SRE Developments offers a comprehensive range of control devices in DIN-mountable format.
The company manufactures its own patented DIN-rail pluggable modular timers in two-module width format. These timers are particularly suited to DIN D/B boards as they are the same size as a double pole DIN C/B. All the standard functions are available with a wide variety of standard time ranges and voltages. The standard timers are equipped with a 10 A single C/O relay and are either microprocessor or CMOS-based. Termination is via 2,5 mm pluggable terminals.
To facilitate higher-current applications, a full range of relays in PCB, pluggable and various interface combinations up to 30 A, as well as contactors above this current range, are available for inclusion in new designs or for replacement purposes. Upon request, SRE’s timers are also available in 11-pin plug-in format for replacement/maintenance purposes.
To complement these, SRE offers a range of Legrand DIN switches, indicators and time switches. All units are DIN-rail mountable and fit alongside any DIN circuit breakers. The switches include momentary or latching, changeover and stop start. These can be configured for momentary or latching by a unique adjustable mechanism on the side of the module, thus alleviating the need to carry double stock. The indicators are available in single, double or a combination of switch and indicator. No special tool is required for the changing of lamps as an innovative release mechanism is built into the lamp units. Switch buttons and indicator lenses are available in various colours and can be changed once the units are installed in the panel. Also available is a complete range of mechanical and electronic time switches in single and multiple DIN module widths.
SRE manufactures a range of lamp test, common alarm and alarm indication/control equipment in either PCB format or built up in a standalone enclosure. In addition to this, the company offers GSM communication from the alarm indication equipment. The GSM communicator is a two-way unit, which offers notification and control. In association with Autopage, a fully integrated computer room monitor is available which monitors room temperature, mains fail and restore, UPS failure and entry. Outputs/control for air conditioner, lighting and fire equipment are incorporated to drive externally installed power equipment.
The company also offers a comprehensive range of enclosures in PVC, polyester, stainless steel and powder-coated steel for numerous instrumentation and electrical applications. The protection ranges from IP44 to IP66 depending on application and specific models. Included in the range on offer are distribution boards ranging from 4-way PVC to 2000 mm high modular cabinets. The cabinets are versatile units which can be used for most process control or electrical equipment systems.
