06 - Ziehl: Monitors up to six sensors simultaneously
The temperature relays type TR660IP from Ziehl monitor up to six sensors simultaneously for up to seven limit values. Different sensor types, for example PTC thermistors, Pt100, Pt1000 or PTC, can also be connected and evaluated. Applications include the monitoring of motors, generators or transformers. The device is also suitable for use as a 2- or 3-point controller with additional alarms for over/under temperature and as a differential temperature monitor. Numerous preset programs simplify commissioning, for example transformer protection with/without core temperature monitoring and with/without fan control. Operation takes place on the device or with the built-in web server via Ethernet. Temperature differences and the rate at which the temperature rises can be monitored. The temperature curve and history are recorded. The network connection is made via Ethernet TCP/IP and values are queried via Modbus TCP.
