Digital Overspeed Protection System with PROFIBUS -DP 振动保护模块

speed sensors are continuously

checked on operating within the

permitted limits.

Moreover, the channels mutually

check and supervise the output

signals of each other. If the internal

fault detection circuit detects an error,

this will be indicated via the output

contacts and shown on the display as

plaintext.

By means of the the PROFIBUS DP

interface the recorded data can be

passed on to host computers.

By using prefabricated connection

cables and screw terminals, the

systems may be integrated

economically in 19“ cabinets.

For the measurement of speed and

for the protection from overspeeds,

epro offers three system variants.

System DOPS

This system offers a maximum in

functionality and is certified

according to SIL3 – DIN EN 61508

in combination with epro MMS

eddy current measuring chains. It

requires the following components:

- 3 x monitor MMS 6350 (/DP)

(incl. firmware applic. no. 0)

Profibus-interface (optional)

or alternatively

- 3 x monitor MMS 6350D (/DP)

(incl. firmware applic. no. 0)

with speed display

Profibus-interface (optional)

In addition:

- 1 x Backplane MMS 6351/00

- 1 x 19“ frame MMS 6352

- 6 x screw terminals MMS 6361

- 6 x cable 0.5 m MMS 6362

alternatively

cable 3 m MMS 6360

- 1 configuration kit MMS 6950

- 3 x blind plate BLE 008, for the

installation of monitors without

display

When using this system line, there

are additional combinations

available via relay outputs beside

the normal outputs of the alarms

OUT1....OUT6 and the system

supervision Channel Clear:

2 v 3 combination output OUT1

2 v 3 combination output OUT2

2 v 3 combination output OUT3

2 v 3 combination Channel Clear
