GE / Bently Nevada 3500/60和3500/61系列温度监控模块提供六个温度监控通道,并接受电阻温度检测器(RTD)和热电偶(TC)温度输入。这些模块调节这些输入,并将其与用户可编程的报警设定值进行比较。3500/60和3500/61提供相同的功能,只是3500/61为其六个通道中的每一个通道提供记录器输出,而3500/60不提供。

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.
