Today’s substation automation projects require RTUs that feature seamless network integration and minimized cabling. The SMP I/O, now available in rack-mount or wall-mount format, helps trim down costs and save time by reducing both required wiring and configuration.

Inputs Up to 32 binary data points; up to 24 analog data points
Outputs 2 built-in Form-C relay contacts (NC and NO); up to 16 additional relay contacts
Ethernet Communications 1 10/100BASE-TX (Standard); 1 100BASE-FX (Optional)
Serial Communications 1 rear panel RS-485 terminal block
Supported Protocols DNP3 (serial and/or TCP/IP); IEC 61850 GOOSE
Temperature Ratings -40C to 80C/-40F to 176F (Rack-Mount); -40C to 75C/-40F to +167F (Wall-Mount)
Power Supply Options 24-48 VDC; 100-250VDC/100-240VAC
Dimensions 1.72” H x 19” W x 8” L (Rack-Mount); 4” H x 11.9” W x 6.85” L (Wall-Mount)

Features

The SMP I/O is a scalable, distributed I/O module perfectly adapted to substation automation requirements.

  • Truly substation grade
  • Field-upgradeable and scalable
  • Rackmount compact enclosure fits in 1U of 19-inch relay racks
  • Minimized configuration time when used with the SMP Gateway
