Relais thermique TR800WEB

The TR800Web can be connected to the internet or an intranet and operated via TCP/IP from a normal PC with a suitable browser. No special software and no special instruction is necessary. The Universal-Relay TR800Web monitors and logs signals from up to 8 inputs. Up to 8 limits (one per input) can be programmed for each of the 4 output-relays. Thus e.g. alarm 1 can be activated when the temperature at a sensor (e.g. Pt100) at input 1 exceeds a limit or when the signal of a transmitter for pressure (e.g. 4-20 mA) at input 5 falls below a limit. It can also send an email when a limit is exceeded and/or when the signals falls short of the limit again. A day/night switchover allows to vary limits depending on daytime. In addition the device has an interface RS485 with the protocols Modbus and ZIEHL-standard.

Applications
The TR800Web is used where one or more of the following features a required:

• measuring of up to 8 analog signals and transmit the data via TCP/IP
• reading of measured values and teleservice via internet/intranet
• signalling of alarms via email when limits are exceeded
• monitoring of filling level (water, gasoil) with ZIEHL filling level probe NS6123-6
• logging of measured values and remote inquiry e.g. for monitoring temperatures at engines and in plants

8 Measuring inputs (every input individually programmable)

• Pt 100, Pt 1000 in 2- or 3-wire connection
• KTY 83 or KTY 84
• Thermocouples type B, E, J, K, L, N, R, S, T
• DC 0-10 V, DC 0/4-20 mA
• Resistance 500 Ohm, resistance 30 kOhm
• Difference of 2 signals

4 Alarms

• 4 relays, potential-free change-over contacts
• Remote switching of relays via Ethernet
• or every alarm separately programmable
  • one limit per input (limit and switching-back-value)
  • second set of values switchable day/night
  • switching-delay and switching-back delay
  • remote operation of relays (on/off) with browser
  • interlocked switching
  • email at alarm
