Schneider Electric TM3TI4 Modicon TM3 Analog Input Module – 4 Channels, 16-bit, Voltage/Current/TC/RTD, Screw Terminal

Descripción del Producto

The Schneider Electric TM3TI4 is a 4-channel analog input expansion module from the Modicon TM3 range, designed for use with Modicon M221, M241, M251, and M262 logic controllers. It accepts voltage (0–10 V, –10…+10 V), current (0–20 mA, 4–20 mA), isolated thermocouple (K, J, R, S, B, E, T, N, C), and 3-wire RTD (PT100, PT1000, NI100, NI1000) signals with 16-bit resolution. The module features a removable screw terminal block, a 24 VDC power supply with a 20.4–28.8 VDC operating range, and a self-scan operating mode using a sigma-delta ADC. Typical applications include temperature monitoring, process signal acquisition, and machine control in industrial automation and infrastructure systems.

Características estándar

• 4 Universal Input Channels: Supports voltage, current, thermocouple, and 3-wire RTD signals on a single module, reducing the number of different I/O modules required in a panel.
• 16-bit High Resolution: Provides 16-bit resolution or 15 bits plus sign (65,536 points) for precise measurement of analog process signals.
• Wide Signal Range Coverage: Accepts 0–10 V and –10…+10 V voltage inputs, 0–20 mA and 4–20 mA current inputs, 9 thermocouple types (K, J, R, S, B, E, T, N, C), and 4 RTD types (PT100, PT1000, NI100, NI1000).
• Removable Screw Terminal Block: Detachable screw terminal block simplifies wiring, maintenance, and module replacement without disturbing field wiring.
• High Accuracy Sigma-Delta ADC: Delivers ±0.2% of full-scale accuracy at 25 °C for voltage, current, and most temperature inputs, with cold-junction accuracy of ±4.0 °C for thermocouples.
• Software-Configurable Sampling: Sample duration time is configurable at 10 ms or 100 ms per enabled channel, allowing optimization between speed and noise rejection.
• Compact DIN Rail Mounting: Module width of 23.5 mm and weight of 110 g, with status LEDs (PWR, RUN, ERR) for quick diagnostics and a maximum cable length of 30 m for shielded twisted-pair wiring.
