Schneider TWDAVO2HT Twido Analog Output Module

TWDAVO2HT Dual-Channel +/-10V Analog Output Module

Product Introduction

The Schneider Electric TWDAVO2HT analog output module provides a robust solution for controlling bidirectional analog devices within your Twido automation system. This expansion module generates two independent +/-10V voltage outputs, making it ideal for applications that require control in both directions, such as motor speed regulation for forward and reverse operation or valve positioning with reversal capability. It operates on a standard 24V DC supply and mounts easily on a DIN rail, ensuring seamless integration into existing control panels. The module also includes short-circuit and overload protection, along with status LEDs for quick diagnostics.

Key Technical Specifications

The TWDAVO2HT excels in providing precise two-polarity voltage control. Its two analog outputs deliver a range of -10V to +10V, which distinguishes it from standard unipolar output modules. The output resolution is 11 bits plus a sign bit, providing an LSB value of +/-9.8 mV for fine-grained control. This level of resolution ensures smooth and accurate actuation for processes demanding bidirectional analog signals.

Additionally, this output module supports resistive loads with a maximum impedance of 3000 Ohms, offering broad compatibility with various field devices. The removable screw terminal block simplifies wiring and future maintenance, while galvanic isolation between the output channels and internal logic enhances system safety and protects your controller from potential electrical faults. The module conforms to IEC/EN 61131-2 standards and carries UL and CSA certifications.

Performance and Accuracy

Accuracy defines the performance of the TWDAVO2HT output module. At 25 °C, the measurement error stays within +/- 0.5% of full scale for voltage outputs. The non-linearity is equally impressive at +/- 0.2% of full scale, ensuring your output signal faithfully represents the commanded value.

The temperature coefficient is remarkably low at +/-0.01 %FS/°C, meaning temperature variations have a negligible effect on output accuracy, making the TWDAVO2HT suitable for environments with fluctuating temperatures. The output ripple stays at or below 1 LSB for a clean, stable signal. Stabilization time reaches just 2 ms, enabling rapid response to control commands.

Mechanical and Environmental Parameters

The Schneider TWDAVO2HT withstands harsh industrial conditions with ease. Its IP20 protection rating makes it appropriate for installation inside control cabinets, guarding against solid objects larger than 12.5mm. The module operates reliably across an ambient temperature range of 0 to 55 °C and withstands storage temperatures from -40 to 70 °C. The relative humidity tolerance spans 10% to 95% non-condensing.

The module features compact dimensions of 90 x 23.5 x 70 mm and weighs only 85 g, saving valuable space in your control cabinet. The rated insulation voltage reaches 500V AC, ensuring robust electrical isolation between the outputs and the supply circuit.

Installation Guidelines

Installing the TWDAVO2HT follows a straightforward procedure. For optimal signal integrity, use shielded twisted-pair cables for all analog output connections to prevent electromagnetic interference. The removable screw terminal block makes wiring simple and convenient. The module mounts on a standard DIN rail and requires no specific configuration for basic operation. Before connecting the module, verify that the power supply falls within the specified voltage limits of 20.4 to 28.8V DC. The recommended tightening torque for terminal block connections is 0.22-0.25 N.m.
