The TM200C40U: It provides 24 discrete inputs (16 regular, 4 fast, 4 high-speed) and 16 transistor outputs (including 2 high-speed channels configurable for PWM/PLS). Built-in PID regulator handles up to 14 simultaneous loops, and four high-speed counters support quadrature, pulse/direction, single-phase, or CW/CCW modes at 100 kHz. Programming and monitoring via USB mini-B or RS232/485 serial link; default baud rate 115.2 kbit/s on RS485.
Mounting and I/O Layout
Mounts on TH35-15 or TH35-7.5 DIN rail per IEC 60715; dimensions 175 mm wide, 90 mm high, 70 mm deep. Removable screw terminal blocks for power supply (3-position), inputs, and outputs. I/O status indicated per-channel via green LEDs, plus dedicated PWR, RUN, ERR, SD, BAT, and SL1 LEDs. Inputs are sink/source type 1 per IEC 61131-2; output logic is negative (sink) with overload and short-circuit protection at 3.8 A.
High-Speed and Control Features
Response times: 1 ms on/off for normal outputs; 5 µs on/off for high-speed inputs; 35–100 µs for fast and regular inputs. Two fast outputs (Q0–Q1) generate PWM or PLS at up to 100 kHz, suitable for stepper or servo pulse-train control. Internal real-time clock with ≤90 s/month drift at 25 °C; backed by a BR2032 lithium battery with 5-year life and 3-year data retention without power. 512 bytes of internal flash store program backup, and the controller supports automatic restart (1 s reset time).
Specified against the listed ratings, the TM200C40U can be quoted to order for new designs or BOM line fills; no known obsolescence or substitution risk. Conforms to IEC 61131-2 and IEC 61010-2-201, carries CE marking.
