Bently Nevada 3500/61 modules provide

Description

The 3500/60 & 61 modules provide six channels oftemperature monitoring and accept both ResistanceTemperature Detector (RTD) and Thermocouple (TC)temperature inputs.  The modules condition these inputs andcompare them against user-programmable alarm setpoints. The 3500/60 and 3500/61 provide identical functionalityexcept that the 3500/61 provides recorder outputs for each ofits six channels while the 3500/60 does not.The user programs the modules to perform either RTD or TCtemperature measurements using the 3500 RackConfiguration Software.  Different I/O modules are available inRTD/TC non-isolated or TC isolated versions.  The user canconfigure the RTD/TC non-isolated version to accept either TCor RTD, or a mixture of TC and RTD inputs. The TC isolatedversion provides 250 Vdc of channel-to-channel isolation toprotect against external interference.When used in a Triple Modular Redundant (TMR)configuration, temperature monitors must be installedadjacent to each other in groups of three. When used in thisconfiguration, the system employs two types of voting toensure accurate operation and to avoid single-point failures.
