TVR Instrumentsvisit website

 

TVR Instruments is announcing an addition to its Ziehl industrie elektronik range of temperature protection relays with new models designated TR640IP and TR660IP. These two new temperature measuring and monitoring relays offer inputs for up to 6 sensors either 6 x Pt 100, Pt 1000, or PTC thermistors. Different sensors can be connected at the same time, for example Pt 100 (RTD) and PTC thermistors.

The TR640IP has 4 limit relays and remote monitoring via TCP/IP connectivity, whilst the TR660IP has 7 limit relays, remote monitoring via TCP/IP LAN and the option of 4 analogue outputs programmable 2 × 0/4-20mA and 2 × 0/2-10V or RS485 RTU. Typical applications cited by TVR are the monitoring of motors, generators or transformers. Other potential applications include the use as a 2 or more step controller with additional monitoring of over or under-temperature, or the monitoring of the differences in temperature of 2 sensors.

Designed for DIN rail mounting, they add to the range of panel and rail mounting temperature protection devices which Ziehl manufacture. Ziehl’s electronic devices for industrial systems are made in Germany, where the company’s operations are certified in accordance with both ISO 9001:2015 and ATEX directive 2014/34/EU.
