87WF01E ABB GJR2372600R1515 Control Room Coupling Module

Application:
The module serves to couple control modules to the control
room. It is used whenever the push ---button commands to the
control modules or lamp signals from control modules are
transferred via the bus.
The module incorporates four function units with three pushbutton inputs and three lamp outputs each. Two function units
can in each case be interconnected. Such a combination enables the module to communicate with control modules having
four pushbutton inputs and four lamp outputs.
Pushbutton commands and lamp testing can be released either jointly for all function units through hardware inputs or
separately for each function unit through the bus.
By altering a plug ---in jumper each module output can be individually changed over from lamp operation to LED operation
(see “Annunciation functions”).
Features:
The module may be plugged into any multi ---purpose processing station of the PROCONTROL bus system. It incorporates a
standard interface to the PROCONTROL station bus.
The module checks telegrams received through the station
bus for error ---free transfer on the basis of their parity bits. The
telegrams sent by the module to the station bus are assigned
parity bits to ensure error ---free transfer.
For communication with the operator’s console, the module requires the following voltage:
US Operating voltage +24 V
Split internally into the power supply for
US12 pushbuttons of function units 1 and 2
US34 pushbuttons of function units 3 and 4
The operating voltage US and the lamp outputs are related to
the reference conductor Z.
The operating voltage UD+ is related to the reference conductor ZD.
The operating voltages US12 and US34 are short ---circuit ---
proof with typically 100 mA at 24 V and therefore require no
separate fuses.
The lamp or LED outputs are short ---circuit ---proof and are free
from interaction.
The following malfunctions are indicated on the front of the
module by light ---emitting diodes:
--- Module disturbance (ST)
--- Loss of the voltage US12
--- Loss of the voltage US34
