Digital Output Module Triconex 2755

Description

The Triconex 2755 Digital Output Module is an industrial control card designed for PLC/DCS control systems, suitable for critical automation applications like oil and gas industry safety control systems. It offers combined discrete and analog I/O capabilities, with 256 discrete inputs, 256 discrete outputs, 16 analog input channels, and 16 analog output channels. The module supports a total I/O data size of 36 bytes input and 36 bytes output, split into a base module with 4 bytes input/4 bytes output and an expansion module with 32 bytes input/32 bytes output.

Key performance specifications include a signal delay of less than 0.5 milliseconds and a response time of 10 milliseconds, ensuring fast, real-time control. It features LED status indicators for module, network, and I/O states, plus built-in I/O status diagnostic functions for quick fault identification. The module operates on a 24 VDC field power supply, with an input range of 11 VDC to 28.8 VDC, and includes reverse polarity protection with current limiting for 19.2 VDC to 28.8 VDC. Its 16-point relay output type supports a wide range of load voltages: 5 to 28.8 VDC, 48 VDC, 110 VDC, and 250 VAC, with trigger voltages of 9 VDC for on-state and 5 VDC for off-state. The supported bus length ranges from 100 meters to 1.2 kilometers, depending on the communication baud rate.
