TX-I/O Product Range Overview
TX-I/O
™ is a range of I/O modules, with associated power and communication
modules, for use within the APOGEE System. The I/O modules communicate between
the PXC Modular or the PXC-36 and the related devices in the building services plant.
The TX-I/O product range includes the following:
● Eight types of I/O modules, which act as signal converters.
● TX-I/O Power Supply for the TX-I/O modules.
● TX-I/O Bus Connection Module, which bridges communication and power from one
DIN rail to another.
● TX-I/O Island Bus Expansion (IBE) module, which increases the distance between
the primary field panel and expansion field panels on the island bus.
● P1 Bus Interface Module (BIM), which connects TX-I/O modules to the P1 FLN.
The P1 BIM provides power for TX-I/O modules, but it does not contain
applications or perform control; the control database for the TX-I/O points resides
in a field panel.
TX-I/O Module Overview
TX-I/O Modules are modular expansion I/O consisting of an electronics module and a
terminal base; they receive power from a TX-I/O Power Supply, Bus Connection
Module, or P1 BIM.
● The electronics module performs A/D or D/A conversion, signal processing, point
monitoring, and command output.
● The terminal base provides for termination of field wiring and connection of the
self-forming TX-I/O island bus.
All TX-I/O modules provide the following features:
● DIN rail mounting.
● High density point count (compared to physical dimensions).
● Hardware addressed with address keys.
The design of the TX-I/O Modules provides optimum diagnostics and results in a more
efficient installation and maintenance workflow.
● Field wiring may be terminated prior to installation of electronics.
● Connected peripheral devices can be measured without affecting or being affected
by the I/O module.
● Hot-swappable electronic components allow powered electronics to be
disconnected and replaced without removing terminal wiring or disturbing the self-
forming bus.
