
(9)“WIDTH”Select Switch
Selects output pulse width.
“1:1” …… Pulses with 1:1 ON/OFF ratio
“0.25”…… Pulses 0.25ms±10% wide (2000Hz or lower)
“1” …… Pulses 1ms±10% wide (500Hz or lower)
“50” …… Pulses 50ms±10% wide (10Hz or lower)
(10)“OUTPUT”Select Switch
Selects the generator type for output pulses.
“OPTO” …… A simulated output of OPTO 01/02 generator circuit
“PG20” …… A simulated output of PG20M generator circuit
Coupling conditions are 30V dc and 20mA max. because it provides an open
collector output of transistors rather than a relay counterpart.
“PG30” …… A simulated output of PG30 generator circuit
“P.A.” …… A simulated output of PA04/05/45 or PG60A (E) generator circuit
“PG30S” …… A simulated output of PG30S generator circuit
“O.C.” …… A simulated output of FLOWPET NX or PG60A (E) generator circuit
“VOLT” …… A voltage pulse output from 8V internal power source
“PA11” …… A simulated output of PA11 generator circuit

Figures in the box □ show the resistance values. (Examples: 100k→100kΩ, k5→.5kΩ)
Output frequency should be chosen within the conditions in brackets ( ) when you select a
particular fixed pulse width.
The ON/OFF ratio is 1/1 when the frequency is at maximum of the figure in the brackets ( ); the
OFF width becomes smaller progressively as the frequency exceeds that figure; at frequencies
twice that figure, or greater, pulses will overlap and no output will be produced: the "OUTPUT
COUNTER" will fail to count.
CAUTION:
