The Series LTI Temperature Panel Meter can be programmed in the eld to accept a thermocouple or RTD input and display the temperature on a six-digit dual line display. The upper display will display four digits of temperature as well as °C or °F symbol. The lower display can be programmed to contain a tag. The Series LTI meters feature a NEMA 4X / IP65 front panel making them ideal for wet, dusty and dirty environments. Options include 2 or 4 relays and a 4-20 mA output. The 4-20 mA output option turns the LTI into an isolated temperature transmitter with a digital display. The LTI includes free USB based programming software to make programming a breeze.
