ABB AC500 S500 DC523

24-Channel Configurable Digital Input/Output Module

DC523 provides a high-density set of 24 configurable 24 V DC digital channels for AC500/S500 systems. Individual points can be assigned as inputs, transistor outputs or re-readable combined I/O to suit the exact field-signal layout.

High-Density I/O All 24 points can be configured individually as 24 V DC inputs, 0.5 A transistor outputs or combined I/O channels with output-state readback.	Counter Assignment The integrated fast counter uses inputs C16 and C17 together with output C18 and supports frequencies up to 50 kHz.
Load and Sensor Supply Each output supports 0.5 A and the combined channel current is limited to 8 A. The protected 24 V DC sensor supply provides 0.5 A total current.	Electrical Data The module uses 24 V DC process power with maximum 5% ripple and an external 10 A fast fuse. Bus current is approximately 2 mA and unloaded dissipation is up to 6 W.
Mechanical Integration Use DC523 with a TU515 or TU516 terminal unit on a 35 mm DIN rail. The assembled size is approximately 67.5 x 135 x 84.5 mm and module weight is about 125 g.	Protection and Selection IP20 construction requires a control enclosure. Horizontal operation is 0 to 60 °C; vertical operation is 0 to 40 °C with derating. Verify DC523 and order number 1SAP240500R0001.

I/O Functions

High-density mixed use

All 24 channels may be configured individually as 24 V DC inputs, 0.5 A transistor outputs, or re-readable combined I/O points.

Counter assignment

The fast counter uses inputs C16 and C17 with output C18 and supports frequencies up to 50 kHz.

State verification

The combined I/O design allows configured output states to be read back for control and diagnostic functions.

Electrical Data

24 V DC power

DC523 is supplied from 24 V DC with a maximum allowed ripple of 5%; ABB specifies a 10 A fast external fuse.

Output budget

Each output supports 0.5 A, while the combined current across all 24 configurable channels is limited to 8 A.

Sensor circuit

The integrated 24 V DC sensor supply is short-circuit and overload protected and provides 0.5 A total.

Installation

Terminal unit

Use DC523 with the ABB TU515 or TU516 terminal unit for I/O-bus coupling and field termination.

Mounting method

Mount the assembled module on a 35 mm DIN rail with the specified 20 mm clearance for heat dissipation and cable routing.

Signal cabling

ABB specifies maximum lengths of 1000 m for shielded signal cable and 600 m for unshielded cable.

Environment

Operating orientation

Horizontal mounting supports 0 to 60 °C. For vertical mounting, the limit is 0 to 40 °C with the stated group-current derating.

Protection

IP20 construction requires installation in a suitable industrial control cabinet or enclosure.

Storage conditions

Storage and transport are specified from -40 to 70 °C, with humidity up to 95% and no condensation.

FAQ

1. What confirms that a quotation is for DC523 rather than another DC module?

The label must state DC523 and order number 1SAP240500R0001. Verify the 24 configurable channels, C16/C17/C18 counter assignment and TU515 or TU516 requirement.

2. What evidence separates a new DC523 from used or refurbished stock?

Review dated high-resolution images of the label, rail latch, terminal contacts and housing. Field wiring marks, oxidation, dust or replaced components indicate prior use or repair.

3. How can procurement assess a DC523 supplier?

Check the registered business entity, address, quotation history, beneficiary account and ability to provide traceable label and serial-number evidence before funds are released.

4. Which DC523 specifications require engineering confirmation?

Confirm 24 V DC supply, 24 configurable points, 0.5 A channel rating, 8 A total output limit, 50 kHz counter requirement and the intended TU515 or TU516 terminal unit.

5. What should be photographed before payment for DC523?

Ask for a current photo set showing the complete front and side labels, order number, terminal contacts, packaging and all included accessories.

6. May DC522 or another suffix be substituted for DC523?

Not without an engineering review. DC523 has 24 channels and a different fast-counter channel assignment, so channel mapping and application loading must be rechecked.
