ABB DOS810 - Digital Output Module

ABB DOS810 3BSE078768R1 Digital Output Module

Product Introduction

The DOS810 module brings single-channel granularity to your ABB System 800xA. It conditions digital output signals for 2-wire field devices. Additionally, this module sources 24V DC at 0.6A. You can use DOS810 in hazardous locations without extra barriers. Its compact design (77.9 x 105 x 9.8 mm) saves space. Furthermore, the module supports hot swapping for minimal downtime. Field technicians will appreciate the mechanical locking slider.

Technical Specifications

The DOS810 operates as a digital output SCM. It handles one channel per module. Key parameters include a 24V DC nominal voltage. The output current is electronically limited to 0.6 A. Moreover, this module provides galvanic isolation to the system. Factory routine testing reaches 3060 VDC. The power dissipation is only 0.36 W. DOS810 supports output load with max inductor time constant (L/R) of 50 ms over 40-5000 Ω.

Specifically, the input voltage range spans 19.2 to 30 V. Field input robustness is ±35 V between all terminals. Diagnostics include loop supervision for open and short circuits. Additionally, the module checks hardware, communication, internal power, and power injection. The OSP (Output Set to Predetermined value) function adds safety. You can configure DOS810 through software parameters.

Environmental and Certification Data

The DOS810 works in extreme temperatures from -40°C to +70°C. Storage temperatures range from -40°C to +85°C. Relative humidity can reach 5 to 95% non-condensing. Furthermore, this module carries multiple hazardous area approvals. These include ATEX II 3G Ex nA IIC T4 Gc and Ex ec IIC T4 Gc. IECEx and cULus certifications are also available. For marine environments, DNV and ABS approvals apply. The unit meets G3 corrosive atmosphere standards. Pollution degree is 2 per IEC 60664-1. Overvoltage category is II.

Mechanical Features and Installation

First, mount the DOS810 on a Select I/O base. The module measures 77.9 mm wide and 9.8 mm high. Depth is 105 mm, and weight is only 73 g (including base). Next, use the mechanical keying feature. This prevents insertion of wrong module types after commissioning. The mechanical locking slider turns off field power before removal. Additionally, the field disconnect function galvanically separates field wiring. This aids commissioning and maintenance tasks. You can hot swap DOS810 without powering down the entire system.

Benefits for System 800xA Users

The DOS810 decouples project tasks effectively. It minimizes the impact of late design changes. Standardization of I/O cabinetry becomes easier. Therefore, automation projects finish on time and under budget. Single-loop granularity means each SCM handles just one channel. You lose only one channel if a failure occurs. The built-in inductive load suppression uses a free-wheeling diode. Short circuit protection and wrong wiring protection are standard. All these features make DOS810 a reliable choice.

Frequently Asked Questions (FAQ)

1. Can the ABB DOS810 be used in hazardous areas?
Yes, the DOS810 carries ATEX, IECEx, and cULus approvals for hazardous locations. Specifically, it meets Class I, Division 2, Groups A-D T4 and Zone 2 requirements.

2. Does the DOS810 support redundancy?
Absolutely. The DOS810 offers full redundancy capability. This feature increases system availability for critical processes. You can configure two modules for the same channel.

3. What happens if I remove the DOS810 while powered?
The module supports hot swap. However, use the mechanical locking slider first. It safely turns off field device power before removal. This prevents arcing or damage.

4. How does the DOS810 handle a short circuit on the output?
The DOS810 is short circuit proof. Electronic current limiting activates at 0.6 A. Additionally, the module reports a short circuit via loop supervision diagnostics.

5. Is the DOS810 compatible with HART devices?
No, the DOS810 does not support HART communication. It is designed for standard 2-wire digital output devices only. For HART, consider other ABB Select I/O modules.
