Temperature monitoring and remote monitoring From Ziehl Industrie elektronik

Ziehl Industrie elektronik range of temperature protection relays for PTC,  Thermocouple, PT100 or PT1000 continues to grow with the addition of a door mounting kit for several DIN rail mounting units.

The continue technological steps taken by Ziehl are now shown in the TR640IP and TR660IP series of multi input, mixed sensor type relays with remote monitoring via the ethernet as standard.

The two new additions to the Ziehl Industrie elektronik range of temperature measuring and monitoring relays are the TR640IP and the TR660IP. Both units 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, e.g. 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 x 0/4 – 20 mA and 2 x 0/2 – 10 V or RS485 RTU.

Typical applications are monitoring of motors, generators, or transformers. In applications it can be used as a 2- or more step- controller with additional monitoring of over- or under temperature or monitoring of differences in temperatures of 2 sensors. Pre-set programs allow easy setting e.g. monitoring of transformers with/without monitoring of the temperature of core or with/without controlling a ventilator.
