Electrical & Operational Parameters

System Integration & Backplane Synchronization

The DSDO115 board interfaces directly with the host controller rack backplane, optimizing backplane bus communication velocity across high-channel applications. Operating within the deterministic logic loop of the host system, the unit supports scalable I/O density scaling while maintaining internal firmware flash compatibility to eliminate channel update latency across all 32 output circuits.

Delivery Package

• 1 x ABB DSDO115 57160001-NF Digital Output Board Assembly

Physical Installation & Cabling Regulations

• Rack Alignment: Insert the board into the designated S100 I/O card cage slot along the chassis guide rails until backplane connectors seat completely.
• Cabinet De-energization: Turn off the external 24 VDC field power source before connecting or disconnecting the front edge cable connectors.
• Cable Shielding Ground: Secure all field cable shields to the local station ground bus near the cabinet entry panel using low-impedance clamps.
• Thermal Spacing: Maintain clear vertical airflow paths above and below the card cage to prevent ambient temperature build-up across continuous 0.5 A loads.

Technical FAQ

• What is the maximum current capacity per individual output channel on the DSDO115 board?

  Each of the 32 discrete output channels handles up to 0.5 A continuous current under nominal 24 VDC operating conditions.

• Can the DSDO115 board be inserted into an active backplane slot while power is applied?

  No, hot-swapping is prohibited; de-energize backplane rack power and external 24 VDC field supplies before card extraction.

• What is the maximum voltage drop across an active channel operating at full load current?

  The forward on-state voltage drop does not exceed 0.3 V DC across any channel switching a 0.5 A load.

• How much off-state leakage current passes through an inactive channel circuit?

  The off-state leakage current across open output transistors is limited to a maximum of 10 uA.

• What external power source is required to drive the output field circuits?

  The board requires an isolated external 24 VDC auxiliary power supply connected via the field wiring distribution block.

• How does the board handle signal isolation between internal backplane logic and field wiring?

  Internal optical couplers provide galvanic isolation between low-voltage backplane logic circuits and 24 VDC field output channels.

• What storage temperature range is permitted for the DSDO115 circuit board?

  The card can be safely stored in unpowered warehouse environments within a temperature range of -55 deg C to +85 deg C.

• Is the 57160001-NF revision pin-compatible with standard DSDO115 base units?

  Yes, part number 57160001-NF identifies the specific manufacture revision, maintaining full pin-to-pin form factor alignment.
