Current Switch Normally Open
CR9300 Series
The
CR9300
Series is a low cost, self powered, fixed set-point Current Switch
designed for applications that require an on-off indication of current flow.
Current levels above the guaranteed full-on level will turn the output to full on.
The Current Switch is recommended only for applications where the continuous
operating current 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 is available with a NPN or PNP output transistor for switching DC and a
SCR output for switching AC. Connections can be made directly to items such as
a PLC or electromechanical relay. Note that connections made directly to an in-
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)
ductive device such as an electromechanical relay will require a customer sup-
plied clamping diode for DC operation or a snubber network for AC operation.
