3500/60 and 3500/61 Temperature
Modules
Datasheet
Bently Nevada Machinery Condition Monitoring
Description
The 3500/60 & 61 modules provide six channels of
temperature monitoring and accept both Resistance
Temperature Detector (RTD) and Thermocouple (TC)
temperature inputs. The modules condition these inputs and
compare them against user-programmable alarm setpoints.
The 3500/60 and 3500/61 provide identical functionality
except that the 3500/61 provides recorder outputs for each of
its six channels while the 3500/60 does not.
The user programs the modules to perform either RTD or TC
temperature measurements using the 3500 Rack
Configuration Software. Different I/O modules are available in
RTD/TC non-isolated or TC isolated versions. The user can
configure the RTD/TC non-isolated version to accept either TC
or RTD, or a mixture of TC and RTD inputs. The TC isolated
version provides 250 Vdc of channel-to-channel isolation to
protect against external interference.
When used in a Triple Modular Redundant (TMR)
configuration, temperature monitors must be installed
adjacent to each other in groups of three. When used in this
configuration, the system employs two types of voting to
ensure accurate operation and to avoid single-point failures.

When using any of the isolated
thermocouple I/O modules (-03 or -04
I/O ordering option) with Type E
thermocouples, the available full-scale
range will be reduced if the 3500
system is operated in an ambient
temperature above +35C. The reduced
range will be -60C to +1000C (-76F to
+1832F). Rack configuration software
will allow the user to configure a
channel down to -100C but the system
will not function properly in this
scenario and therefore should not be
configured to operate with these
settings.
