The Schneider TM5SAO4L is a 4-channel analog output module on the Modicon TM5 platform. Outputs swing either 0-20 mA or ±10 V, selected per channel, making it a clean fit for driving VFD speed references, valve positioners, or chart recorders from a single 12.5 mm slot. Internal supply is drawn from the TM5 bus, pulling 63 mA from 24 VDC and 2 mA from 5 VDC — total dissipation 1.51 W. The module sits on a DIN rail with 500 Vrms isolation between channels and backplane bus. Response time ≤1 ms, sampling 300 µs, resolution 4.882 mV (±10 V) / 9.766 µA (0-20 mA), load impedance 200–500 Ohm. Vibration resistance rated at 1 gn on DIN rail (8.4–150 Hz) and shock 15 g / 11 ms. Ambient range 0–55 °C horizontal without derating, up to 60 °C with derating, or 0–50 °C vertically — check orientation in the panel layout.
TM5SAO4L vs TM5SAO4H
The TM5SAO4H is the high-resolution sibling. It reduces measurement error to <0.04 %FS (vs <0.08 %FS), sampling to 50 µs (vs 300 µs), resolution to 305.176 µV (voltage) / 610.352 nA (current), and temperature coefficient to 0.01 %FS/°C (vs 0.015 %FS/°C). If sampling faster than 300 µs or measurement error below 0.08 %FS is needed, choose the TM5SAO4H. Otherwise the TM5SAO4L suits, and both are active.
Panel Fit & Wiring
At 12.5 mm wide, the TM5SAO4L consumes minimal DIN rail space — four of these fit in 50 mm. Depth 75 mm leaves clearance for front-access wiring on the spring-cage terminals. Use shielded cable for the analog outputs as noted in the spec; ground the shield at the TM5 bus end to keep VFD noise off the signal. Each output can be independently configured as 0-20 mA or ±10 V. Current output must see a load between 200 and 500 Ohm; voltage output sees typically >10 kOhm. The module does not supply loop power — it’s a sourcing current output, so the loop must have its own supply if the load is passive (like an HART positioner). The green/red power LED and yellow output LEDs give quick visual status during commissioning.
The TM5SAO4L carries an Active lifecycle status. No last-time-buy, no successor part number — standard availability through the supply chain. If your BOM calls for this order code, it remains the current production variant without compatibility flags.
