The Schneider Modicon M310 TM310M35ECT26T is a current-production controller with 24 discrete I/O — 18 inputs and 6 transistor outputs, all sink-or-source configurable on the inputs. Cycle time runs 0.25 ms, so it handles fast logic and motion sequences without a separate co-processor. The 16 GB flash backup holds application data for six years at 25 °C, and the realtime clock drifts under 30 s/month, so you can skip battery swaps on the next PM. Communication covers Modbus TCP client/server, OPC UA client/server, Ethernet/IP adapter and scanner, and CANopen master — all built in, no extra gateway card. Fast inputs turn on in under 2.5 µs, letting you read incremental encoders or single-turn absolute encoders (up to two) directly on the base unit.
Mounts on a TH35-15 DIN rail per IEC 60715, or on a plate with the fixing kit. Vibration rating is 1 gn at 8.4–150 Hz on the DIN rail; panel mounting bumps that to 7 mm displacement at 5–8.4 Hz. Inputs and outputs connect via removable terminal blocks — supply, encoder, and serial links each get their own block. Input logic sinks or sources; the 24 V DC discrete inputs draw 5.2 mA each on the fast channels. Insulation between fast input and internal logic is rated at 550 V AC, with a pollution degree 2 environment. Surge withstand on the DC power lines is 0.5 kV common mode and differential mode per IEC 61000-4-5.
No cross-reference or direct sibling in this family; the base unit packs the I/O count and protocol mix you need without add-on modules.
