Product Description:

The DEA 4.2 is a Digital Interface Card from the VT-UK2 universal card series of Bosch Rexroth Indramat. The card delivers standardized digital input and output functions for industrial automation tasks. Its front panel contains a multi-pin connector that ensures dependable data exchange. An ERR status LED is integrated on the front to indicate faults or error conditions.

The DEA 4.2 interface card functions with a stabilized DC power source within specified tolerances. The operating input voltage is usually +5 V DC with acceptable variation. Current draw is maintained within defined safe operating levels. Encoder connectivity is designed for digital incremental encoders operating with TTL logic signals. Its encoder frequencies extend up to several hundred kilohertz, depending on the application. The resolution level is determined by the encoder setup and pulse per revolution values. This allows precise position monitoring and secure transmission of control signals. The environmental ratings of the DEA 4.2 interface card make it suitable for industrial settings. The allowable operating temperature range extends from 0 °C to 50 °C without derating. The storage temperature band is broader to cover transport and inactive periods. The vibration capacity is 0.15 mm amplitude across 10 to 55 Hz.

The DEA 4.2 interface card withstands shocks up to 10 g over brief intervals. Installation altitude is rated to 1000 meters above sea level without a reduction in capacity. The cooling requirements are met through natural convection inside control enclosures. The dimensions and weight conform to VT-UK2 standards for modular integration. The card interfaces through X1 and X17 connectors for secure electrical connections. Its compliance with EMC requirements ensures dependable performance under electromagnetic disturbance. Its permissible humidity is up to 95 percent relative, non-condensing.
