DI1
DI terminal 1 Digital input DI1 to DI8 are ordinary DIs
whose response time is 10 ms.
They do no support for high‑
speed pulse input. Their input
frequency is lower than 100 Hz.
Photocoupler isolation is
supported and they are
compatible with bipolar input.
Input impedance: 3.3 kΩ
Effective level input voltage
range: 15–30 V
