WAGO‘s 24 VDC Valve Ex i 4-Channel Digital Output Module (750-539) controls both valves and valve terminals from various manufacturers (e.g., Bosch, SMC, Festo, Norgren) in Zones 1/21 and 0/20. This special I/O module version permits a higher output current of about 50 mA, while providing twice the number of channels.
4-Channel Analog Input Module Opens Up New Possibilities
WAGO‘s 750-486 4-Channel Analog Input Module allows transmitter signals to be recorded for the following measurement ranges: 0 … 20 mA and 4 … 20 mA, as well as 3.6 … 21 mA (NAMUR NE43). The four channels can be individually parameterized and offer tremendous flexibility for new applications in the process industry, marine sector or in process engineering.
Both modules are ATEX- and IECEx-certified, making them ready to connect sensors/actuators in hazardous areas of Zones 1/21 and 0/20. Diagnostics are performed channel-by-channel (e.g., short circuit, wire break or out-of-measurement range). Furthermore, the modules‘ compact design saves space in the control cabinet. WAGO‘s two new Ex modules are in stock and ready to ship.
