Kalbadevi, Mumbai, Maharashtra

Accumulating commendations from all over, we are placed among the top figures in the industry Speed Monitor Relay on offer is available in a wide variety of designs and sizes. It is used for monitoring the rotation of drives for generating a control signal at zero speed or when it exceeds a set speed. Superior technology and high tech machinery are used for its manufacturing.

Advantages

• Prewired rail-mounted modules
• Safety category 3 acc. to EN 954-1
• Positively driven output contacts
• Connection monitoring of the proximity switches

TechnologyThese modules have measuring circuits in redundant configuration with 2-channel control by proximity sensors, either as pnp or npn input. The thresholds are either fixed or can be adjusted up to 26000 IPM. Zero-speed monitors can also work without sensors by measuring the remanence voltage of the coasting motor and evaluating it at zero speed.

Applications

• Release safety gate interlocks when the stationary condition of a dangerous movement is detected.
• Work with opened safeguard devices and reduced speed during the set-up mode of the machine.

As a well-known player in the industry, we enable ourselves to present a wide range of Measuring Relay to our customers. The quality on offer is unmatched as we take meticulous care of quality by testing it against the highest grades of quality set by the industry. We also provide an option to deliver at your doorstep at your ease owing to our first-rate distribution system for pocket friendly rates.

Additional InformationDOLD measuring devices reliably monitor electrical quantities such as current, voltage, power, resistance etc. and signal fault conditions and disturbances. Thus, these products also protect complex systems and ensure an optimal production sequence. LEDs on the front provide visual status indications. Output contacts or interfaces to bus systems allow information transmission.

AdvantagesCustomers benefit from DOLD's complete functional range. Our experienced engineers give you proficient advice when it comes to the selection of products perfectly tailored to customers' requirements for a variety of monitoring and measuring applications. It goes without saying that also customer-specific adjustments are possible (e.g. modification of voltage ratings, contact materials, etc.). So we offer solutions optimized for your monitoring and measuring requirements - all from one hand. Our competitive edge becomes yours. We offer both mono- and also multifunctional relays allowing our customers to configure at their own discretion solutions either with a minimum of investment or also with a maximum of flexibility and functionality.
