM outputs. Due to its extremely compact design, EV2D can fit in any switch box. It can be installed with a DIN plug.
