TX-I/O Product Range

Description

TX-I/O™ is a range of I/O modules, with associated

power and communication modules, for use within the

APOGEE Automation System. The TX-I/O product

range includes the following:

• Eight types of I/O modules, which act as signal

converters. The I/O modules communicate

between the PXC Modular or the PXC-36 and the

related devices in the building services plant.

• 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

bridges communication between the primary field

panel and expansion field panels.

• 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 Modules provide I/O points for APOGEE based

upon TX-I/O Technology. TX-I/O Technology provides

flexibility of point types, tremendous flexibility of signal

types and support for manual operation.

There are eight types of TX-I/O modules:

• 8 point DI module (TXM1.8D)

• 16 point DI module (TXM1.16D)

• 6 point DO with Relay module (TXM1.6R)

• 6 point DO with Relay and Manual Override

module (TXM1.6R-M)

• 8 point Universal module (TXM1.8U)

• 8 point Universal with local override/identification

device (LOID) module

(TXM1.8U-ML)

• 8 point Super Universal module (TXM1.8X)

• 8 point Super Universal with LOID module

(TXM1.8X-ML)

Features • The self-forming TX-I/O island bus transmits power as well as communication signals. − The TX-I/O island bus can be extended a maximum of 164 feet (50 meters). − Adding an Island Bus Expansion (IBE) module expands communication data up to an additional maximum of 200 feet (61 m) in two directions. • Hot-swappable electronic components allow powered electronics to be disconnected and replaced without removing terminal wiring or disturbing the self-forming bus.

• Green LED status per I/O point that varies in intensity according to the voltage and current (directly proportional). Digital input support includes: • TX-I/O Power Supply (TXS1.12F4) Voltage free/dry contacts • Pulse counters up to 25 Hz Analog input sensor support includes: • 1K Nickel – Landis & Gyr curve • 1K Platinum – 375 and 385 coefficient • 10K and 100K Thermistor – Type II Curve Active input and output support includes: • Analog input voltage 0-10 Vdc • Analog output voltage 0-10 Vdc TXM1.

The TX-I/O Bus Connection Module performs the following functions: • Routes CS (+24 Vdc Communication Supply) and CD (Communication Data Signal) between DIN rails. • Provides an input point for 24 Vac to power additional peripheral devices. • Isolates the 24 Vac peripheral device supply in case of overload or short-circuit with Class 2 distribution. The replaceable AC fuse can be accessed from an installed module. • Indicates the AC fuse status (via LED) for easy diagnostics.
