Long specification |
Ex isolating switch amplifiers for Namur sensors, 2 channels Secure isolation EN 61010, 4-way isolation up to 2.6 kV AC/DC of all circuits against each other |
Short specification |
Ex isolating switch amplifiers for Namur sensors, 2 channels 2-channel isolating switch amplifiers in 22.5 mm width with an external power supply, to transmit and isolate Namur sensor signals from Ex zones 0,1, 2 into the safe zone. On the output side there is an NPN switching transistor per channel and a common alarm contact (relay/"a" contact) for status or error messages. The component can be configured using standard FDT/DTM software. |
