PC1400 Quadrature PLC

PC1400 Quadrature PLC

Product description

The PC1400provides and assortment of I/O interfaces for those difficult applications where equipment interfaces are not always straight forward. High and low side digital inputs, relay and transitor driver outputs, differential and single ended analogue inputs.

The PC1400 comes with four serial ports and 1 x Ethernet 10/100Base-T. Using the two quadrature inputs of the PC1400, the controller is able to calculate both position and direction of rotation.
