TWDPTO220DT
— PTO Module · 2-Channel Pulse Train Output
Product Overview
TWDPTO220DT is a 2-channel PTO extension module for precise motion control.
It generates square-wave pulses with programmable count and cycle time.
Supports single or multi‑train pulse profiles (ramp up/run/ramp down).
Open‑loop positioning – no feedback needed; servo‑drive handles position loop.
Ideal for stepper motors and servo drives in Modicon Quantum systems.

- Frequency response: 200 kHz per channel, 50% duty cycle standard.
- Resolution: pulse count programmable up to 2³²‑1 per train.
- Linearity: ±0.1% of set frequency (within 10 Hz ~ 200 kHz).
- Environmental tolerance: 0 ~ 55 °C, 10 ~ 95% RH (non‑condensing).
- Noise immunity: > 1 kV surge (IEC 61000‑4‑5), fast transient burst 2 kV.
- Shielded cables mandatory for inputs/outputs to maintain EMC performance.
- Output compatibility: RS422 standard (CW/CCW), 7 mA/pulse, max 20 mA.
Installation & Maintenance
- Mounting: DIN‑rail or direct panel mounting (use M4 screws). Keep cables < 3 m.
- Wiring: Use shielded cable for all I/O (PTO, inputs, outputs).
- Grounding: Connect shield to ground at both ends (or as per local code).
- Maintenance: No routine calibration; periodic check of supply voltage and connectors.
- Diagnostic LEDs: On‑board status for PTO active, input state, output fault.
- Firmware: Field‑upgradable via USB‑UART (tool provided in kit).
Compatibility: Works with Modicon Quantum backplanes via expansion bus. Also compatible with M340, M580 series. Requires EcoStruxure Control Expert v15+ for configuration.
Package & Warranty
- In the box: TWDPTO220DT module, 10‑pin connector kit, quick start guide, software CD (configuration tool).
- Warranty: 12 months against manufacturing defects.
- Shipping: FedEx, UPS, DHL – worldwide express (tracking included).
- Obsolete support: We offer tested refurbished units for legacy systems.
Applications & Diagnostics
- Typical use: Stepper motor ramp‑up/run/ramp‑down, servo drive pulse train, conveyor indexing.
- Diagnostic features: Real‑time pulse count verification, output short‑circuit detection, under‑voltage lockout.
- Fault monitoring: Monitors DRV_READY, LIMIT, ORIGIN; triggers safe stop on fault.
- FAQ – Quick answers: Can I use unshielded cable? Not recommended – use shielded for reliable operation. Max cable length? 3 m for all ports.
- What is the minimum load current? None (open‑collector output).
- Does it support A/B phase? Yes, up to 100 kHz per channel.
