Product details

Controller overview and I/O configuration

The TM258LD42DT: Power consumption is 13.03 W from a 24 V DC supply rail (20.4…28.8 V limits). The main supply draws 0.25 A; the I/O power segment draws 10 A. Backplane power for embedded expert modules is 0.04 A. A CR2477M lithium cell backs up retain and retain-persistent variables for up to 1.5 years. The real-time clock, without calibration, drifts less than 30 s/month at 25 °C; with user calibration, drift is ≤ 6 s/month. Memory includes 128 MB flash and 64 MB internal RAM, sufficient for medium-size control logic with recipe storage and data logging.

Standards and compliance posture

The controller carries CE marking and is certified under CSA C22.2 No 142, CSA C22.2 No 213, UL 508, and IEC 61131-2. Pollution degree 2 per IEC 60664. Rated for IP20 (IEC 61131-2). Shock resistance 15 gn at 11 ms; vibration resistance 1 gn at 8.4…150 Hz on DIN rail (3.5 mm displacement at 5…8.4 Hz). Surge withstand is 0.5 kV differential mode and 1 kV common mode per IEC 61000-4-5. This is a current-production unit (lifecycle stage: current). Sourcing is through the standard Schneider Electric channel; RFQ for confirmed lead time and quantity pricing.

Mounting and physical placement

Local signaling includes one LED per I/O channel for state, plus dedicated status LEDs for CANopen (CAN0 STS), Modbus serial (MBS COM), two application LEDs (APP0, APP1), Ethernet network status (Eth NS), Ethernet activity (Eth LA), module status (RUN/MS), USB host, and battery (BATT). These LEDs match the M258 family layout.

Frequently asked questions

What certifications does the TM258LD42DT hold?
