MTL 5500 Intrinsically Safe Isolators  MTL5576-THC

MTL4576-THC – MTL5576-THC TEMPERATURE CONVERTER mV/THC input, 2-channel
The MTLx576–THC converts low–level dc signals from temperature sensors mounted in a hazardous–area into 4/20mA currents for driving safe–-area loads. Software selectable features include linearisation for standard thermocouple types, ranging, monitoring, testing and tagging. Configuration is carried out using a personal computer. The hazardous–area connections include cold–junction compensation and do not need to be ordered separately.
