The Modbus digital I/O Series D1700M modules provide computer monitoring of digital input and digital output signals for control of industrial devices through solid state relays.
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 will sink: 30mA (D1701/D1702), 100mA (D1711/D1712) making them ideal for controlling solid state relays. 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 D1711M and D1712M contain an onboard events counter that counts up to 10 million transitions that occur on the digital input. The event counter may be read and cleared by the host computer at any time.
The D1700 and D1700M digital I/O modules can also be mounted on a DIN-Rail using the MK-1 mounting kit.
