3.4 I/O-AC Module
The I/O-AC Module (see Figure 3-4) manages two digital inputs (Dry Contact type) and 14
outputs (AC Triacs).
The I/O-AC Module should be located in the slot designated by the Site Configuration file
in the Programming ToolBox.
To operate the solenoid valves connected to the module, an external power source of 24
VAC must be directly connected to the module. The 24 VAC power source also enables
the operation of the Digital Inputs.
The number of solenoid valves, connected to the module, can be limited by the software.
The software indicates the maximum number of solenoids to operate properly. This
limitation can be set per module and per IRRInet XL RTU.
Each valve is energized separately to avoid the inrush current influence.
The module is protected by an on-board replaceable 4.0 Amp fuse (p/n: 6502069C09).
