Distributed Discrete I/O

The rugged NovaTech Distributed Discrete I/O Module (DDIO) can help reduce wiring and costs in substation monitoring and control applications. Its hardened design, small form factor, and distributed communications capability allow it to be installed virtually anywhere in the substation. DDIO modules can be wired back to any RTU or PLC supporting the DNP3 protocol using an RS- 232, RS-485, fiber optic or Ethernet connection. Combinations of up to 24 inputs or outputs are provided to meet specific requirements. The DDIO also offers high resolution (1ms) time-stamping, an IRIG-B port, and independent input circuits in an enclosed package. Customized input and output labels can be inserted into the front panel. The DDIO, along with the Distributed Combination I/O module (DCIO), provides security features to meet NERC CIP requirements, including strong passwords, user groups, encrypted protocols and firewall.

Operating Temperature Range -20 to +70oC; Tested to IEEE C37.90.1, 2 and 3 surge

Communication Protocol Configuration DNP3 to module for status and control. Unsolicited Report-by-Exception (URBE) supported; Set Time on module supported; Serial baud rate set up to 57.6kb, Ethernet 10/100M Baud rate. Simple Mode: Set address and comm parameters with DIP switches. Advanced Mode: Set advanced comm parameters through webpages served from module
