Sensor-Technik WiedemannESX-Micro programmable logic controller
Upon request
The freely programmable small-sized controller ESX-Micro works independently as a measuring, driving, or controlling device for electro-hydraulic system management and is capable of executing a number of separate or related tasks in real time. The ESX-Micro was developed especially for use under harsh conditions and extreme temperatures, funtioning from −40 °C to +85 °C in vehicles and machines.
All inputs and outputs are protected against short circuit to ground or to voltage overload, and have a built-in diagnostic capability.
Proportional valves can be driven without expensive amplifier or controller cards. Either a PWM (pulse width modulated) output with internal current detection or a special output for proportional valves with integrated circuitry may be used.
A robust cast aluminum housing (IP65, optionally IP67) with a Gore-Tex breathing filter offers high immunity to electromagnetic disturbances and protects against mechanical stressing.
