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:
Continuously compares monitored parameters against configured alarm setpoints to drive alarms for machinery protection.

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.

Triple Modular Redundant (TMR) Units are no longer available for purchase.
