The Doli Elektronik EDC580, available from Hylec Controls , was developed for controlling static as well as dynamic testing instruments and is available with keyboard and display. The EDC580 features eight general purpose I4-Bus-Extension-Slots ‘on-board’ and is suitable for most precision testing machines.
The EDC580 fits hydraulic testing machines and also fits the following components:
- DC-servo motors with a capacity of 12, 160 or 320W, for this purpose there are EDC-internal amplifiers available; for DC-servo motors with 1,100 or 2,500W, there are external power amplifiers.
- Screw driven testing instruments with AC-power amplifier; these are controlled either through a digital ±10V-output or through a control output with digital Interface. All signals necessary for the control of an external power amplifier are provided by the EDC580.
- Hydraulic testing machines, which are controlled through a valve drive with ±10V. Hydraulic Testing Machines instruments are controlled with a servo valve. Slow dynamic testing machines are controlled either hydraulically/pneumatically through a servo valve or through a linear motor.
- The connection of further load cells with DMS or LVDT’s, strain transducers (single-channel or multi-channel), 2-channel-incremental-extensometers, safety shields, further I/Os, synchronising several EDC’s in a multi-channel application.
