Description

Description
The 3500/62 Process Variable Monitor is a 6-channel monitor
for processing machine critical parameters that merit
continuous monitoring, such as pressures, flows,
temperatures, and levels. The monitor accepts +4 to +20 mA
current inputs or any proportional voltage inputs between -10
Vdc and +10 Vdc. It conditions these signals and compares
the conditioned signals to user-programmable alarm
setpoints.
The 3500/62 monitor:
l Continuously compares monitored parameters
against configured alarm setpoints to drive alarms for
machinery protection.
l Provides essential machine information for both
operations and maintenance personnel.
You can program the 3500/62 using the 3500 Rack
Configuration Software to perform either current or voltage
measurements. The 3500/62 offers I/O modules for three
signal input scenarios: +/-10 Volts DC, isolated 4-20 mA, or 4-
20 mA with Intrinsically Safe zener barriers. The Internal Barrier
I/O provides external power input terminals to provide
intrinsically safe power to the 4-20 mA transducers
When used in a Triple Modular Redundant (TMR)
configuration, you must install Process Variable Monitors
adjacent to each other in groups of three. When used in this
configuration, the monitor employs two types of voting to
ensure accurate operation and to avoid loss of machinery
protection due to single-point failures.
