The TM5SAI2H is a 2-channel analog input module for the Modicon TM5 system, accepting ±10 V and 0...20 mA signals with a 15-bit + sign resolution for voltage and 15-bit resolution for current. It samples both channels at 50 µs, making it suited for applications requiring fast measurement updates such as closed-loop control or high-speed monitoring. Power dissipation is 1.21 W, and the module is certified to CSA C22.2 No 142, IEC 61131-2, and UL 508.
Integration into a TM5 panel
The module is 12.5 mm wide, enabling dense placement on a DIN rail. Supply is drawn internally from the TM5 bus; no separate power wiring needed. The module reports its status via four LEDs (green for bus power, red for fault, and two green per channel for input activity). Operate within 0–55 °C horizontal or 0–50 °C vertical mounting; no derating required in the horizontal orientation up to 55 °C. Vibration resistance is 1 gn on DIN rail (8.4–150 Hz) and shock tested to 15 gn for 11 ms, so it holds up in machine-mounted cabinets.
If you are holding a legacy design using the TM5SAI2L, the TM5SAI2H is a drop-in upgrade at the same form factor and pinout—no panel changes, just higher performance. Confirm the faster sampling and 15-bit resolution are acceptable in your control loop before swapping.
