133819-01 | Bently Nevada | RTD/TC Temp I/O Module
Product No. : 133819-01
Product type : 3500/60 RTD/TC Non-Isolated I/O Module Internal
Features:
(6) Channels of Temperature Monitoring
Ttemperature Inputs: Resistance Temperature Detector (RTD) and Thermocouple (TC)
Recorder Outputs for each Channel (3500/61)
RTD/TC Non-Isolated or TC Isolated Versions
The GE / Bently Nevada 3500/60 and 3500/61 Series Temperature Monitors 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.
