The switching amplifier detects the status of 2- and 3-wire sensors, binary signals and AC/DC voltages und transmit the state to the switching output. The input is protected against polarity reversal and short circuit. The connected sensors can be supplied by the switching amplifier or externally.
The mode of operation and action direction can be switched with DIP switches. The device has an adjustable switch-on delay, a switch-off delay and a wiper function.
The auxiliary power can be supplied via the connection terminals or via the optional In-Rail-Bus connector. The switching status and the device status are indicated by LEDs on the front panel. If the device is operated via the In-Rail-Bus, a common fault message is available on the status line.
