Schneider Electric 007300152 TAC Xenta 302 Programmable Controller

Schneider Electric 007300152 Controller TAC Xenta 302

The Schneider Electric 007300152 is the complete TAC Xenta 302 standalone programmable unitary controller, designed for direct digital control (DDC) of medium-complexity HVAC, auxiliary machinery, and process loops. Built on a two-piece modular architecture, the controller separates the removable electronics processor unit from the fixed field-wiring terminal base. This design lets watchkeeping engineers replace or swap the logic module without disconnecting field sensor cables or actuator wiring.

Operating on 24 V AC or 19–40 V DC, the TAC Xenta 302 executes custom functional block logic programmed via TAC Menta and communicates across an Echelon LONWORKS TP/FT-10 free-topology network at 78 kbps. When network links drop, the controller maintains autonomous closed-loop regulation using its onboard microprocessor and battery-backed real-time clock.

Features

1. Balanced 20-Point Onboard I/O: Combines 12 inputs (4 digital, 4 thermistor, 4 universal) and 8 outputs (4 electromechanical relays, 4 analog 0–10 V DC) for single-unit control of air handlers, chillers, or heat exchangers.
2. Hot-Swappable Two-Piece Construction: All field terminations land on the separate terminal base (0-073-0901), allowing rapid electronics replacement during critical port calls or plant shutdowns without disturbing wiring harnesses.
3. Native LONWORKS TP/FT-10 Networking: Communicates at 78 kbps using Standard Network Variable Types (SNVTs) and explicit LONTALK messaging for peer-to-peer data exchange and SCADA integration.
4. 72-Hour Power Failure Protection: Integrated real-time clock (±12 minutes/year accuracy at +25 °C) and memory backup retain schedules, setpoints, and trend logs during main switchboard blackouts.
5. Transient-Protected Field Inputs: Every input channel complies with EN 50082-1 electromagnetic immunity standards to prevent false trips caused by heavy contactor switching and VFD noise.

Compatibility

• Engineering & Programming Software: TAC Menta (graphical functional block programming and XIF generation) and TAC Vista IV / Engineering Classic / LNS Network management tools.
• Local Operator Interfaces: Compatible with the TAC Xenta OP operator panel, which snaps directly onto the front housing, mounts on a control cabinet door, or connects via modular cable as a handheld service terminal.
• I/O Expansion Modules: Supports up to 2 remote TAC Xenta 400 series I/O modules (such as TAC Xenta 411, 412, 421A, 422A, 451A, 452A) over the LONWORKS TP/FT-10 bus when field point counts exceed 20 I/O.
• Field Sensors & Actuators: Direct compatibility with Schneider Electric / TAC 1.8 kΩ NTC thermistors, 0–10 V DC pressure/humidity transmitters, 0–10 V DC modulating damper/valve actuators, and 24–230 V AC pilot relays.

Frequently Asked Questions

What is the difference between part number 007300152 and 0-073-0011-2?

Part number 007300152 is the complete factory assembly consisting of both the removable TAC Xenta 302 electronics module and the screw-terminal connection base. Part number 0-073-0011-2 (or 0-073-0011) refers strictly to the upper electronics processor unit (TAC Xenta 302/N/P), which snaps onto an existing 0-073-0901 terminal base.

Can the Schneider Electric TAC Xenta 302 run on 24 V DC shipboard or panel power?

Yes. The controller accepts either 24 V AC ±20% (50/60 Hz) or 19–40 V DC across terminals G and G0. Keep in mind that if you use 24 V DC supply power, any external field actuators or sensors sharing that supply must also be rated for DC operation.

Does the TAC Xenta 302 come pre-programmed out of the box?

No. The TAC Xenta 302 is a freely programmable controller rather than a fixed-function thermostat. Before installation, an engineer must upload the custom functional block application using TAC Menta software via the front RS-232 modular port or download it over the LONWORKS network via TAC Vista.

How many expansion I/O modules can be connected to a single TAC Xenta 302?

You can expand a single TAC Xenta 302 with up to 2 remote TAC Xenta 400 series I/O modules over the LONWORKS TP/FT-10 twisted-pair network. Each expansion module is bound exclusively to one host controller.

What temperature sensors are compatible with the B1–B4 and U1–U4 inputs?

The analog thermistor inputs are engineered for TAC 1800 Ω (1.8 kΩ) at 25 °C NTC thermistor sensors, covering a measurement range of -50 °C to +150 °C (-58 °F to +302 °F). If you need to integrate 4–20 mA transmitters, connect an external 500 Ω precision shunt resistor across a 0–10 V DC configured Universal Input (U1–U4) and M.
