STC5 – the Next Level in Intrinsically Safe Transmitter Power Supplies

The Pepperl + Fuchs STC4 range of transmitter power supplies will no longer be available from the end of December 2021, it’s time you considered switching to the more advanced and far more capable STC5 Models.

STC5 – The Next Level in Transmitter Power Supplies

The innovative STC5 transmitter power supply isolation barriers and signal conditioners have been designed for the protection of intrinsically safe circuits in hazardous areas providing galvanic isolation between field circuits and control circuits. Feature-packed, the STC5 provides current and voltage limitations and electrical isolation (in a diminutive 20 mm housing) between a field circuit and control mechanism in an intrinsically safe installation.

Flexible, Dependable, Reliable

Designed to last, the STC5 range of transmitter power supply isolation barriers and signal conditioners offers more flexibility than their predecessors, using a double output function to the control side. Advanced circuitry with reduced power dissipation in the device when in sink output mode lowers cabinet temperatures, leading to an increased lifetime of the installed modules.

STC5– Ideal for high-channel density installations

  • Highest packing density on the market
  • High power dissipation capability
  • Connectivity for 3-wire transmitters
  • Supplies 2-wire and 3-wire SMART transmitters
  • Can be used with 2-wire SMART current sources
  • Digital signals may be superimposed on the input signal and transferred bidirectionally
  • Sink mode or a source mode output on the safe area terminals
  • Internal resistor if the HART communication resistance in the control circuit is too low
  • Test sockets for the connection of HART communicators integrated into the device terminals

SIMOCODE pro System– the best in Motor Control, Monitoring and Protection

The powerful Siemens SIMOCODE pro system has been managing low-voltage motors for over 50 years, providing comprehensive protective, monitoring and control functions for a wide variety of motors in numerous industrial applications.
SIMOCODE is suitable for switching heavy-starting motors in industries such as paper, cement, metal and water management, and also In ATEX rated areas including chemical, oil, and raw material processing and power plants. Conventional dry-run detection follows a response chain from the dry-run sensor to the pump via the process controller. The SIMOCODE pro System differs by monitoring the pump’s status via its active-power input so no need to install additional monitoring devices or external measuring sensors.

Designed to excel the SIMOCODE pro System can control numerous devices, such as a direct-online starter, reversing pair, soft starter and star-delta starter which covers the majority of fixed speed applications up to 630 amps.

Motor Control Advantages
• Higher measuring accuracy
• Earlier fault detection
• Reduced hardware
• No maintenance effort
• Cost and time savings
• Reliable plant monitoring according to ATEX and IECEx criteria

Plant downtime can be drastically reduced through the stored operating, service and diagnostic data that helps engineers identify faults and processing anomalies quickly, saving on process downtime and ultimately production costs. Packed with innovation, the SIMOCODE pro system provides communication via PROFIBUS, PROFINET / PROFIsafe, Modbus RTU, and Ethernet IP and OPC UA – which lets engineers take advantage of the cloud.

With OPC UA, SIMOCODE pro offers a flexible and powerful communication interface via Industrial Ethernet for automation as well as operation and monitoring systems. Acting as OPC UA client, these systems can access all important operating, service and diagnostics data of SIMOCODE pro for PROFINET and transfer control commands via the integrated OPC UA server. The motor management system directs information from the control panel via Ethernet right to where it is processed: directly-on-site on HMI Panels or across multiple systems in higher-level cloud-based solutions.

Case Study: Carlsberg’s Clever(Level) Overflow Switch

Industrial, Commercial and Domestic Fuses – A Closer Look Part 1

Intrinsically Safe Isolation Barriers – From Pepperl + Fuchs

Intrinsically Safe Isolation Barriers limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres. This simplifies the maintenance and repair of Ex i circuits.

There are 2 types of classifications for intrinsically safe equipment, Ex ia is designed to be safe with 2 independent faults and can be used in Zone 0.  Ex ib has a lower level of integrity and cannot be used for Zone 0 and the circuit design contains fewer zener diodes which is suitable for use in Zones 1 or 2.

Pepperl+Fuchs offers a variety of Intrinsically Safe Isolation Barriers designed for a variety of requirements.

 

Isolated Barriers

Isolated Barriers

In addition to their explosion protection function, Isolation Barriers offer galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. These interface modules also convert, standardise and split measurement and control signals.

Intrinsically Safe Isolation Barriers are the core of Pepperl+Fuchs product portfolio, with the widest selection of products for the protection of electrical signals located in hazardous areas. These intrinsic safety modules combine the energy limiting features of a zener barrier with galvanic isolation.

The K-System

Found in a wide range of applications these Intrinsic Safety Isolation Barriers are flexible DIN rail mounted modules. The K-System barriers connect easily with P+F Power Rail assemblies on the DIN rail, using the Power Rail reduces the wiring by energising the modules mounted on to the DIN rail.

The H-System

The H-System Intrinsically Safe Isolation Barriers are mounted on termination boards and are ideal for applications requiring tight Distribution Control System (DCS) or system integration.

 

Zener Barriers

Zener Isolation Barrier

Zener Isolated Barriers prevent the transmission of excessively high energy levels from the non-explosion hazardous area to the hazardous area. These interface modules are the perfect choice when galvanic isolation is not needed or provided.

 

Zener Barriers – Cost Saving and Easy Mounting Ex-Protection

Zener Barriers provide cost saving Ex-protection for various applications in process automation systems. The amount of energy transferred to the hazardous location is limited to a safe level incapable of igniting an explosive atmosphere.

Pepperl+ Fuchs Z-system Zener Barriers are directly mounted on a 35 mm DIN-Rail and with additional accessories grounding can be done directly on to the DIN mounting rail.

  • Fast mounting on DIN-rail
  • Grounding directly connected with DIN-rail
  • Separation of field-loop by removing the fuse

Z-system Zener Barriers are available with high-density with up to 2 channels and have a width of 12.5 mm. Variants with field replaceable fuses provide a convenient means of disconnecting or open-circuiting the instrument loop without interfering with the wiring, making commissioning and maintenance operations much easier.
