Accurate and precise temperature control from any computer – West / CAL 9500 P

Accurate and precise temperature control from any computer

West Control Solutions presents a uniquely versatile and affordable programmable controller for temperature and process control applications, CAL 9500P.  Compatible with, the controller is complemented with data logging, process data archiving, chart recording, virtual instrument display and on screen alarms so you can monitor and control your equipment from any computer connected to your process network.cal9500

 Profiles can be created easily on both the front panel and via CALgrafix software. The step-by-step HMI structure for intuitive configuration of the controller, allows memory to be freely allocated for programs up to 126 segments or up to 31 programs.

CAL’s unique drag-and-drop profiling feature on CALgrafix means that a 9500P process controller set up is even quicker and simpler. CALgrafix allows configuration settings to be cloned and written to multiple controllers, reducing valuable time spent programming.  Ian Collins – Product Manager at West Control Solutions says, “When the CAL 9500P temperature controller is used in conjunction with our CALgrafix software it can greatly enhance temperature control, monitoring and recording within complex manufacturing processes and automation systems.”CAL9500-network

It is designed to offer the optimum functionality in a 48 mm x 48mm (1/16th DIN) package so it can be used in almost any application including plastics, packaging, drying and laboratory equipment.

 The CAL 9500P integrated auto tune makes PID control simple and efficient, while the unique dAC function minimises overshoot problems associated with conventional PID controllers giving you greater temperature control.

 The CAL 9500P incorporates a wide range of features including 2 x 4 digit LED display with 2 output LEDs, easy-to-use auto-tuning, simple menu-driven configuration, and IP66 protection to prevent water and dust ingress.

NEMA Rating and IP Code for Enclosure Types

NEMA Rating and IP Code for Enclosure Types

What is NEMA rating or NEMA codes? What does IP20 stand for? What is the difference between NEMA3R and NEMA4?
The below table would help you understand the story.
  • NEMA Rating and IP Code for Enclosure Types

    NEMA Rating and IP Code for Enclosure Types

NEMA stands for National Electrical Manufacturer Association. NEMA ratings are standards that are useful in defining the types of environments in which an electrical enclosure can be used. The NEMA rating system is defined by the National Electrical Manufacturer Association, and frequently signifies a fixed enclosure’s ability to withstand certain environmental conditions.
The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The first IP digit refers to solid objects and the second digit refers to liquids.
The inverter, charge controller or battery enclosures are usually referred with NEMA ratings. The IP code is rarely mentioned, especially for the junction box of solar modules or for indoor electrical devices. There is a NEMA rating table that goes from 1 to 13; however, only some of them are applicable in solar industry.
Here is a table that would help you with NEMA and IP codes:

NEMA IPxx Description
NEMA-1: General Purpose – Indoor IP20: Protection against solid objects up to 12mm. Type 1 enclosures are intended for use indoors, primarily to prevent accidental contact with the enclosed equipment, in areas where unusual service conditions do not exist.
NEMA-3: Dust tight, rain tight and sleet resistant – Outdoor IP64: Total protection against dust and protection against spray or water from every direction Type 3 enclosures are intended for use outdoors, to protect the enclosed equipment against windblown dust and water. They are not sleet (ice) proof.
NEMA-3R: Rainproof and sleet resistant – Outdoor IP22: Protection against solid objects over 12mm and against direct spray up to 15° from vertical. Type 3R enclosures are intended for use outdoors, to protect against rain, and meet the requirements of UL 508 “Rainproof enclosures”. They are not dust, snow nor sleet proof.
NEMA-4: Watertight and dust tight – Indoor and outdoor IP66: Total protection against dust and protection against strong jets of water. Type 4 enclosures are intended for use indoors or outdoors, to protect the enclosed equipment against splashing water, seepage of water, and severe external condensation. They are sleet resistant but not sleet (ice) proof.
NEMA-4X: Watertight and dust tight – Corrosion resistant – Indoor and outdoor IP66: Total protection against dust and protection against strong jets of water. Type 4X enclosures have the same provisions as Type 4 enclosures and, in addition, are corrosion-resistant.
NEMA-12: Industrial use, dust tight and drip tight – Indoor IP55: Protected against dust and protection against low pressure jets of water from every direction. Type 12 enclosures are intended for use indoors, to protect the enclosed equipment against fibres, flyings, lint, dust and dirt, and light splashing, seepage, dripping and external condensation of non-corrosive liquids.

Eagle Signal Timers for Plastics Manufacturing

,

Plastics
You can’t go a single day without encountering literally hundreds, if not thousands, of objects made out of plastic. Since they were popularized for use in consumer packaging and durable goods in the 1950s, plastics have since exploded into a $310 billion a year industry. And behind many those plastic packaging and manufacturing plants are Eagle Signal timers.
For plastics manufacturing techniques such as injection molding machinery, thermoforming and extrusion equipment to blow molding machinery, promoting reliable and safe plastics production and consistent product output is critical. This means reducing unnecessary downtime and eliminating all material waste. The key to accomplishing this is accurate and reliable timing equipment.
Eagle Signal brand electronic timers ensure timed plastic mold release and precise heat and pressure control of the plastic resin pellets within the barrel of the injection mold machine. The on-delay timer activates the heating element which signals the temperature controller to melt the plastic pellets to a given temperature parameter within the barrel for optimum plastic injection or molding at the opposite end.
