The industrial counter/tachometer LD is a cost-effective large display for pulse signals. It is designed with a robust aluminum housing and a high protection rating of IP 65 for harsh industrial use. The input frequency is up to 25 kHz and can be adapted to almost all commercially available sensors. The device is freely scalable and easy to program via front buttons. It offers a counting function as a pure piece counter or as a counter with phase discrimination/totalizer, as well as a tachometer with period duration measurement. Additionally, it features two freely programmable relay outputs. The projection of the device is quick and secure directly via three buttons or software.
