This device supports multiple sensor types, including thermocouples and RTDs. Its high resolution guarantees accurate process monitoring. Additionally, the module features a robust screw terminal block for secure wiring. It is ideal for temperature and analog signal measurement in automation systems.

Technical Specifications

Input Characteristics

The TM3TI4D module features four dedicated analog inputs. Each channel is individually configurable. It accepts current signals from 0 to 20 mA or 4 to 20 mA. Furthermore, it handles voltage signals of 0 to 10 V and -10 to 10 V. For temperature measurement, it supports thermocouples like J, K, R, S, B, T, N, E, and C. It also supports Pt100, Pt1000, Ni100, and Ni1000 RTD probes.

Resolution and Accuracy

This analog input module delivers a high 16-bit resolution for precise signal conversion. The accuracy varies by sensor but reaches +/- 0.2% of full scale for most ranges. Specifically, for thermocouple R and S types, accuracy is +/- 0.2% above 200°C. The module maintains repeat accuracy of +/-0.5% FS. Its sampling duration is fast, ranging from 10 ms for voltage/current to 100 ms for thermocouples.

Conversion and Performance

Conversion time depends on the input type. For voltage and current, it takes 10 ms plus an additional 10 ms per channel. For temperature probes and thermocouples, it takes 100 ms plus 100 ms per channel. The LSB values are equally precise. For instance, it is 2.44 mV for the 0-10V range and 3.91 µA for the 4-20mA range. The module also features a low crosstalk level of <= 1 LSB.

Electrical Isolation and Protection

The TM3TI4D provides reliable electrical insulation. It offers isolation between the input and the supply at 1500 V AC. Additionally, it isolates the inputs from the internal logic at 500 V AC. The module withstands continuous overloads up to 13V for voltage inputs and 40mA for current inputs. Furthermore, it has a surge withstand capability of 1kV for common mode inputs.

Power Consumption

This Schneider Electric module requires a 24V DC supply. The voltage limits are between 20.4 and 28.8V. It draws a current of 45 mA at 5V DC from the bus connector. Moreover, it consumes 35 mA at 24V DC from the external supply. This low power draw helps ensure minimal impact on your control system's overall power budget.

Mechanical and Environmental Specifications

Mounting and Dimensions

The TM3TI4D is designed for easy installation. It mounts on a standard Top hat TH35-15 or TH35-7.5 rail according to IEC 60715. Alternatively, you can mount it on a plate or panel using a fixing kit. The module is compact, measuring 90mm in height and only 23.6mm in width. Its depth is 70mm, making it suitable for space-conscious control cabinets.

Environmental Conditions

This analog input module operates within a wide temperature range. For horizontal installation, the ambient temperature range is -10°C to 55°C. For vertical installation, it is -10°C to 35°C. Storage temperature can be from -25°C to 70°C. Additionally, the module can withstand relative humidity levels from 10% to 95% without condensation. Its protection rating is IP20.

Resistance and Immunity

The TM3TI4D excels in harsh industrial environments. It resists electrostatic discharge of 8kV in air and 4kV on contact. Immunity to electromagnetic fields is rated at 10 V/m from 80 MHz to 1 GHz. It also withstands fast transients at 1kV. The module is certified with CE, UKCA, RCM, EAC, and cULus, including HazLoc for hazardous locations.

Vibration and Shock

This module is built to endure mechanical stress. It has a vibration resistance of 3.5 mm at 5 to 8.4 Hz on a DIN rail. Furthermore, it withstands 3 gn of vibration from 8.4 to 150 Hz. Its shock resistance is rated at 15 gn for 11 ms. These specifications ensure reliable operation in applications with significant machinery vibration.

Installation and Wiring Guide

Mechanical Installation

First, ensure the DIN rail is securely attached to your cabinet. Next, clip the TM3TI4D module onto the rail. For a secure fit, push the bottom of the module until the latch clicks. If you are using a panel mount, attach the fixing kit first. Finally, ensure adequate clearance around the module for ventilation.

Electrical Wiring

The module uses a removable screw terminal block with a 3.81mm pitch. This design allows for easy pre-wiring. Use twisted shielded pair cables for all input circuits to reduce noise. The maximum cable length should be less than 30 meters. Ensure the external 24V DC power supply is stable and within the specified range.

Configuration

After wiring, you must configure the module in your programming software. Select the appropriate input type for each of the 4 channels. This selection is critical for accurate readings. For instance, you must choose between a Pt100 sensor or a type K thermocouple. Finally, set up the correct scale and filter parameters for your application.
