The Model I and Model III of this
series provide 1 6-pin 5.08mm pitch
input DC terminal. The power supply
occupies 4 pins and provides 2
independent power supply systems, PWR1 and PWR2. When
one power supply fails, it can switch to another one
automatically and immediately to ensure device
’s normal
power supply. Power supply input of Model I: 48VDC, power
supply range of Model III: 48VDC (12~48VDC).
【
Relay Connection
】
Relay terminal is a set of normally open contacts of device
’s
alarm relay. It is in open circuit status when it has no alarm,
close circuit when it has any alarm. For example: when
powered off, it
’s in close circuit and sending out alarm. This
switch supports 1 relay alarm information output, output power
supply alarm or network anomaly alarm. It can attach external
warning light, alarm buzzer or other switch states acquisition
device to warn operators in time when there has an alarm.
【
Flange Interface Connection
】
This device provides Bypass function. As shown below, A2
and B2 ends that on the left side represent internal terminal
blocks of flange interface, A1 and B1 ends that on the right
side of dotted line represent external terminal blocks of flange
interface.
