1. INTRODUCTION
•
The TPIs 2T is a module of 2 logic inputs, extra narrow (7.2mm) designed
for DIN rail mounting.
•
It belongs necessarily to a local network made up of converters and/or
output modules.
The status of its 2 inputs, as well as the result of a logical «or» or «and»
between its 2 inputs can be associated with the converter or with the output
module to perform several functions (eg.: direct driving of a relay, zero reset
of alarm recording, etc.)
•
Each converter or module is fixed on the DIN rail via a 5 points footing which
allows the communication and the supply of the TPIs of the network (24Vdc
±30%).
Up to 50 TPIs can be connected on the same bus and up to 200 different
measures can be made to transit ; In this configuration the maximum scan-
ning time is 200ms.
•
The programming is performed via the µUSB connector located on the front
face, which is to be connected to a computer of the type PC equipped with
the software SlimSet.
