Pulse Input (/PM1)
Item Specifications
Pulse input
Number of inputs 3 (8 when using the remote control input terminals)
Input type Isolated from the main circuitry through a photocoupler and built-in isolated power supply for the
input terminals.
Shared common for pulse inputs.
Input type and signal level V
oltage-free contact Contact closed at 200 Ω or less and contact open at 100 kΩ or greater
Open collector ON voltage: 0.5 V or less (sink current 30 mA or more), leakage current when
OFF: 0.25 mA or less
Counting
Counts the rising edges of pulses.
For voltage-free contact input: Contact ope
n to contact close
For open collector: Voltage level of the terminal H from high to low
Allowable input voltage 30 VDC
Max. sampling pulse period 100 Hz
Minimum detected pulse width
5 ms or more for both low (closed) and high (open)
