MODEL: R3-DAC16
Remote I/O R3 Series/C03: Rubber coating

DISCRETE INPUT OUTPUT MODULE

CAUTION(Di 8 points, Do 8 points)
Typical Applications• Controls start/stop of field devices with ON/OFF controloutput• Simplifies signal hold circuit of field devices• Utilizing One-Shot Output reduces the load of PLC side.

• This unit is not designed to be used with the following
types of interface modules (models: R3-NC2, R3-NEIP1, R3NFx, R3-NLx).
• Output completion status data is compatible with interface
modules (models: R3-NC1, R3-NC3, R3-NDx, R3-NE1, R3NFL1, R3-NM1, R3-NM4, R3-NP1) of firmware version V2.00
or higher, and interface modules (models: R3-NM3, R3NML3) of firmware version V1.00 or higher.
