A The standard power cable is 3 m, but part numbers are available for lengths of 1, 3, 5, 6, 7, 8, and 10 m.
-
A Yes, it is possible. Insert the regulator body and the hexagon panel nut into the panel mounting hole (ø10.5 mm for IR1000 series regulators and ø12.5 mm for IR2000/3000 series regulators) and retighten the shaft of the pressure adjustment knob.
For new IR-A series regulators, select option “H” (With hexagon panel nut (for panel mount)).
(e.g., IR1000-01H-A) The hexagon panel nut is shipped together with the product but does not come assembled.
-
A IR series precision regulators constantly release air into the atmosphere through the bleed hole for precise adjustment.
This amount should not exceed 4.4 L/min (ANR) for IR1000/2000 series regulators and 11.5 L/min (ANR) for IR3000 series regulators.
For new IR1000-A/2000-A/3000-A series regulators, 1 L/min (ANR) is the max. amount.
Check to confirm whether the leakage is actually bleed air before taking any further steps.
Note) Refer to the “Specifications” section of the catalog for bleed measurement conditions.

A IR series precision regulators adopt a mechanism called a nozzle flapper.
The nozzle flapper controls the back pressure in the pilot chamber by opening and closing the nozzle on the outlet side against the compressed air flowing into the pilot chamber for operating the main valve. It is used for pressure setting.
In this way, the compressed air supplied to the product is constantly flowing into the pilot room in this mechanism, so air is continuously released to the outside even when the pressure at the outlet is not set. This released air is called bleed, and the majority of the air consumption listed in the catalog is bleed air consumption.
Note that bleed is a phenomenon associated with the nozzle flapper, which is separate from the relief action (action to depressurize when the set pressure rises too much).
Note 1) Be sure to use a mist separator in addition to the filters on the inlet side of IR1000/2000/3000 series regulators.
Note 2) Use a mist separator in addition to the filters on the inlet side of new IR1000-A/2000-A/3000-A series regulators if needed.

A If you order the gauge nut assembly, an Rc1/8 fitting can be mounted.
-
A Their usage depends on the load.
The 2-wire type has a large leakage current, and there are cases where the switch OFF state cannot be recognized when used in combination with a PLC.
The 3-wire type has separate power supply and signal lines, and NPN or PNP output must be selected according to the input specifications.
Leakage current:
3-wire type: 100 μA or less for 24 VDC Ex.) D-M9N
2-wire type: 0.8 mA or less for 24 VDC Ex.) D-M9B(W)
How do I use 2-wire and 3-wire solid state auto switches?
