Output module packs suited for magnetic valves, pilot lamp applications

Simatic SM 326 F-DO 10 failsafe digital output module Siemens Industry is designed to improve system availability and isolate faults to individual channels.

01/10/2011


Siemens Industry Inc. has announced the introduction of a new space saving- and feature-packed Simatic SM 326 F-DO 10 failsafe digital output module.

Designed to interface with Siemens ET200M modular I/O stations and S7-300 and S7-400 safety-rated controllers, the new 24 V/2 A output module is only 40-mm wide – half the width of previous models.

The module allegedly improves system availability and eliminates nuisance-tripping with a “hold last value option” and by isolating faults to individual channels.

Enhanced diagnostic capabilities make the SM 326 F-DO 10 well suited for all safety applications, according to Siemens. Additionally, the module’s diagnostic capabilities have been extended to include both de-energized and energized to trip functions, which make it a cost-effective option for applications following fire and gas standards EN54 and NFPA72.

Designed for operator convenience, the module has the flexibility to support multiple types of I/O while still achieving up to a SIL 3 rating, even in mixed (standard and safety) configurations.

The SM 326-FDO 10 features 10 outputs, isolated in groups of five. Each module has an output current of 2 A per channel and a rated-load voltage of 24 V dc. With built-in protection against short-circuit and overload, the module is suitable for magnetic valves, dc contractors and pilot lamp applications.
