4.5.1 Basic Specifications
4.5 Specifications
Number of inputs Voltage or no-voltage contact pulse input × 1 channel
Clamp-type current pulse input × 1CH (Detected using externally connected 9766
CLAMP ON SENSOR.)

Simultaneous detection on 2 channels is also possible.
Measurement range Voltage/no-voltage contact pulse up to 4 kHz (Input terminals set by commands)
• Lo range, no-voltage contact terminals
Voltage pulse
A pulse is counted when the voltage level changes from L to H.
L: +0.0 to +0.2 V
H: +1.5 to +45 V
(Logic in the range from +0.2 to +1.5 V is indefinite.)
No-voltage contact pulse:
A pulse is counted when the circuit between the terminals changes from a short circuit
to an open circuit.
Contact Detection Level: short circuit of 500
Ω
or less
open circuit of 500 k
Ω
or more
• High range, terminals
Voltage pulse
A pulse is counted when the voltage level changes from L to H.
L: +0.0 to +4.0 V
H: +10.0 to +45 V
(Logic in the range from +4.0 to +10.0V is indefinite.)
• Current pulse
Detected current range 10 to 20 mAp-p
