ADAM-5510/P31
3-3
Chapter 3
3-way isolation and watchdog timer
Electrical noise can enter a system in many different ways. It may enter
through an I/O module, a power supply connection or the communica-
tion ground connection. The ADAM-5510/P31 system provides
isolation for I/O modules (3000 V
DC
), communication connections (2500
V
DC
), and communication power connections (3000 V
DC
). The 3-way
isolation design prevents ground loops and reduces the effect of
electrical noise on the system. It also offers better surge protection to
prevent dangerous voltages or spikes from harming your system. The
system also has a watchdog timer to monitor the microprocessor. The
watchdog timer automatically resets the microprocessor in the
ADAM-5510/P31 system if the system fails.
