Red Lion Converters

The Setpoint Model allows dual setpoint control capability through dual Form A relays. The analog model provides a retransmitted analog signal. A third model provides both analog and dual setpoint control capability. The power supply is universal, accepting 21.6 to 253 VAC/ 19.2 to 300 VDC as its power source. Add the optional programming module and the unit is easily programmed through menu style programming. The module can also be used to provide

Weidmuller Surge Protection for Low-Voltage Consumer Installations & Electronics Distributors
Low Voltage Supplies

for Low Voltage Supplies

Weidmuller surge protection products from the PU 1 series (Class I), PU 1 TSG, PU II series (Class II), PU III series and PO D (Class III) effectively reduce the surge protection even below the limits prescribed by the insulation coordination according to DIN VDE 0110. This means that the entire system is subjected to less interference.

The coordination of the arresters is achieved by technical means. This means that decoupling between classes I, II and III is not necessary.

Weidmuller VARITECTOR SSC EX Lightning & Surge Protection Distributor
VARITECTOR Series

Intrinsically safe circuits to limit energy are used in explosion risk zones. In these circuits, the intrinsically safe signal converters with their galvanic isolation and Exi approved surge arresters provide excellent protection for sensitive control electronics. Lightning strikes and overvoltages in the field on measurement and control cables can lead to explosions.

Surge voltages on the field side of the measurement and control lines can damage the facility. The VARITECTOR SPC EX can discharge surge voltages in hazardous area applications (zone 0, 1 and 2). The pluggable arresters conform the high requirements of the intrinsic safety Exi to the current standards. They also comply with the IEC 61643-21:2008 surge protection product standard and are certified for protection classes D1, C2 and C3. It provides lightning and surge protection at the maximum level ensuring unbiased measurement and control signals and is employable in process technical systems designed to the current norms and standards.

Instrumentation & Controls

If surge voltages are coupled onto transmission paths, sensitive signal inputs can be damaged or destroyed. It is important to provide protection in the vicinity of measurement and control devices. Weidmuller offers a comprehensive product line for the measurement and control industry.

This includes products with a two-part pluggable design or with a terminal design and with either screw or tension clamp connection type. These products work with both binary and analogue signals. Weidmuller also offers other models with integrated components such as gas discharge tubes or varistors.

Data Interface Protection

Data Interfaces

  • "Data transmission" is the transfer of characters, numbers, statuses, measurements, etc. between different, decentralised units.
  • "Decentralised units" are controls, Computers, measurement sensors, actuators, etc.
  • Appropriate overvoltage protection is essential for such sensitive areas.
  • Weidmuller can offer a wide range of solutions.
Weidmuller SPD II & SPD III DIN-Rail Mountable AC Surge Protectors Distributors
SPD Series

SPD Series

The SPD II range of surge protectors are used for transient surge protection of single and multi-phase power circuits at the main electrical panel. SPD IIIs are for the protection of individual electrical devices. They provide common-mode protection (between each Line and Ground), with impulse discharge capacity (Imax) 40kA for SPD II and 20kA for SPD III.

The SPD design is based on high-energy varistors (MOVs) equipped with thermal disconnects and integral failure indicators. A remote signaling contact for disconnection indication is standard on each unit. For ease of replacement, varistors are housed in pluggable modules with connections that are mechanically keyed to the base to prevent incorrect arrestor module replacement. Typical applications include low voltage distribution, or protection of industrial control systems, equipment assemblies and devices.

MTL SD Series Surge Protection for Data & Signal Applications Distributor
SD Series

SD Series

The SD Series is a range of surge protection devices combining unparalleled packing densities, application versatility, proven reliable hybrid circuitry, simple installation and optional 'loop disconnect' facilities - features which make the series the ultimate surge protection solution for process equipment, I/O systems and communications networks. The exceptionally high packing densities are the consequence of an ultra slim 'footprint' for individual modules which can thus 'double-up' as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection.

  • SDX - Available in 7V, 16V, 32V & 55V versions
  • SD - Fused protection against fault currents
  • SDR - For high speed data links
  • SD32T3, SDRTD, SDR3 - The most compact 3-wire surge protector on the market
Cooper Crouse Hinds SLP Series Multi-Stage Hybrid Surge Protection Distributors
SLP Series

SLP Series

MTL Instruments multi-stage hybrid of the SLP Series uses a combination of solid state electronics and a gas filled discharge tube (GDT) to provide surge protection up to 20kA. The SLP series is designed to exhibit exceptionally low line resistance and adds only a tiny voltage drop to the circuit. In operation, the SLP device does not adversely affect the performance or operation of the loop or combined equipment. The device allows signals to pass with very little attenuation while diverting surge currents safely to earth and clamping output voltages to safe levels.

MTL MA15 Series AC & DC Power Surge Suppressors & Mains Filters Distributor
MA15 Series

MA15 Series

The MA15 Series of surge protection devices protects electronic equipment and computer networks against the effects of 'noise pollution' induced in mains power supplies. MA15 units 'clean up' the effects of industrial noise and surges caused by lightning, switching devices, thyristor controls, transmission system overloads and power-factor correction circuits.

Industrial control systems utilising programmable logic controllers (plc) and industrial computers are particularly vulnerable due to the aggressive electrical environments for which they are intended, such as process plants, factories and water treatment sites. Although industrial computers and plcs are designed to be rugged, the extra protection provided by the DIN rail mounting MA15 units is critical.

Cooper Crouse Hinds TP Series Surge Protection Devices Distributors
TP Series

TP48 Series

The TP48 surge protection device safeguards field-mounted process transmitters where it matters, right at the unit. After a simple installation (the TP48 screws into an unused conduit entry, with no additional modification), it provides high-level protection against surges and transients whilst normal operation remains unaffected.

The TP48 resets itself automatically after each operation. The TP48 is available with screw threads to suit different transmitters, with explosion proof and intrinsically safe options for hazardous areas. Working voltage is 48V dc maximum with impulse ratings of 10kA peak current and 10kV peak voltage.
