Digital output
The alarm output single of this unit is a digital signal. Connect these terminals as required, with reference to the
table below.
Terminal
name
Signal name
Output content ： factory setting
DO1 Digital output 1
When switching the PQ number, it becomes ON if the pressure
command, flow rate command has reached the goal
DO2 Digital output 2 No output (Do not connect)
OCOM
Digital output COM
Both positive and negative signals are acceptable

External power
supply (DC24V)
CAUTION
●
As the external power supply, prepare a 24 VDC ±1 V, 0.5 A power supply. Power cannot be supplied from
this controller to external equipment.
● The maximum output current of an output circuit is 50mA (resistance load). If you attempt to drive load
higher than the allowable current, the circuit may be damaged. Pay attention to the maximum allowable
current.
● To drive induction load, take surge preventive measures.

Contact output
The contact output signal for alarms. Connect these terminals as required, with reference to the table below.

Alarm output a point
Continuity with “Common” exists when the pressure switch is normal.
AL_B
Alarm output b point
Continuity with “Common” exists when the pressure switch works or
alarm occurs.

CAUTION
●
The contact output switching capacity is 30 VDC/0.5 A (resistance load). If you attempt to drive load higher
than the allowable current, the contact may be damaged. Pay attention to the maximum allowable current.
●
The minimum allowable load of the contact output is 10 mVDC/10 μ A. However, it is an approximate lower
limit that enables the contact to be opened/closed under minute load. This value varies depending on switching
frequency and environmental conditions. We recommend you to check the minimum allowable load in actual
conditions.
●
To drive induction load, take surge preventive measures.
