Electronica's EL400 digital readout (DRO)

The DRO comprises a rugged die-cast housing; a bright LED display, with wide viewing angle, that can be seen clearly in all light conditions; and a tactile keypad, with keys rated up to 15 million operations.The keypad also provides dedicated, one-touch axis zero keys. The DRO only needs to be set once for any specific group of parameters, the information can then be transferred to a PC ready for input via USB to any other DROs acquired. As standard, the EL400 can interact with any TTL/RS422 industrial standard encoders based on IP67 magnetic or glass scale/optical technology, or a mixture of encoder types on different axes. Other industrial interfaces such as 11 micro Amp, 1 Vpp and a variant suitable for analogue ball-scale inductive technology, are also available. The EL400 allows for direct connection of both 5 mm and 12.7 mm ball encoders, with 9-pin D-connectors, and older round pin encoder systems, with an adaptor cable. A probe interface is included as standard on the DRO and a cost effective contact probe, that allows basic alignment and datum setting, is also available. Designed for turret mill type applications, the 4-axis milling machine variant facilitates the internal summing of both knee and quill axes; with users able to view either the knee or quill axis, or the sum of both. A range of lightweight DRO stands is available or the EL400 can be panel mounted if required.
