SFAR-S-8DI8DOAbout the product SFAR S 8DIDO has8x DI(Digital Inputs) and 8x DO (Digital Outputs). Digital Inputs can work as fast pulse counter up to 1 kHz and support PNP or NPN input types. Digital Outputs are PNP transistor outputs with maximum load 500 mA, 30 V DC. All inputs and outputs are isolated from RS85 and power supply with use of optical isolators. Built in RS485 interface allows to easy connection over Modbus RTU ASCII protocol with a PLC makes the
