TM3AQ4 Schneider Electric Modicon TM3 Analog Output Module
The TM3AQ4 is a 4-channel analog output module from the Schneider Electric Modicon TM3 range. It delivers 12-bit voltage or current outputs. Each channel is software configurable, so one card covers 0-10 V, ±10 V, 0-20 mA, and 4-20 mA loops. Isolation sits at 1500 V AC between output and supply. The module draws 50 mA at 5 V DC and 80 mA at 24 V DC under full load. It fits Modicon M221, M241, M251, and M262 controllers. A removable 5.08 mm screw terminal block speeds up wiring. The compact 90 × 23.6 × 70 mm housing saves panel space. This module suits machine builders who need mixed signal types on one platform.

Oiltech Controls’s Insight
- The TM3AQ4 solves a common panel problem: mixed actuator loops on one card.
- You set voltage or current per channel in software, so no hardware jumpers are needed.
- This cuts spare part count and simplifies stock for maintenance teams.
- The 12-bit resolution fits valve positioners, VFD references, and analog meters.
- Isolation protects the PLC from field transients on long cable runs.
- It is a practical choice for retrofits where panel space is tight.

FAQ
Q: Can I mix voltage and current outputs on one TM3AQ4?
A: Yes. You configure each channel in software. One channel can drive a 0-10 V valve, while another runs a 4-20 mA transmitter. This saves rack slots and spare parts.
Q: How do I know if the output is drifting over temperature?
A: Watch the ±1% full scale figure over temperature. In practice, check the reading at cold start and after the cabinet warms up. If drift matters, calibrate the loop after 30 minutes of run time.
Q: Does the TM3AQ4 need a separate power supply?
A: No. It draws 24 Vdc through the TM3 bus. It pulls 50 mA at 5 V DC and 80 mA at 24 V DC at full load. Check your bus power budget before you add more modules.
Q: What wiring should I use for 4-20 mA loops?
A: Use shielded twisted pair. Ground the shield at the panel end only. The 1500 V AC isolation helps, but good shielding still matters on long runs near drives. Keep the 5.08 mm terminal block screws tight.
Q: How fast does the output respond after a command change?
A: Budget 1 ms for conversion, 1 ms per channel, plus one controller cycle. Add 1 ms for stabilization. For most valve and VFD reference loops, this is more than fast enough. High-speed test rigs may need a faster card.
