The SR630 monitors 16 independent input channels, each separately configurable for 7 different types of thermocouples or as a DC microvoltmeter. The front panel reading for each input can be displayed in °Fahrenheit, °Celsius or °Kelvin, as well as mVolts and Volts. All with up to 5 digits of resolution. Measurements are made 12 times per second and digital filtering is used to reduce noise. Up to 16 channels may be sequentially scanned with dwell times of 0.5 second to 9,999 seconds between channels. Programmable audible alarm limits for each channel alert the user to excess temperature deviations. The back panel relay output is also closed with the alarm to provide shut-down capability. The isolated differential inputs have a 250 Volt break-down level, allowing the SR630 to tackle difficult applications such as temperature profiling of electrically live equipment.
