Output specications
Item Specications
Signal name Output (Y0-Y7)
Output polarity Source output (high level output
,
PNP type)
Control circuit voltage DC 5 V to 24 V
Rated load current 0.1 A/channel
,
0.5 A/COM
Max. voltage drop upon ON 0.2 V (typical value)
Leakage current upon OFF Below 0.1 mA
Output frequency 200 kHz (the external equivalent load of the user must be higher than 12 mA.)
Common terminal mode One common terminal for every four channels
◆
The total extended distance of the extension cable of the high-speed I/O interface must be less
than 3.0 m.
◆
The duty cycle must be greater than 40% when two-phase (phase A and phase B) input mode is
adopted.
