Current Switch - Normally Closed
CR9400 Series
The CR9400 Series is a low cost, self powered, fixed set-point Current
Switch designed for applications that require an on-off indication of
current flow.
The normal state of the switch is On when the current level is zero. Cur-
rent levels above the guaranteed full-off level will turn the output to Off.
The Current Switch is recommended only for applications where the
continuous operating level is above the rated full on level of 350 mA.
Operation below this point will not drive the output device full-on and
derate the output ratings.
The unit available with a SCR output for switching AC. Connections can
be made directly to items such as a PLC or electro-mechanical relay.
DC SWITCHING (-NPN or -PNP)
Vce (full off): 30 VDC max.
Isink (full on): 120 mADC max.@ rated full-on
Vce (reverse polarity voltage): 1.2 VDC @
100 mADC
Vce (full on): 1.5 VDC @ 120 mADC Isink
Off state leakage current: 5ua @ 30 VDC
(typical)
Note that connections made directly to an inductive device such as an
electro-mechanical relay will require a customer supplied clamping
diode for DC operation or a snubber network for AC operation.
