V/I Converter
( JGSM-16-== )
＊2
Converts DC voltage input signal to current
signal of 4 to 20 mA which can be
connected to instrument. Insertion of snap-
in module can determine input signals such
as frequency or tach-gen.

Signal
Selector A
(JGSM-13)
Consists of power supply circuit and two
relay circuits.
Used as a selector circuit of control signals.
Signal
Selector B
(JGSM-14)
Contains three relay circuits. Used as a
selector circuit of control signals. Power
supply from model JGSM-13.
Comparator
( JGSM-15-== )
＊2
Compares DC voltage, current, AC tach-
gen, frequency, or reference signals with
two preset levels. It drived relays and
output contact signal (1NO, NC contact.)
