Product description
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.
>Accessory: Installation frame ER8 for panel mount
