It gives you two analog inputs and one analog output on a slim 23.5 mm wide package — fits into the M238 rack without crowding adjacent modules. Inputs accept 3-wire Pt100 probes, thermocouples J/K/T, 0-10 V, or 4-20 mA. The single output can be configured as 4-20 mA or 0-10 V. That covers most analog signals a small machine cell throws at it. Conversion time runs 20 ms plus one controller cycle for most inputs, 60 ms for thermocouples. Total error across all ranges is ±1% of full scale; repeat accuracy holds ±0.5% FS. Tight enough for temperature monitoring or basic process control.","metaTitle":"TM2ALM3LT Analog I/O Module, 2AI/1AO, Obsolete","metaDescription":"TM2ALM3LT obsolete analog module for Modicon M238. 2 inputs, 1 output, 24 VDC.
