■External I/O signal
External input
No-voltage contact input or plus common/minus common DC-input
(Selectable by specifying at time of order)
Number of circuits 3
Signals DZ, HOLD, H.RESET
<No-voltage contact input (NVI)>
Relays, switches, and transistors can be connected.
Signals are input by the short-circuit and open-circuit between input terminals and the common
terminal.
Use a sink type when connecting transistors.
Internal power supply voltage DC12V
Short circuit flow Approx. 4mA
<DC-input (DCI)>
Relays, switches, and transistors can be connected.
Signals are input by applying voltage between the input terminals and the common terminal.
Use a sink type for plus common and a source type for minus common when connecting
transistors.
Rated voltage DC27.6Vmax
ON condition DC9V or more (load current at DC24V = approx. 10mA)
OFF condition DC3V or less
External output
PhotoMOS relay output commonly for sink/source
Number of circuits 5
Signals HI, OK, LO, output selection 1, output selection 2
(Output selection can be selected by setting HH limit, LL limit,
overload, RUN, hold zero, near zero, and DZ response.)
Rated voltage DC30Vmax
Rated current 100mAmax
Operation time Approx. 1mSec.
