The PD51 converter is a digital device destined to convert the RS-232 interface into the industrial interface RS-485. It enables the increase of the RS-485 bus range and the number of devices in the network with a RS-485 bus. It ensures the automatic steering of the data flow direction. The RS-232 interface is commonly accepted but since it has a limited range and restricted working possibilities, it is not used in industrial data transmission systems. In almost automation systems and advanced control systems, the RS-485 interface is used because it has not such limitations and utilizes the differential procedure for data transmission, what is its main feature.
The PD51 converter is produced in two versions:
PD51-A – to be assembled on a rail, with opto-isolation,
RS-485/Ethernet converter PD8 type allows master devices to transmit data via a wireless Ethernet network to the devices with RS-232 and RS-485 interface. The converter has three operating modes: Real Port network service, serial bridge service with the UDP protocol, TCP Socket service. In the first and third mode, the switching master device of the system is a PC using Ethernet interface. In the second mode, the converter works with a device with Master function and RS-232 and RS-485 serial interfaces. The converter PD8 to work with Real Port network service requires the installation of a virtual serial port driver on a PC with Microsoft Windows. Thanks to the PD8 type converters, this driver provides the existing master systems, i.e. programs like Lumel Heat and Lumel Process, the ability to transmit data between devices with RS-485 or RS-232 interface using Ethernet network. When used in this way, the converter allows to work with one master computer in the given time. When using PD8 to support Modbus and Lumbus industrial protocols
– its correct interaction with master systems installed on a PC depends on the built-in mechanisms to control time intervals between the received transmission characters.
The N100 meter is a programmable digital instrument designed for the measurement of 3-phase, 3 and 4-wire power network parameters in balanced or unbalanced systems. The measured values are displayed on a two-color LED display. The meter enables control and optimization of the power electronic devices, systems and industrial installations. The meter provides measurement of: RMS of voltage and current, active, reactive and apparent power, active, reactive and apparent energy, power factors, frequency, the harmonics of current and voltage /up to 51st/, THD of voltage and current, averaged active and apparent power P Demand, S Demand, averaged current I Demand /15, 30 or 60 minutes/. Voltages and currents are multiplied by given voltage and current ratios of the measuring transformers. Power and energy indications take into account all programmed ratio values. The value of each measured value can be transmitted to the master system via the RS-485 or Ethernet interface. Three relay outputs signal the overflow of the chosen value, and the pulse output can be used for the consumption check of 3-phase active energy. The programmable analog outputs map the assigned parameter. The pulse input can be used to check the counters with the pulse outputs.
There is a galvanic separation between following units of the meter:
–– supply
–– voltage inputs
–– current inputs
–– RS485 interface
–– Ethernet interface
–– pulse input
–– pulse output OC
–– alarm outputs

Controller RE01 is designed to control temperature. It cooperates directly with resistance-type sensors Pt100, Pt1000 and NTC.
The controller has one output for on-off control and one output for alarm signalling. The on-off control employs the PID or on-off algorithm. For the on-off control, the minimum on and off times for the output may be set.The control output has a changeover contact and allows for the direct control of low-power objects.
An innovative SMART PID algorithm is implemented in the controller.In addition, the controller has a binary input to control the controller’s functionsand an internal sound signalling device.
The RE19 dual loop controller/programmer is destined to control the temperature and other physical quantities, e.g. pressure, humidity, level or flow converted into an electrical signal.
The controller can operate two controlled systems or control two physical quantities in one object, e.g. temperature and humidity or a two-zone furnace.
The controller is available in three versions:
RE19S – for control with fixed set-point, with regard to the so-called soft-start and the possibility to switch the set-point by the logic input,
RE19P – for programmed control, in which the set-point changes in time, acc. to a chosen program – 15 programs with 15 segments in each,
RE19V – for stepper motor control – two control algorythms at choice, with or without a reflexive signal.
The RE22 controller co-operates directly with resistance thermometers (RTD) and thermocouples (TC) or quantity converters into a standard signal. It is destined for temperature control in plastics, food, glass, ceramics, dehydration industries and everywhere when it is necessary to stabilize temperature changes.
The measuring input is universal for resistance thermometers and thermocouple sensors or for linear standard signals. The relay output, with a make-brake configuration ( with NOC or NCC contacts) allows to the direct control of low power objects. The manual control and soft-start are also possible. One can protect the controller against the undesirable change of parameters by means of a password. The auto-tuning function permits to select the PID setting in order to a quick output signal adaptation to object parameters.
