Schneider TM3AM6 Modicon TM3 Analog I/O Module 4 Inputs 2 Outputs

Schneider Electric Modicon TM3AM6 is an analog I/O module with 4 inputs and 2 outputs. Inputs configurable for voltage (±10 V, 0‑10 V) or current (0‑20 mA, 4‑20 mA). Outputs configurable for voltage (0‑10 V) or current (0‑20 mA, 4‑20 mA). Screw terminal block. Part of the TM3 expansion family for Modicon M221, M241, M251, and M262 controllers.
