TR1200 - Pt 100 Temperature Relay - T224095

12-channel Temperature-Relay for Sensors Pt100 (RTD)

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 sequence

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
