ABB DSAX452 Remote In/Out Basic Unit

The ABB DSAX452, also cataloged as the DSAX 452 Remote In/Out Basic Unit, operates as a dedicated hardware component for mixed analog signal acquisition and output execution within MasterPiece and Advant Controller platforms.

Hardware Specifications

Backplane Bus Communication Velocity & Mixed Analog Signal Processing

The module utilizes high-speed backplane bus communication velocity and firmware flash compatibility to deliver deterministic analog data acquisition across distributed I/O racks. Integrated channel isolation protects the internal 12-bit input and 10-bit output conversion circuitry from field-side electrical noise, voltage transients, and signal degradation across standard 0 to +/-10 VDC and 0 to +20 mA loops.

Frequently Asked Questions

Q: What analog signal ranges and channel counts are supported by the ABB DSAX452?

A: The DSAX452 integrates 14 differential analog input channels (12-bit resolution, 0 to +/-10 VDC or 0 to +/-20 mA) and 6 analog output channels (10-bit resolution, 0 to +10 VDC or 0 to +20 mA).

Q: What is the physical weight of the DSAX452 Remote In/Out Basic Unit?

A: The module has a net physical weight of 2.7 kg.

Field Installation Guidelines

Ensure subrack power is completely de-energized before inserting or removing the module to protect edge connector contacts from electrical arcing. Use twisted, shielded cabling for all analog input and output wiring, routing signal cables separately from high-voltage AC power lines to avoid capacitive or inductive cross-talk. Cable shields must be terminated at a single-point low-impedance earth ground, and terminal block attachment screws must be torqued securely.
