The CNL70 is a programmable digital signal conditioner powered by a 4–20 mA current loop (
) with an LCD display, designed for measuring temperature sensors (thermocouples and PT100s) as well as process signals (mV, mA). Optionally, it can include Hart protocol communication and meet the SIL2 safety integrity level (
) in accordance with IEC 61508.
