560FSM11 – VFT Modem with Wide Bandwidth Range

(300-22000 Hz)

Applications

The DIN rail device 560FSM11 is a serial telegram modem that transmits data using the binary frequency keying (FSK) principle at a baud rate of 9600.

The 560FSM11 is functionally compatible with the 23WT24 modem (Rack Plug-In Module) and can be operated as a compatible counterpart.

The module’s Voice Frequency (VF) output can be switched to high impedance, so that up to 10 remote stations can be arranged on multiple plug-in lines.
