Digital Input Features
Each of the 16 input channels uses a dedicated opto-isolator for signal isolation. The ABB DTCC901B 61430001-FU accepts 24V DC signals from standard field sensors. Therefore, you can connect proximity switches, limit switches, and push buttons directly. The input current sits at 7 mA for reliable detection. Thus, the module presents a light load to your field devices.
Digital Output Features
The 16 output channels each provide 24V DC at 0.5 A maximum. Each output also includes a separate opto-isolator for protection. Consequently, a short on one output will not damage the processor. The output response time stays under 1 millisecond. The ABB can drive solenoids, relays, and indicator lamps easily.
Power and Energy Storage
The ABB draws 200 mA from a 5V DC logic supply. Additionally, it requires 24V DC field power for the outputs. Hence, the logic power consumption equals just 1.0W. The two 100µF capacitors provide 12 milliseconds of hold-up time. This short backup protects I/O states during minor voltage sags. Furthermore, the module includes reverse polarity protection on its field power input.
Installation and Connectivity
You can mount the ABB DTCC901B 61430001-FU on a standard DIN rail. Alternatively, secure it with M4 screws through its four corners. The two 25-pin D-sub connectors handle all input and output wiring. For reliable operation, use shielded cables for long signal runs. The ABB DTCC901B 61430001-FU works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This input/output 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 DTCC901B 61430001-FU suits most industrial automation systems perfectly.
