General Info

Basically – looking at it from the technical side – the EDC222V complies with the EDC220V (“on-board” measuring channels for the control of basic testing instruments, “on-board” load channels with ±180,000 steps, output channel to control an actuator, two I2-Bus-Extension-Slots). But it has a desk top case just as the EDC58V0 and therefore is available with display and keyboards and with the same drive variations as the EDC580V. This unit is for use with hydraulic machines

The EDC222V fits for:
• DC-servo motors with a capacity of 12, 160 or 320Watt, for this purpose there are EDC-internal amplifiers available. For DC-servo motors with 1,100 or 2,500Watt there are external power amplifiers.
• Screw driven testing instruments with AC-power amplifier. These are controlled either via a digital ±10-Volt-output or via a control output with digital Interface. All signals necessary for the control of an external power amplifier are provided by the EDC.
• Hydraulic instruments which are controlled via a valve drive with ±10-Volt.
• Hydraulic instruments, which are controlled with a servo valve.
• Slow dynamic testing instruments, which are controlled either hydraulically/pneumatically via a servo valve or via linear motor.
• the connection of further load cells with DMS or LVDTs, strain transducers (single-channel or multi-channel), 2-channel-incremental-extensometers, safety shields, further I/Os, synchronising several EDCs in a multi-channel application. For these nearly unlimited applications further options are needed!
