Universal Card Slots
All card slots within the racks are universal in application therefore Input, Output or
Relay Cards can be inserted into any available slot. Cards are inserted from the front
of the rack and once inserted automatically connect to the customer terminals located
on the rear of the chassis. Locking screws are provided at the top and bottom of each
card to ensure they are firmly seated at all times.
Polarisation Keys
For added security all cards and slots are supplied with polarisation keys to prevent
accidental insertion into the incorrect position within the racks. The polarisation can be
changed but care must be taken to ensure the associated field wiring is disconnected
and re-wired before cards of a different type are inserted into slots previously occupied
by different card types. For example high voltage inputs may have been used on a
socket that it being upgraded for use with low voltage outputs.
System Connections
In larger applications multiple racks can used to form larger systems and common bus
connections between racks are linked via RTK supplied plug in ribbon cables. These
connect to dedicated ribbon sockets located on the rear of each rack and are labelled
ribbon IN and ribbon OUT. The standard ribbon is 1mtr in length but additional length
cables can be supplied at time of order if required.
Customer Connections
Industry standard rising clamp terminal blocks, capable of accepting a maximum of
2.5mm2 cable are provided on the rear of each rack for connection of logic power,
signal power, signal inputs, lamp and relay outputs. Locking screws are provided at
the top and bottom of each terminal block to allow them to be easily removed during
installation, commissioning or fault finding.
Fully Field Configurable
Each channel within the 9000TS System can be configured by the customer using the
RTK supplied software utility and all programming information is stored in non-volatile
memory on individual cards with a minimum of 20 years retention. Full details of the
software and available features are provided via a separate manual.
Print Outs
A dot matrix printer can be directly connected to the P925TS-X Interface Card to
dynamically print the alarms as they occur or the user can choose to disable the print
function for later analysis. 3 tactile pushbuttons located on the face of the Interface
Card allow the user to trigger predefined reports as detailed later in this manual.
