The 1700 series digital I/O products provide computer monitoring of digital input and digital output signals and control of industrial devices through solid state relays.
The D1700 digital I/O modules allow a single host computer to control thousands of I/O points from one serial port. The digital inputs accept a wide signal level input, up to +30Vdc without damage, and have TTL logic input switching levels. The digital outputs are open-collector transistors offering the most flexibility for almost any application. The digital outputs will also sink: 30mA (D1701/D1702), 100mA (D1711/D1712), making them ideal for controlling solid state relays.
The H1700 digital I/O boards provide direct interface to industry standard mounting racks and solid-state relays. Industry standard mounting racks can be controlled directly with the H1750 or H1770 digital I/O boards.
The 1700M Modbus series is also available. It is similar to the 1700 Series but communicates using the Modbus RTU protocol.
The status of digital inputs and digital outputs are communicated to any host serial port in ASCII using either RS-232 or RS-485.
The D1700 digital I/O modules can also be mounted on a DIN-Rail using the MK-1 mounting kit.
