Schneider TM3DI32K 24V DC Input Module

Schneider TM3DI32K Discrete Input Module

Product Introduction

The Schneider Electric TM3DI32K brings 32 discrete inputs to your control system. Each channel accepts 24V DC signals with sink or source wiring. This module fits perfectly with Modicon M221, M241, M251, and M262 controllers.

Additionally, the TM3DI32K uses an HE10 connector for fast field wiring. Its input impedance sits at 4.4 kOhm, while each channel draws only 5 mA. You can connect unshielded cables up to 30 meters without trouble.

For reliable detection, the on-state voltage ranges from 15 to 28.8V DC. The off-state voltage stays below 5V DC. Consequently, the module meets IEC 61131-2 Type 1 standards.

Technical Specifications of TM3DI32K

Input characteristics are critical for automation. The TM3DI32K guarantees an on-state current above 2.5 mA. Its off-state current remains under 1 mA. Response time equals 4 ms for both turn-on and turn-off.

Moreover, local signalling includes one green LED per channel. This helps you monitor each input instantly. The module draws 65 mA at 5V DC from the bus when on. When off, it consumes only 5 mA at 5V DC.

Insulation between inputs and internal logic withstands 500V AC. However, inputs are not isolated from each other. Therefore, group your wiring carefully for mixed voltage zones.

Mechanical & Environmental Data

The TM3DI32K measures 33.5 mm wide, 90 mm high, and 81.3 mm deep. It weighs just 0.1 kg. Mounting options include TH35-7.5 or TH35-15 rails, or a plate using a fixing kit.

Operating temperature ranges from -10°C to 55°C horizontally, or -10°C to 35°C vertically. Storage temperature goes from -25°C to 70°C. Relative humidity can reach 95% without condensation.

Furthermore, vibration resistance reaches 3.5 mm at 5–8.4 Hz, then 3g up to 150 Hz. Shock resistance stands at 15g for 11 ms. The IP20 rating applies only when the protective cover is in place.

Installation Guidelines for TM3DI32K

First, turn off all power before handling the TM3DI32K. Clip it onto a DIN rail or mount it on a panel. Next, connect the HE10 cable to your field devices. Ensure each input receives 24V DC nominal.

For best results, keep unshielded cables shorter than 30 meters. Use shielded cable if you run near inverters or heavy contactors. Then, configure your Modicon controller to recognise the Schneider Electric TM3DI32K in the I/O map.

Finally, test each input with a signal source. Watch the green LEDs confirm the correct state. Remember to leave space for ventilation, especially in vertical mounting.

Frequently Asked Questions (FAQ)

1. Can the TM3DI32K work with Modicon M221?
Yes, the TM3DI32K is fully compatible with M221, M241, M251, and M262 controllers.

2. What happens if I mix sink and source wiring on the same module?
You can use sink or source logic per module, but not per channel. Pick one wiring method for all 32 inputs.

3. How far can my sensors be from the TM3DI32K?
You can run unshielded cable up to 30 meters. For longer runs, use shielded cable and consider signal degradation.

4. Why do all green LEDs stay off even with voltage applied?
Check the common connection first. The TM3DI32K needs a proper return path. Also verify voltage is above 15V DC.

5. Does the module support hot swapping?
No, do not remove or insert the TM3DI32K while the system is powered. Always turn off the controller bus power first.
