Individual Customized Solutions

 

Testing, measurement and automation tasks usually require specific, custom-made hardware solutions.

 

Delphin's many years of experience in developing custom systems for specific sectors or applications enables them to offer users customized systems in 19“-racks and/or instrument cabinets. This means each 19“-system and instrument cabinet is designed according to customer needs and technical requirements.

 

Alongside the Delphin components intended as measurement and control units for cabinets, third-party and external equipment may also be integrated into the system.

Measuring Systems According To Your Requirements

 

Delphin offers customized systems as both 19“-systems and instrument cabinets. Any requirement can be met from compact systems through to multiple linked cabinet installations.

 

19“-Rack Systems

Different products are used for 19“-rack systems. 19“-rack systems are generally delivered as 3 HE, 4 HE, or 6 HE, depending on the required connection capacity. Delphin deliver customized 19"-rack systems also to customers with special equipment or software requirements.

 

Cabinets

Delphin can deliver cabinets as small compact systems, as wall-mounted installations, and as multiple linked systems on bases at heights of 2000 or 2200 mm. Depending on user requirements, the signals and input / outputs can be wired as series terminals or as plug-in / integrated connectors, e. g. to a front panel.

 

Connector Panel 

Connector panels mounted directly at the test sample site have a proven record within test engineering and test stand systems. Because Expert or Message devices are usually directly installed at the connector panel, the panels represent a fast path from sensor to data acquisition and control systems. Communication to a PC or centralized test stand cabinet can then take place via network systems. Cabling is minimized and users get a better overview of the test stand.

 

Connector Technology

Connector technology is central for both cabinets and 19“-rack systems. Delphin can provide systems for any clamp, plug or integrated connector required. The connector technology used depends on user requirements, e. g. fixed or detachable wiring.

 

Sensor and Actuator Connectors can Be

Series terminals/screw terminals

Double terminals

Spring terminals

Plug-in screw and spring terminals

Feed-through screw terminals

4mm laboratory connectors, also as safety lab plugs

Lemo connectors (extensively used in the chemical sectors)

Thermominiature connectors irrespective of thermocouple type

BNC connectors

Multi-pole circular connector

Other connector technology

 

When required, Delphin can also integrate additional components such as an ICP-supply and power adapters. The connector technology is mounted to an engraved front panel. Connector identification is then still possible even after years of usage.

 

Function Testing and Safety

Each 19" rack or cabinet system of course complies to all relevant safety standards. A full earthing system is also present.

 

Documentation

Terminal layouts and connector and circuit diagrams are included with any new cabinet wiring installation. The required documentation is developed with the system and is included in delivery.
 

Functions

Special Applications

Delphin's Message and Expert hardware form the basis for the 19“-rack and cabinet systems. These are equipped with the analog and digital input / outputs required by the user. All Message and Expert device functions are also available for 19" rack and cabinet systems.

Analog Inputs

The universal inputs on Message and Expert devices are wired as plug-in connectors or connector sockets. Signals can be measured directly and without the need for measurement transducers:

Voltage signals

Current signals 0/4 .. 20 mA

Thermocouple type (K, E, N, L, J, S, U, R, T, B, C)

Resistance thermometer (Pt100/Pt1000)

 

Delphin can integrate additional components, such as an ICP-supply and power adapters, into housings or cabinet systems when required.

Digital Outputs/Switch Outputs  

Digital outputs / switch outputs are directly wired as clamps or plugs. The standard set up for switch outputs is as passive DC contacts with currents of up to 50 VDC and a permitted continuous current of 2.5 A. When required by users, relays and contactors may also be installed that can be directly controlled by the switch outputs.

Analog Outputs

Each analog output is assigned 2 clamps or plugs. Each channel can be used as a 0/4 ... 20 mA signal. Additional components installed within the cabinets, e. g. variable transformers or frequency converters, can be directly operated

Digital Inputs/Status Inputs/Frequency Inputs

Each digital input can be assigned 2 clamps or plugs. The standard digital input set up is passive with a high-level of between 3.5 V .. 90 VDC. Digital inputs can also be directly set up as 24 VDC contact inputs with a wired auxiliary supply of 24 V. This enables, for example, the acquisition of auxiliary contacts on relays.

Resistance Measurement

Resistance measurement of up to 10 kOhm is possible as standard. Connection at the universal inputs using 4-wire technology. There is also an option for a resistance measurement set up for measuring currents with an ampere. This enables high-precision measurement of the smallest resistances, e. g. contact resistances.

Alongside the Delphin measurement and control units in the cabinets, there are often also third-party and external equipment integrated into the system. This is especially the case for test stands.

Additional Components May Include

Contactors and relays

Voltage regulation

Variable transformers

DC power units

Power measuring units

Resistance measurement units

 

Frequency converters
