Bently Nevada 163179-02 3500/61 Temperature Monitor (with recorders)

Description

The Bently Nevada 163179-02 3500/61 Temperature Monitor provides six channels of temperature monitoring and accepts both Resistance Temperature Detector (RTD) and Thermocouple (TC) inputs. The module conditions these inputs and compares them against user-programmable alarm setpoints. Unlike the 3500/60, the 3500/61 includes recorder outputs for each of its six channels.

The user can configure the module for 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, with the TC isolated version offering 250 Vdc of channel-to-channel isolation.
