A IN610 Digital Input/Output Interface Module
NOTE: The DIO Interface Module may not be available for some models.
Please contact your Federal Signal/Sirit Representative for availability.
The Sirit DIO Interface Module provides an easily accessible interface to the
reader’s four digital inputs and four digital outputs. Screw terminals provide
secure signal connections and eight LEDs indicate I/O activation. The
interface also provides +12 Vdc, +15 Vdc, and ground.
The module connects to the reader’s existing digital I/O connector and 15
Vdc power connector. Reader power passes through the interface module.
