ТР1200 Термални релеј

Temperature relays TR1200 measure the temperature of up to 12 sensors within 199...+850°C and provide the data at an interface RS485 for external evaluation. With its universal power-supply AC/DC 24-240 V it can be connected to all common supply voltages. The TR1200 provides the data as Modbus-RTU-protocol or according to the ZIEHL-standard. With protocol ZIEHL standard it can replace 2 ZIEHL TR600 relays. TR1200 itself does not monitor temperatures for limits. For direct monitoring of temperatures our devices with alarms and output relays are recommended. It is used where temperatures of many sensors Pt100 shall be evaluated by a device with input RS485.

Applications are e.g. monitoring of

• motors and generators (windings, bearings, coolant, ambient temperature)
• transformers (windings, core, ambient temperature)
• machines, plants and equen

Sensors and Displays

• 12 inputs for sensors Pt 100 (RTD)
• Connection 2- or 3-wire
• unneeded inputs can be switched off
• monitoring of sensors for short-circuit an interrupt
• e-digit-display for temperature
• LEDs for assigning the measured value, error, state of relay and interface

Interfaces:

• Interface RS485(protocols ZIEHL standard and modbus RTU)
• Baud rate (4800/9600/19200) and Parity-Bit
• selectable protocols see operating manual on www.ziehl.de
• Relay for error (1 co-contract) for sensor error and operational failure

More features

• easy operation and selection of temperatures at the device
• Sensor-Simulation
• Code protection against manipulation of settings
• Universal supply voltage AC/DC 24…240 V
• Housing for switchgear-mount, 140 mm wide, mounting height 55 mm
• mounting on DIN rail 35 mm or with screws M4 (option)

Software for operation(download from www.ziehl.de)

• software (modbus) for programming the inputs
• Logging function (with connected PC only)
• Hardware for every TR1200: PC with USB or RS232 interface + RS485-USB or RS485-RS232 converter (depending on interface)
• Software: Win7 / Win10, Excel 2010-2016
