Schneider TM3DI32K Overview: Specs & Applications
Schneider TM3DI32K Technical Overview
The Schneider TM3DI32K discrete input module from the Modicon TM3 family delivers 32 digital inputs at 24 V DC with sink or source logic. It integrates directly with Modicon M221, M241, M251, and M262 controllers, providing a consistent interface for field devices.
Electrical Specifications
Each input channel operates at 5 mA typical current. Voltage state 1 ranges from 15 to 28.8 V, while state 0 is 0 to 5 V. Input impedance is 4.4 kOhm, and response time is 4 ms for both turn-on and turn-off. The module consumes 65 mA at 5 V DC via the bus connector when inputs are active, and 5 mA when off. A green LED per channel indicates input status.
Connection and Mounting Details
A HE-10 connector provides electrical connection for all 32 inputs. Unshielded cable runs up to 30 meters are supported. Mount the module on a TH35-15 or TH35-7.5 DIN rail or on a panel with a fixing kit. Dimensions are 90 x 33.5 x 81.3 mm, weight 0.1 kg.
Environmental and Certification Highlights
The TM3DI32K holds certifications including CULus, CE, UKCA, RCM, and EAC, complying with EN/IEC 61131-2 and 61010-2-201. It withstands electrostatic discharge of 8 kV in air and 4 kV on contact. Electromagnetic field resistance is 10 V/m from 80 MHz to 1 GHz. Surge withstand is 1 kV common mode for DC I/O. The module also meets marine specifications from LR, ABS, DNV, and GL. Insulation between input and internal logic is 500 V AC. Operating temperature is -10 to 55°C horizontally or -10 to 35°C vertically, with 95% humidity non-condensing. IP20 protection and pollution degree 2 apply. Vibration resistance is 3.5 mm at 5–8.4 Hz on DIN rail, and shock resistance is 15 gn for 11 ms.
With comprehensive protection and broad compatibility, the Schneider TM3DI32K offers a reliable digital input solution for automation engineers.
