The EP1816-3008 EtherCAT Box is an I/O system with built-in tilt monitoring in longitudinal and transverse directions. This compact, IP 67-rated measuring device has two integrated 3-axis acceleration sensors and 16 digital inputs. Capable of operating in harsh environments, it can be used to implement acceleration and angle measurement directly in the field, outside of protective electrical cabinets.
The EtherCAT Box features two integrated 3-axis, 16-bit acceleration sensors with resolution options of ±2 g, ±4 g, ±8 g and ±16 g. The sampling frequency is 1 Hz to 5 kHz. These MEMS (micro-electronic mechanical) systems are based on forked silicon structures, which have movements or vibrations that result in a capacitive change and a corresponding signal value.
A typical application for the 3-axis acceleration box is vibration and shock/oscillation monitoring of machines. For example, vibrations of robot arms can be precisely monitored through the acceleration measurements. For wood sawing machines, an EP1816-3008 mounted on the worktable reliably monitors the saw-blade angle adjustment through fast signal acquisition over EtherCAT.
The signals are available directly in the main control system rather than managed with stand-alone measurement systems. The two sensors, which are arranged at 90° angles, make the EP1816-3008 a redundant measuring system.
