 Internal bus: Via the Installation Base 
 (model: R3-BSx)
 Internal power: Via the Installation Base (model: R3-BSx) 
 Power input, RUN contact output: M3 separable screw terminal (torque 0.5 N·m)
Screw terminal: Nickel-plated steel
Isolation: CC-Link to internal bus or internal power to power supply to RUN contact output to FG 
Input error data setting: Input value setting at input module error with side DIP SW
Dual communication setting: Set with the side DIP switch
Data allocation setting: Set with the side DIP switch
RUN indicator: Bi-color (green/red) LED; Green ON in normal communication; Red ON when receiving data (Function selected with DIP SW)
ERR indicator: Bi-color (green/red) LED;
Green ON or blinking at communication error (OFF with cable disconnection, blinking in setting error); Red ON at transmitting data (Function selected with DIP SW)
RUN CONTACT OUTPUT
RUN contact: Turns ON while the green RUN LED is ON (CC-Link in normal communication).
Rated load: 250 V AC @ 0.5 A (cos ø = 1)
30 V DC @ 0.5 A (resistive load)
