SPECIFICATIONS
Notes: 1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 °C
+68 °F
.
2) A typical sample applied with a supply voltage of 24 V, a distance of 100 mm
3.937 in
from the front surface of the air flow outlet and a pressure of 0.25
MPa. (Measured on a sample left in the atmosphere at a relative humidity of 65 % RH or less for 24 hours or more.)
3) A typical sample applied with a supply voltage of 24 V, a distance of 300 mm
11.811 in
from the front surface of the air flow outlet and a pressure of 0.25 MPa.
4) Dried clean air is the air passing through air dryer (dew point –20 °C
–4 °F
approx.) and air filter (mesh size 0.01 μm
0.0004 mil
approx.)
5) ‘‘DSC’’ is an abbreviated name of ‘‘DISCHARGE’’.
6) Discharge halts when lights up.

Output
Check (CHECK)
Error (ERROR)
Discharge (DSC) (Note 5)
NPN open-collector transistor
• Maximum sink current: 50 mA
• Applied voltage: 30 V DC or less (between output and 0 V)
• Residual voltage: 1 V or less (at 50 mA sink current)
Output operation
Check output (CHECK): ON when the discharge needle is dirty or worn, OFF when operation is normal
Error output (ERROR): OFF when abnormal discharge is detected, ON when operation is normal
Discharge output (DSC) (Note 5): ON when discharging, OFF when discharge halts
Short-circuit protection
Incorporated
Discharge halt input (DSC OFF) (Note 5)
Short-circuit to 0 V: Discharge halt, Open: Discharge allowed (operation start)
Reset input (RESET)
In the state that operation is stopped due to an error detection, open 0 V of the power supply from short-circuit state to cancel ERROR
