(2) External Input/Output Signals
･
Pins 1, 2 :
Terminals to accept power to drive the valve
(
100VAC or 24VDC
)
.
･
Pin 3 :
Common terminal for valve output.
･
Pins 4, 5 :
Squeeze output terminals for valves
(
Input voltage to Pin 1, 2 is
output
)
. 4 = Valve 1, 5 = Valve 2
Do not connect a valve of more than 0.5A. When using a valve of
more than 0.5A, operate an auxiliary relay with this VALVE output
and supply a voltage with the relay contact to the valve.
･
Pin 6 :
0V terminal for
IS-120B
only. Do NOT use for another purpose.
･
Pin 7 :
24V terminal for
IS-120B
only. Do NOT use for another purpose.
･
Pin 8 :
Control power input terminal for external signals. Connect Pin 6
or 7 to this terminal depending on input signal circuit.
･
Pin 9 :
Common terminal for external signals. Connect pin 6 or 7 to this
terminal according to input signal circuit.
･
Pin 10 :
Common terminal for schedule signal input.
･
Pins 11-14 :
Schedule input terminals. Generally used for schedule selection
signal input and start signal input.
11 = Schedule 1, 12 = Schedule 2, 13 = Schedule 4,
14 = Schedule 8
･
Pin 15 :
Common terminal for input.
