Overview

The 3500/60 & 3500/61 modules are designed for temperature monitoring and support both Resistance Temperature Detector (RTD) and Thermocouple (TC) temperature inputs. These modules condition the incoming signals and compare them against user-programmable alarm setpoints.

The main difference between the two models is:

• The 3500/60 provides temperature monitoring for up to six channels without recorder outputs.
• The 3500/61 provides identical functionality to the 3500/60, with the addition of recorder outputs for each of its six channels.
