ABB AC500 S500 DC522

16-Channel Configurable Digital Input/Output Module

DC522 is a compact AC500/S500 digital I/O module with 16 configurable 24 V DC channels. Each point can be used as an input, a transistor output or a re-readable combined I/O channel for flexible machine and plant automation.

Configurable I/O Each of the 16 channels can operate as a 24 V DC digital input, a 0.5 A transistor output or a combined I/O point whose output state can be read back by the controller.	Fast Counter Resources Inputs C8 and C9 form the fast counter input pair and C10 is the associated fast output. The specified maximum counter frequency is 50 kHz.
Output and Sensor Power Each output is rated to 0.5 A, with 8 A maximum total across all channels. Two protected 24 V DC sensor supplies provide 0.5 A total current per group.	Electrical Data Process supply is 24 V DC with maximum 5% ripple and an external 10 A fast fuse. Bus current is approximately 2 mA and unloaded power dissipation is up to 6 W.
Mechanical Integration DC522 requires a TU515 or TU516 terminal unit and mounts on a 35 mm DIN rail. The assembled envelope is approximately 67.5 x 135 x 84.5 mm; module weight is about 125 g.	Protection and Selection The IP20 module operates from 0 to 60 °C horizontally or 0 to 40 °C vertically with derating. Confirm DC522 and order number 1SAP240600R0001 before purchase.

I/O Functions

Configurable channels

Each of the 16 points can be engineered as a 24 V DC input, a 0.5 A transistor output, or a re-readable combined I/O point.

Fast counting

Channels C8 and C9 serve the fast counter input pair, while C10 is the associated fast output; the maximum counter frequency is 50 kHz.

Process feedback

Output states can be read back through the combined I/O function, supporting compact machine-control diagnostics.

Electrical Data

Process supply

The module uses 24 V DC process power with maximum 5% ripple and is protected externally by a 10 A fast fuse.

Load capability

Each transistor channel is rated to 0.5 A; the combined output current across all 16 channels is limited to 8 A.

Sensor power

Two short-circuit and overload-protected 24 V DC sensor supplies are provided, each with 0.5 A total group current.

Installation

Terminal unit selection

Install DC522 on a TU515 or TU516 terminal unit. The terminal unit provides field wiring and connection to the I/O bus.

DIN-rail mounting

Use a 35 mm DIN rail and maintain the specified 20 mm installation clearances for ventilation and wiring access.

Field wiring

Use shielded cabling up to 1000 m or unshielded cabling up to 600 m, subject to the installation and EMC requirements.

Environment

Temperature limits

Horizontal mounting permits 0 to 60 °C operation. Vertical mounting permits 0 to 40 °C with the documented output-group derating.

Enclosure requirement

The module is IP20 and must be installed inside a suitable control enclosure that provides the required protection.

Storage and humidity

The specified storage and transport range is -40 to 70 °C; relative humidity is up to 95% without condensation.

FAQ

1. How can a buyer confirm that the offered unit is exactly DC522?

Require clear photos of the front label and side label showing DC522 and order number 1SAP240600R0001. Confirm 16 configurable channels and compatibility with TU515 or TU516.

2. How can New, Used, and Refurbished DC522 units be distinguished?

Ask for dated photos of the housing, connector area, terminal contacts and packaging. New stock should not show field-wire marks, rail wear, dust or repaired output components.

3. How should the supplier for DC522 be qualified?

Verify the legal company identity, business address, traceable quotation, banking beneficiary and serial-number evidence. Match every document to DC522 before payment.

4. Which technical points must engineering verify before buying DC522?

Check 24 V DC supply, 16 configurable I/O points, 0.5 A per output, 8 A total output current, counter use on C8/C9/C10 and the required TU515 or TU516 terminal unit.

5. What physical evidence should be requested before payment?

Request current photos or video showing the complete label, order number, terminal contacts and packaging, plus a continuity or powered status demonstration when commercially agreed.

6. Can a similar DC-series suffix replace DC522?

No automatic substitution is valid. Channel count, counter mapping, output loading and terminal-unit requirements can differ, so engineering approval is required for any alternate model.
