ABB DO910S Digital Output Module S900 Ex

ABB DO910S (3KDE175321L9100) Digital Output Module

Product Introduction

The DO910S, also known as 3KDE175321L9100, belongs to ABB’s S900 I/O family. This module is specifically built for hazardous locations up to Zone 1. It provides four digital outputs for intrinsically safe field devices like valves and alarms. Additionally, the unit includes integrated driving power. Short circuit and wire break detection come as standard features. The DO910S also supports hot swap functionality, so you can replace it without shutting down the system.

Technical Specifications

This module delivers four isolated channels. Each channel drives a solenoid or an alarm indicator. The signal type is a solenoid driver with intrinsic safety protection. Furthermore, the DO910S ensures electrical isolation between output and bus, output and power, and also channel to channel. This design prevents cross interference.

Key parameters include:

• Channel count: 4

• Intrinsic safety: Yes

• Redundancy: No

• Electrical isolation: Channel to channel

• Short and break detection: Included

The module does not support Sequence of Events (SOE). However, it offers extended diagnostics and FDT/DTM configuration support.

Mechanical and Environmental Data

The DO910S has a very slim form factor. Its width is only 20 mm. Height and depth are both 104 mm. Net weight is 0.135 kg. Operating temperature ranges from -20°C to 60°C. Relative humidity can reach up to 93% at 40°C.

For harsh environments, all components receive a G3-coating. This coating meets ISA-S71.04 standards for corrosive atmospheres. Moreover, the module complies with CE, RoHS (2011/65/EU), and WEEE (2012/19/EU) directives.

Hazardous Area Certification

The DO910S carries ATEX certification for Zone 1 installation. You can install it directly in hazardous areas. It also connects safely to field devices located in Zone 0, Zone 1, or Zone 2. This flexibility reduces wiring and marshalling costs significantly.

In addition, the S900 I/O system can be placed in non-hazardous areas or Zone 1/2 depending on your variant. The entire system uses PROFIBUS DP for communication with the control level.

Installation and Maintenance

First, mount the S900 baseplate in your chosen location. Next, slide the 3KDE175321L9100 onto the rail until it locks. Then, connect the intrinsically safe field wiring to the appropriate terminals. Finally, power up the system and verify the LED status.

The DO910S supports hot configuration in run. This means you can change parameters while the system operates. Additionally, integrated disconnection mechanisms allow replacement during operation. You do not need to interrupt primary voltage. This feature simplifies maintenance and reduces downtime.

Frequently Asked Questions (FAQ)

1. Can I use the DO910S with non-intrinsically safe devices?

No. The DO910S is designed exclusively for intrinsically safe valves and alarms. Using it with standard devices violates safety regulations for Zone 1.

2. Does this module support redundancy?

No. The 3KDE175321L9100 does not include redundancy features. If you need redundancy, please check other modules in the S900 family.

3. Can I replace the DO910S while the system is powered?

Yes. The DO910S supports hot swap. You can remove and insert it without shutting down the primary power supply.

4. What happens if a channel breaks?

The module performs automatic short and break detection. It sends a diagnostic message to the control system. This feature helps you locate faults quickly.

5. Is the DO910S compliant with the latest RoHS standard?

Yes. This module complies with DIRECTIVE 2011/65/EU (RoHS 2). Unlike older spare parts, the DO910S is fully RoHS compliant for new installations.
