Description
This product is part of the Modicon TM3 range, an offer of expansion I/O modules for Modicon M221, M241, M251 and M262. The analogue input module provides 8 inputs with 11bit + sign and 12bit resolution. It is an input module with a rated supply voltage of 24V DC and a current consumption of 35mA at 5V DC via bus connector no load, 45mA at 5V DC via bus connector full load, 30mA at 24V DC via external supply. This product is capable of controlling variable speed drives or any device equipped with a current or voltage input. There is an insulation between input and supply at 1500V AC, input and internal logic at 500V AC. It is furnished with removable screw terminal for electrical connection with 3.18mm pitch adjustment for inputs and supply. It is an IP20 rated product. Its dimensions are 23.6mm (Width) x 70mm (Depth) x 90mm (Height). It weighs 0.11kg. This product is certified by CE. It meets EN/IEC 61131-2 and EN/IEC 61010-2-201 standards. This module is compatible with Modicon M262, Modicon M241, Modicon M251 and Modicon M221 logic controller. It supports top hat type TH35-15, top hat type TH35-7.5 rail conforming to IEC 60715 and plate or panel with fixing kit mount. Modicon TM3 expansion modules have been designed with a simple interlocking assembly mechanism. A bus expansion connector is used to distribute data and the power supply when assembling the Modicon TM3 modules with logic controllers. Boost the performance of your controller with the Modicon TM3 I/O system specially designed for the Modicon M221, M241 and M251 logic controllers.
Features
- This Schneider Electric Modicon TM3 expansion module delivers 8 high-resolution analog inputs in a compact, snap-on form factor, allowing you to instantly scale up your automated system. It connects directly via a rugged, built-in bus extension connector to Modicon M221, M241, M251, and M262 logic controllers, completely eliminating the need for complex field bus configurations or external communications hardware.
- Designed for maximum field flexibility, each of the 8 inputs can be individually configured via software to accept standard industrial signals including 0-10 V, -10 to +10 V voltage loops, and 0-20 mA or 4-20 mA current loops. This wide signal compatibility allows process control engineers to mix and match pressure transmitters, flow meters, and level sensors on a single module, drastically reducing spare parts inventory and hardware costs.
- Featuring a high-performance 11-bit plus sign (or 12-bit) analog-to-digital converter, this module converts incoming process signals into precise digital data with a resolution of up to 2.44 mV for voltage and 4.88 µA for current loops. Combined with a lightning-fast hardware conversion time of just 1 ms per channel, it delivers the real-time, high-accuracy data required for demanding PID loops and sensitive process regulation.
- Engineered to withstand harsh, electrically noisy factory environments, this module features robust photovoltaic and galvanic isolation rated up to 1500 V AC between the input channels and internal logic, and 500 V AC between inputs and the power supply. This exceptional shielding prevents ground loops and eliminates high-frequency electromagnetic interference (EMI), ensuring stable, jitter-free sensor readings even when routed next to high-power variable speed drives (VSDs).
- Equipped with standard, high-density removable screw terminal blocks, this module simplifies pre-wiring and accelerates field replacements since the entire wiring harness can be unplugged without disconnecting individual sensor leads. Bright, front-facing LED status indicators provide immediate, real-time diagnostic visibility for channel health, power supply presence, and bus communication errors, allowing maintenance teams to troubleshoot issues in seconds.
- Fully certified to strict CSA, CE, UKCA, and EAC industrial automation standards, this authentic Modicon component guarantees complete safety and compliance across Canadian and international processing plants. It also holds Green Premium status with strict adherence to RoHS and REACh standards, assuring your plant upgrades align perfectly with modern corporate environmental sustainability mandates.
