MTL4676-RTD temperature convert

The MTL4676-RTD converts low–level dc signals from temperature sensors mounted in a hazardous–area into 4/20mA currents. Software selectable features include linearisation for standard thermocouple types, ranging, monitoring, testing and tagging. Configuration is carried out using a personal computer. The field connections include cold–junction compensation and do not need to be ordered separately.

Input signal range:–75 to +75mV

Input signal span:3 to 150mV

Cold junction compensation:Automatic or selectable

Cold junction compensation error:≤ 1.0°C

Common mode rejection:120dB for 240V at 50Hz or 60Hz

Series mode rejection:40dB for 50Hz or 60Hz

Safety drive on sensor burnout:Upscale, downscale, or off

Output range:4 to 20mA nominal into 300Ω max. (direct or reverse)

Maximum lead resistance:300Ω

Power requirement, Vs with 20mA signal:60mA at 24V

Power dissipation within unit with 20mA signal:1.4W at 24V
