Design and Functional Principle
The outputs are potentially isolated from the basic circuit and each
other.
The digital input is double.
S one potential isolated for voltage level
S one not potential isolated for floating contacts
These two inputs are designed as logic OR links.
Installation
The alarm module is pushed in underneath the motherboard into the
module rack up to the stop and connected by the enclosed 8-wire ribbon
cable (5) to the motherboard (see figure 2-10, page 28).
2.5.5 Jy-module
Function
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.
Installation
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 28).
2.5.6 SIA module
The SIA module contains:
S 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.
S 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.
