WRX900 Wireless Temperature Reciever for WTX700

Brand: Status Instruments

The WRX900 receiver is used together with the WTX700 in head temperature transmitter for wireless temperature measurement. 

The product converts the measured temperature values received into isolated current or voltage signals (0 (4)-20) mA, (0-10 V) as well as making them available via a digital RS485 interface. 

The WRX900 will accept wireless signals from up to 16 WTX700 in head transmitters. 

Any one of the temperature values received can be linked to any one of the Analog or relay outputs and all are available via the RS485 digital interface. 

The product operates using the ISM (Industrial Scientific and Medical) band of 868.4 MHz. This frequency is virtually insensitive to external interferences and allows transmission even in a harsh industrial environment. 

The antenna screws into the top of the DIN rail module but for use in cabinets or to gain a better signal, we also offer an antenna extension lead together with an antenna mounting bracket. 

Programming is possible by using the Wireless configuration kit. 

Alternatively it is possible to programme the product manually using the push buttons and information on the LCD screen.
