Description
The RKI Instruments 9850 Interface wireless receiver is capable of monitoring all 255 wireless addresses and converting the signals to a RS-232 or RS-485 Modbus output. Designed to be used in conjunction with an existing PLC, computer or SCADA system currently in place. Other digital outputs include Ethernet-to-Website and USB Virtual COM PORT. If analog output is required, an optional Analog Card is available and provides a 4-20mA output for up to 32 wireless sensors.
The AirLink 9850 Interface Wireless Receiver represents the latest leading edge wireless technology in fixed gas detection today.
