Circuit current: Approx. 7 mA 
  Leakage current between collector and emitter 
100 µA or less 
Signal timing  When the pulse type input signals are used, the pulse width 
should be 100 ms or over. 
 
 
DI_1~DI_38 
100 ms or over 
 
 
  *  When using the system input signals as the digital input signals: 
When "Default" (standard PLC) is specified by user parameter [U11] (I/O mode), 
you can select whether INPUT23, 24, 33 ~ 38 are the system input signals or 
digital input signals. 
  User parameter [U13] 
[U13] Select input signal (Default I/O mode only) 
{Input 23,24,33,34,35,36,37,38} (0: System  1: User) 
= 1 1 0 0 0 0 0 0 
    Specify "1" for a desired bit underlined above, and appropriate system input 
signal can serve as the digital input signal.    Respective bits signify DI_23, DI_24, 
STROBE, PRG_RST, STEP_RST, CYC_RST, DO_RST and RUN when viewed 
from the left, which correspond to digital signals DI_23, 24, 33 ~ 38.
