The Series 9170
Ex i switching repeaters are used to operate contacts, NAMUR proximity
switches and optocouplers. Models are available with one or two
channels. The intrinsically safe digital input is always galvanically
separated from the output and auxiliary power. The channels in the
two-channel devices are galvanically separated. Certain variants transmit
frequencies of up to 10 kHz, and the output signal can be inverted. |
