JUMO TYA S201 Single-Phase Thyristor Power Controller

Name: JUMO TYA S201 Single-Phase Power Controller | Seven Star LLC
Brand: JUMO
SKU: TYA S201

Description

Single-phase thyristor power controller with LCD, 20 A to 250 A

The JUMO TYA S201 (type 709065) is the slim version of the TYA 201 power controller for resistive and inductive loads. A microprocessor controls the unit, and all parameters appear on an LCD with background lighting, with a plain-text menu in the national language and four keys at the front. Typical uses named by the manufacturer include industrial furnace construction and plastics processing.

The controller contains two anti-parallel thyristors, an insulated heat sink and the control electronics, and every unit is fitted with a semiconductor fuse. Devices up to 50 A can be clipped on a 35 mm mounting rail or fitted on a wall plate, while larger devices are for wall mounting only.

In burst-firing mode the phase angle of the first half-wave can be cut, so transformer loads can also be operated. A soft start slowly reaches the set phase angle starting at 180 degrees to avoid high starting or inrush currents, and a dual energy management feature optimizes the load on the network.

Because the load current range starts at 20 A and reaches 250 A, one family covers small ovens as well as large heating banks. Mains voltages of 230, 400, 460 and 500 V are available, and the control electronics take their supply from the same mains connection.

Choosing the version

The order code runs: basic type 709065, version (8 standard with default settings or 9 customer-specific), device language (01 German, 02 English, 03 French, 14 Spanish), load current, partial load failure monitoring (00 none, 01 monitoring), mains voltage and interface (00 none, 54 RS485/422, 63 PROFINET). An example is 709065/8-01-100-01-400-00.

Select the load current with a margin and check the derating curve in the data sheet for ambient temperature and site altitude, because the ampacity decreases above 1000 m installation height. Power loss can be estimated with the empirical formula given in the sheet.

Accessories include the setup program for 709065 and 709066 (part 00544869), a USB cable (00506252), DIN rail installation kits for 20, 32 and 50 A, and matching semiconductor fuses, for example 709710/02 in several ratings up to 550 A.

Electrical connection differs by size. Up to the 20 A type, control and load leads are connected through screw terminals. From the 32 A type, control cables use screw terminals while load leads use cable lugs according to DIN 46235 and DIN 46234 or tubular cable lugs. Creepage distances to SELV circuits are 8 mm for the 20 A type and 12.7 mm from 32 A.

The control section can be configured through the USB interface even without a supply voltage, because the USB port supplies power, and the setup data can be transmitted in that state. This makes it easy to prepare a replacement unit on the bench.

Applications and operation

Setpoint specification can come from a standard signal or the interface. In continuous mode the controller supplies the load continuously according to the setpoint, and in logic mode it behaves like a solid-state relay, switching at the midpoint of the signal range, for example at 12 mA on a 4 to 20 mA signal.

The load monitoring function with Teach-In detects partial load failure and load short circuit, and an integrated diagnostic system reports faults. The control section must stay connected to the mains when a fieldbus is used, so that communication is maintained.

The device is a built-in device according to EN 50178 with pollution degree 2 and overvoltage category III, protection class I, and it must be grounded according to the regulations of the energy supplier. When a bus system is used, the control section remains energized through S1 and the load is switched through S2, with the inhibit input used first for transformer loads or loads with a high temperature coefficient.

About brand

JUMO is the German maker of temperature sensors, process controllers, pressure transmitters and liquid analysis instruments. Moritz Kurt Juchheim founded it in Fulda in 1948 as M. K. Juchheim KG, making glass thermometers with six employees. The name JUMO comes from the founder's name. It is still a family company headquartered in Fulda, and the parent company has been called JUMO GmbH & Co. KG since 2003.

Seven Star LLC is an independent supplier in Muscat. We list JUMO RTD and thermocouple probes, thermowells, transmitters, controllers, recorders and water analysis instruments, and supply them to process plants, OEMs, HVAC contractors and water utilities in Oman and the GCC by type number.

Choosing a temperature sensor starts with the range and accuracy. A Pt100 RTD is accurate and stable from about -200 to 600 °C and is the usual choice in process plants. A thermocouple (type K or J, for example) covers much higher temperatures and responds faster but is less accurate. The wiring also matters: a 3-wire or 4-wire Pt100 connection cancels the resistance of the cable, while a 2-wire connection adds an error that grows with cable length. That is why a head-mounted transmitter is often fitted close to the sensor.

Where JUMO products are used

In Oman and the GCC, JUMO sensors and controllers are used in oil and gas and chemical plants, food and beverage production, plastics and metal heat treatment, HVAC and district cooling, water and wastewater treatment, swimming pools and marine applications.

Ordering JUMO products: what we need

Send the JUMO type number and the full order code from the label (for example 902020/10-...). For probes, add the sensor type (Pt100, Pt1000, type K or J), the number of wires, the insertion length and diameter, and the process connection. For controllers, add the input, outputs and supply voltage.
