The Bently Nevada Orbit 60R/INP static input module provides six transducer connections per module. This module conditions and digitizes the inputs at a rate that encompasses the signal content and allows for removal of typical noise sources.
The three modules are:
RTD/TC Temperature Input Module (RTD)
Isolated TC Temperature Input Module (ITC)
Isolated Process Variable / Discrete Input Module (PVD)
The primary purposes of these modules are to continuously process input from connected inputs to be compared against configured alarm setpoints to drive alarms for machinery protection and provide discrete inputs for essential operational commands, such as trip multiply for machine start-up and alarm inhibit.
RTD/TC Temperature Input Module (RTD)
Each channel of the RTD is individually configurable for sensor type and range. The thermocouple configured channels provide cold junction compensation for type J, K, E, or T thermocouple. The RTD/TC inputs are referenced to the internal system ground and for this reason should only be connected to transducers that are isolated at the sensing end.
Isolated TC Input Module (ITC)
Each channel of the ITC input module is individually configurable for sensor type and range. The thermocouple configured channels provide cold junction compensation for type J, K, E, or T thermocouples.
Isolated Process Variable / Discrete Input Module (PVD)
The PVD processes machine critical parameters such as pressure, flow, temperature, and levels that merit continuous monitoring. The module conditions and digitizes the signals so that the result can be compared with user-programmable alarm setpoints. The user can program the PVD module using the configuration software to perform current, voltage or discrete input measurements. The monitor accepts 4 to 20mA current inputs or any proportional voltage inputs between -10Vdc and +10Vdc, in addition to monitoring “dry” or “wet” contacts which can be a sensor, switch, or relay.
