Allen-Bradley 1734-IT2I is a 24V DC POINT I/O two‑channel thermocouple input module that equips a POINT I/O rack with isolated thermocouple measurements. It provides two differential, isolated inputs with an input range of ±75 mV and a 15‑bit plus sign resolution (2.5 mV per count); cold junction compensation can be enabled or disabled via a module setting. The module draws power from the POINTBus (maximum 175 mA at 5V) and requires no external supply; its isolation between I/O and the backplane is 50V continuous, and its external dimensions are approximately 56.6 x 12.1 x 77.5 mm (2.23 x 0.48 x 3.05 in).
