The alarm module is pushed in underneath the motherboard into the
module rack up to the stop and connected by the enclosed 8-wire rib-
bon cable (5) to the motherboard (see figure 2-10, page 27).
2.5.5 Jy-module
With the J
y
-option module, the current actuator position can be output
as a two wire signal J
y
= 4 to 20 mA – potentially isolated from the
standard controller. The dynamic control of the J
y
-module makes it also
error self--reporting.
The J
y
- module is pushed in to the bottom compartment of the module
rack up to the stop and connected by the enclosed 6-wire ribbon cable
(6) to the motherboard (see figure 2-10, page 27).
2.5.6 SIA module
The SIA module contains:
- a digital output for outputting a group fault message (see alarm
module)
The floating digital output is implemented as a self error reporting
semiconductor output.
-
two digital outputs for reporting two mechanically adjustable limit
values (L1, L2) by slot initiators.
These two outputs are electrically independent of the rest of the
electronics.
