As part of its LB system remote I/O solution, Pepperl+Fuchs offers a 4-channel, universal input/output module with Ex i terminals for use in Zone 2, Class I/Div. 2 explosion-hazardous areas. With this module, users get a highly flexible solution for applications such as operation of pressure transmitters, flow transmitters, differential pressure transmitters, level transmitters, and proportional valves, I/P converters, or local indicators.
Each of the four channels can be independently parameterized and operated as either AI or AO. A combination of analog inputs and outputs is also possible. LEDs indicate the status of each channel. White LEDs show the current operation mode. The LB remote I/O universal input/output modules are hot-swappable, which allows quick and easy module replacement without time-consuming system shutdowns. Automatic download of channel settings to the replacement module saves even more time.
The modules support lead breakage detection and short circuit detection. Galvanic isolation separates the intrinsically safe signals from bus and power.
The new LB/FB PROFINET gateways from Pepperl+Fuchs open the door for IIoT 4.0 applications in process industries.
