Description
1-channel, Input Ex ia, Mounting in Zone 2, Class I/Div.2 or in the safe area, Input for frequency, counter, direction of rotationpa. The device accepts digital input signals of NAMUR sensors or mechanical contacts from the hazardous area. Open and short-circuit line faults are detected. The intrinsically safe input is galvanically isolated from the bus and the power supply.
