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.

Description

- VFT modem with wide bandwidth (300-22000 Hz)

- Point-to-point coverage up to 20 km and multipoint lines up to 10 km with 0.8 mm cable diameter

- Duplex operation via 4-wire connection, half-duplex operation via 2/4-wire connection

- Point-to-point, point-to-multipoint and multipoint topologies for up to 10 remote stations

- Baud rate of 9600 baud

- Configurable via DIP switches on the front of the unit

- Serial data signalling is completely transparent and requires no parameterisation

- Simple, space-saving DIN rail mounting

- Supply voltage: 24.... . 60 V DC ±20

- Functionally compatible with 23WT24 plug-in modules

Ethernet communication

Application example - mesh copper/optical fibre ring

Description

- Thanks to the ring structure and support for the Rapid Spanning Tree Protocol (RSTP), communication is ensured at all sites even if part of the circuit is interrupted.

- In this arrangement, the secondary ring supports the communication of the primary ring even if part of the primary ring is interrupted.

- The 560NMS24/500NMD02 with two DSL interfaces must be used for sites with two copper lines.

- For sites with copper and fibre connections, the 560NMS24 and 560NUS12 must be used as optical/electrical media converters.

The 560NMD11 DIN rail is also available.

- For stations with two fibre optic connections, the 560NMS24 and 560NUS12 must be used as optical/electrical media converters.

- In addition, an Ethernet modem (Tetra, LTE, etc.) can be connected via the 560NMSxx/5x0NMDxx as (additional) alternative routing.

- With the 560NMS24. a line-through connection can be made automatically in the event of a station blackout. This means that other unaffected nodes/stations can still be accessed.

- Separate VLAN tunnels with bandwidth allocation and prioritisation (QoS) can be assigned to devices.

Another VPN tunnel can be assigned to the managed device for remote configuration and transmission of status information.

The VPN tunnel can be assigned to the managed switch. Alternatively, status information of the managed switch can be transferred to the control system via IEC 60870-5-104/-101.

- Possibility of serial device tunnelling.
