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.Specification:Number of channels: TwoSignal source: THC types J, K, T, E, R, S, B or N to BS 60584 and XK mV inputLocation of signal source: Zone 0, IIC, T4–6 hazardous area Division 1, Group A, hazardous locationInput signal range: –75 to +75mVInput 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
