Analog I/O Features
The ABB DTEX742A offers 16 analog inputs with 14-bit resolution. You can configure each input for voltage or current independently. For outputs, the module provides 8 channels with 12-bit resolution. Therefore, you can connect a wide variety of sensors and actuators directly. The analog input impedance sits at 1 MΩ for voltage mode and 250 Ω for current mode.
Digital and Communication Features
This control module includes 16 digital inputs and 16 digital outputs. Each digital channel uses opto-isolators for electrical separation. The ABB DTEX742A also features two Ethernet ports for network redundancy. Additionally, it provides two serial ports (RS-232 and RS-485). Consequently, you can integrate this module into any industrial automation architecture.
Power and Energy Storage
The ABB DTEX742A draws 350 mA from a 24V DC supply. Hence, its total power consumption equals 8.4W. The three 220µF tantalum capacitors provide 12 milliseconds of hold-up time. This short backup protects critical configuration data during minor voltage sags. Furthermore, the module includes reverse polarity and overvoltage protection on its power input.
Installation and Connectivity
You can mount the ABB DTEX742A on a standard DIN rail. Alternatively, secure it with M4 screws through its four mounting corners. The two RJ45 ports accept standard Ethernet patch cables. The two 9-pin D-sub ports handle serial connections to legacy devices. The 50-pin header connects to field I/O termination boards. The ABB DTEX742A works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This industrial control module operates reliably from -20°C to +60°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 500 Hz. Therefore, the ABB DTEX742A suits harsh industrial environments perfectly.
