The unique KD481P graphical program controller in a small size (DIN 1/16) gives you an easy-to-use, reliable solution for time-varying control at an affordable price. (We have been producing program controllers since our company was founded, and we have developed the KD481P based on our years of experience and user needs. Knowing our competitors' products, we can rightly claim to have the smallest program controller with a semi-graphical display. This controller gives each device a unique, easy-to-use programming interface, without the need for special development.)
The large display, which is clearly visible from a distance, shows the measured value and the current status of the program below it.
Operation is very simple with a 
button to scroll through the program. The program step selected on the semi-graphic display 
(green illuminated segment) can be changed even while the program is running, without changing the control.
The necessary configuration adjustments can be made while the system is running, without stopping and restarting.
Adjustments can be made from the front panel and via the computer link.
The configuration menu has a system structure. The selective and sensitive menus provide access only to the settings required for a particular configuration. There are no redundant settings and no settings that do not work. Menu and program settings can be tailored to a wide range of uses. Settings can be protected against unauthorised access.
Small size and "quick-connectors" ensure easy installation. The IP67 protection makes the controller suitable for operation in almost every environment.
Multiple computer connectivity options - RS232, RS485, Ethernet, Wifi and DirectLink with MODBUS communication - guarantee connectivity to process control systems. Our free visHAGA visualisation and configuration software provides a cheap and easy alternative to computer visualisation. The program includes full-featured virtual controllers, which can be used to configure devices and edit programs. Settings can be stored on the computer and restored to the devices at any time.
By linking controllers on a dedicated computer interface (digital remote SP), (dT)-cathode and multi-zone tracking controls can be easily set up.
Size and wiring are compatible with current members of the controller family and with previous devices.
Description
- multiple universal high speed inputs: Pt100, resistance thermometer, thermocouple, standard signal (0/4-20mA, 0/2-10V)
- 2 digital inputs: with predefined functions or freely usable
- max. 7 signal clamp and/or SSD outputs or max. 3 configurable standard signal outputs (0/4-20mA, 0/2-10V)
- full-featured autotuning PID controller for all intervention elements (SSD, Relay, Heat-Cool, motorised-valve, standard signal output, On/Off control with hysteresis), charger-drain valve control, weather tracking control and solar panel control
- Pulse Density Modulation (PDM) intervention for SSD drives, faster and smoother intervention than the common Pulse Width Modulation (PWM).
- Advanced control modes: multi-zone/tracking control, cascade, ΔT-cascade, using digital remote setpoint.
- Available with up to 100 × 8 step programmer with event code management, program splicing, guaranteed thermal hold time
- 8 configurable ALARMs with logic functions, latching, sample and hold operation
- 3 full time relays (timer, counter, delay functions) with direct feedback
- Analogue and digital totalizer, mains power calculation
- off-line data logger with time stamp, programmable sampling with ~132000 stored data
- available with multiple computer connections (RS232, RS485, Ethernet, Wifi, DirectLink), MODBUS communication
- User-friendly system architecture, selective and sensitive menu, quick and easy configuration in a minimum number of steps.
- Easily customisable management and menus for safe operation. Hide unnecessary settings from the operator, password protected.
- Free downloadable computer program and configuration software: visHAGA
- The front panel allows easy programming of the time setpoint program. Program-number selection from front panel, external selector switch and computer. Program-start similarly from front panel, external selector switch or computer. Program can be hidden, protected from unauthorised access.
Applications:
The KD481P controller is suitable for most regulation and simple control tasks. Based on customer feedback, the application possibilities are endless.
Its small size and IP67 (front panel) protection does not limit its use in dusty and wet locations.
The housing is made of Polycarbonate (bulletproof glass), which protects the device against external influences and is flame retardant!
Serial production can be accelerated by the cloning function of the device,
which is able to transfer itself (settings and programs) to another device, minimising the time spent on set-up.
The various uses:
- Laboratory instruments: sterilizers, shredders, dryers, heaters, fermentors
- Food processing machinery: fryers, various ovens, freezers and coolers, tobacco dryers, distillers, brewers, milk and egg pasteurisers, fumigators, dryers, steamers.
- Building services engineering: weather-dependent multi-boiler controls for installations, heat centres, boiler and floor heating controls for houses, solar collector controls, domestic hot water production, air conditioning, condensation control for warehouses, ventilation controls
- livestock farming, plant production: temperature and humidity control, phytotron, heat and humidity control of greenhouses, hatcheries and sheds, pens and sheds.
- Agriculture: heat and humidity control of mushroom farms, crop and seed drying,
- Industry: control of small and large furnaces with multi-channel, cascade or ΔT-cascade control, hardening and tempering equipment, cementing, nitriding, reactors, casting machines
- Special waste incinerators and crematoria, hospital waste disposers
The possibilities go beyond the above mentioned applications.
The systems can operate as stand-alone or networked systems. Computerised monitoring ensures the storage of process data, continuous monitoring improves quality control. Data from an optional built-in off-line data logger can be used to monitor the process afterwards, ensuring real-time reporting of the technology.
The built-in off-line data logging provides enhanced security, as long as the controller is operational, the data logging exists, regardless of the existence of a computer connection.
