The Telemecanique TWDDMM8DRT is a discrete I/O module that forms part of the Twido series, renowned for its reliability and versatility in automation systems. This module is designed to cater to a variety of industrial applications requiring discrete control. It features four 24 V DC inputs and four relay outputs, making it suitable for interfacing with sensors, actuators, and other control elements.
Each input of the TWDDMM8DRT module is capable of sink or source logic, providing flexibility in connecting different types of field devices. The input voltage range of 20.4 to 28.8 V DC and an input impedance of 3.4 kOhm ensure compatibility with a wide range of sensors. The module also boasts a filter time of 8 ms for both state 0 and state 1, which helps in debouncing signals and ensuring stable operation.
The relay outputs are designed as 4 Normally Open (NO) contacts, with a current rating of 2 A per channel and a collective rating of 7 A per output common. This allows for direct control of various loads. The response time of less than 7 ms ensures quick action upon receiving a command, which is critical in time-sensitive applications.
With a compact design and a removable screw terminal block, the TWDDMM8DRT module ensures ease of installation and maintenance. The module's insulation between channels and internal logic is rated at 1500 Vrms for 1 minute, provided by a photocoupler, which enhances the safety and durability of the module.
The Telemecanique TWDDMM8DRT operates within an ambient air temperature range of 0 to 55 °C for operation and -25 to 70 °C for storage, making it suitable for harsh industrial environments. It also carries CE marking and has a product weight of 0.095 kg, reflecting its solid build quality and compliance with European standards.
This discrete I/O module is an excellent choice for those seeking a robust and reliable solution for their discrete control needs in industrial automation systems.
