Description
I/Os (Including DC Expansion Board)
The IRRInet-M DC RTU can control up to 24
DC
Solenoids (twelve outputs in the basic model
and another twelve outputs in the expanded model.)
The operating voltage can vary from 4 to 35V DC (as defined in the STS site configuration.)
The IRRInet-M also responds to back indication signals from eight different field input
sensors, four inputs on the basic model and four additional inputs on the expanded model.

Figure 4 DC Main Board I/O Connection
The IRRInet-M DC has an over-current mechanism on the voltage discharge path which
reports when an over-current (output which exceeds 10A) occurs on a specific output.
