R. STAHL 9170/21-10-11S Switching Repeater
The 9170 series Ex i switching repeaters can be used for operating contacts, NAMUR proximity sensors or optocouplers. [cite: 1] Models are available with one or two channels. [cite: 2] The intrinsically safe digital input is always galvanically separated from the output and auxiliary power. [cite: 2] The channels in the two-channel devices are galvanically separated. [cite: 3] Certain variants transmit frequencies of up to 10 kHz and the output signal can be inverted. [cite: 4]
