For clear network signals!

Three-phase interference suppressor filter for measuring applications Voltage peaks and high-frequency interference voltages of a wide variety of causes can spread nearly unhindered in the system. If they collide with sensitive measuring inputs, this causes faulty measurements and, in the extreme case, the destruction of the measuring unit. This problem can be smartly solved by using the three-phase interference suppressor filters MK 5130N and LG 5130 from the VARIMETER series from DOLD. The...

Multifunctional measuring relay

VARIMETER PRO saves cost, space and wiring With the MK 9300N of the VARIMETER PRO series, DOLD combines up to nine monitoring functions in a housing only 22.5 mm wide. This universal measuring and monitoring relay thus offers a functional diversity unparalleled so far at this minimal unit width. Troublefree and economic operation of machines and systems is guaranteed only by the reliable and continuous monitoring of three-phase systems. Depending on the need, the VARIMETER PRO therefore...

More space, more flexibility

Electronic housing with variable connection method Dold complements its innovative KS 4400 housing series by a 6.2 mm narrow version. In addition, flexibility was further expanded. The modular housing system now also offers a sealable, transparent front cover. It protects memory cards, socket connectors and adjusting elements reliably against manipulation and accidental wrong settings. The housing system, available in many colours, offers a wide range of application and design options....

Switching up to 88 A while saving space!

Semiconductor relay/ contactor With the new semiconductor relay PK 9260 of the POWERSWITCH series from DOLD, ohmic loads can be switched economically. With its long service life, due to wear-free switching, it is especially suitable for applications with high switching frequencies. The many different application options include, for example, extruder machines, injection moulding equipment and heaters. The 1-pole semiconductor relay switches at zero voltage thus possessing superb EMC...

Flexible, simple, secure!

The new IN-RAIL-BUS from DOLD The IN-RAIL-BUS system from DOLD, developed for electronics housings, is a universal and continuous mounting rail bus. As economic alternative for elaborate single wiring, the bus system is especially suitable for data transfer and power supply of different devices and assemblies in a group. The base of the IN-RAIL-BUS system is a carrier section that can be easily integrated into a top hat rail. It accommodates the BUS PCB, that can be individually designed and...

Safety switch and key transfer system - SAFEMASTER STS

SAFEMASTER STS is a modular safety switch and key transfer system made of long lasting stainless steel. It is designed to be used on guard systems with gates and covers and combines the advantages of a safety switch, solenoid lock and key transfer in one system. One of the most important advantages is the protection  against being locked in by means of a safety key. Safemaster STS allows electrical monitoring of the main access gates. Other seldom used doors, e.g. for maintenance are...

INFOMASTER reduces standstill times

Extendable fault annunciator system for plants and buildings The compact new -/first-message annunciator system INFOMASTER B of DOLD allows fast and economic localisation of failures in plants and buildings. A lot of time is saved when faultfinding and the failure reasons are detected. The special highlight of this system is its bus structure. It allows individual solutions for all applications up to 88 fault inputs. The functions new message, first  message and common alarm can be...

Self monitoring solid state relay The compact DOLD solid state relay POWERSWITCH PH 9270 has integrated monitoring functions and is suitable for high frequency operation. It switches wear free, noiseless and has a nearly unlimited service life. In addition it offers significant cost saving and increased availability with it’s intelligent monitoring functions. Among various other applications it can be used for critical heater controls in plastic and rubber manufacturing as well as in...

This will convince you!

Wireless E-stop function The innovative DOLD Safemaster W with BG- approval offers additional safety when entering mobile and stationary machines and plants especially with large or unobserved dangerous areas. The safety details are performance level (PL) “e” according to DIN ISO 13849-1 and safety category 4 according to DIN EN 954-1. Using a remote control, dangerous movements can be stopped safely in shortest time via radio connection. The main components are a  ompact,...

Reliable fire and system protection

Differential current monitor type B with pre-warning function Early detection of insulation faults can prevent failure of complete electrical plants. Fault current monitoring by measuring differential current is the ideal method for  his application. The monitoring requirement for today’s supply systems get more and more complex. Electronic control of drives, switched power supplies and  chargers or fluorescent lamps with electronic ballast units can create DC fault currents...
