Description
Provides the output for remote
DeviceNet indicators and is
connected to the emitter of an
opto-coupler. You must limit
current draw through this pin to
45 mA or less.
Note: Defined by DeviceNet
Specification, Release 2.0
(see the Open DeviceNet
Vendor Association web
site at www.ODVA.org)
Enables the internal AC power
contactor with an external closure
between pins 11 and 12 (provided
front panel Standby switch is
closed and RF output cover is on).
External series resistance must be
15 Ω or less. This pin is tied to
+15 V by a resettable fuse.
Note: When this loop is
interrupted, the unit
disables the output by
opening the main contactor
inside the supply. Once the
interlock is reestablished,
the main contactor will
close, but the output will
not come on until the RF
POWER ENABLE line
(pin 4) is cycled.
