ABB DSDI 110 57160001-A Digital Input Board

ABB DSDI 110 57160001-A Digital Input Board

Configured for high-density discrete signal acquisition and status monitoring in MasterPiece 200 and Advant OCS control systems, the ABB DSDI 110 (57160001-A Digital Input Board) provides direct physical/electrical execution.

Hardware Specifications

Process Control and Opto-Isolator Noise Immunity

Digital input boards route field contact statuses into central processing units for process interlocks and sequence logic. The DSDI 110 uses high-speed optical isolation across its 24 VDC channel inputs to prevent ground loops, electrical surges, and inductive switching noise from reaching the backplane bus. Signal filtering circuits eliminate contact chatter from field limit switches and relays, ensuring clean logic state updates within MasterPiece and Advant OCS system scan cycles.

Frequently Asked Questions

Q: What is the relation between part numbers 57160001-A and 3BSE018295R1?

A: Part number 57160001-A is the original manufacturing ID for the DSDI 110 board, whereas 3BSE018295R1 is ABB's modern replacement order code for the identical functional assembly.

Q: Can the DSDI 110 accept 110 VAC or 230 VAC field signals directly?

A: No. The DSDI 110 is rated strictly for 24 VDC opto-isolated inputs; higher AC voltages require interposing relays or dedicated AC input cards.

Field Installation Guidelines

• Shut down cabinet rack power before inserting or removing the DSDI 110 board to prevent backplane edge-connector arc damage.
• Wear an ESD grounding wrist strap connected to cabinet earth ground while handling the circuit card assembly.
• Slide the board smoothly along the rack guide rails until the rear edge connectors seat fully into the backplane socket.
• Tighten upper and lower card-retaining thumb screws to ground the front panel shield to the chassis rack frame.
• Verify 24 VDC field wiring polarity at the external terminal units before applying field power to input channels.
