• Resolution: 12 bits – gives fine detection of signal changes.
• Accuracy: ±0.5% FS at 25 °C – reliable for process control.
• Linearity: ±0.4% FS – ensures consistent output.
• Temperature range: 0…55 °C operation, -25…70 °C storage.
• Environmental: IP20 protection, suitable for clean panels.
• Immunity: 50 dB common mode rejection reduces noise.

Installation & Setup

• Mount the module in a Twido base or rack.
• Use shielded twisted pair cables for analog signals.
• Connect the removable screw terminal block for I/O wiring.
• Supply external 24 V DC (20.4…28.8 V) to the module.
• Set jumpers (if any) to select voltage or current mode.

Compatibility & Integration

• Works with all Twido PLC controllers (TWDLMDA etc.).
• Also compatible with Modbus networks via the main controller.
• Supports both sink and source wiring conventions.

Typical Applications & Equipment

• Process monitoring: temperature, pressure, flow transmitters.
• Motor control: speed feedback from analog drives.
• HVAC systems: damper and valve position control.
• Packaging machines: fill level and tension control.
• Small conveyors and material handling systems.

Expert Review

• “The TWDAMM6HT is a workhorse for small analog tasks. The 12‑bit resolution and fast conversion make it great for real‑time control. The removable terminals speed up wiring. We use it in many compact panels.”
• – Senior Controls Engineer, Powergear X

Manager’s Insight

• “For cost‑effective analog expansion, this module delivers. It matches Twido’s reliability. Always check the output load range – staying within 300 Ω (current) or above 2 kΩ (voltage) ensures stable performance.”
• – Product Manager, Powergear X

Frequently Asked Questions

• What cable should I use?
  Use shielded twisted pair cable to reduce electrical noise.
• Can I mix voltage and current on the same module?
  Yes, each channel is individually configurable.
• How do I set the input type?
  You configure it via the PLC software (TwidoSoft) – no hardware jumpers for this model.
• What is the maximum load on the output?
  For current output: ≤300 Ω. For voltage output: ≥2 kΩ.
• Is this module hot‑swappable?
  No – power down the PLC before removing or inserting the module.
• What is the effect of temperature on accuracy?
  Input drifts 0.06% FS/°C, output drifts 0.5% FS/°C – keep the panel cool for best results.

Selection Guide

• Count the analog signals in your system – choose TWDAMM6HT if you need 4 inputs and 2 outputs.
• If you need more channels, consider adding additional modules.
• For high‑accuracy applications, use a separate power supply for the analog circuits.
• Always verify the output load before wiring to avoid signal distortion.
