Schneider Electric TAC Xenta 451A Universal Input & Analog Output Module (Lot of 2)

8-point universal input module with multi-mode analog/digital inputs for TAC building automation systems

Overview

This listing is for a lot of two Schneider Electric TAC Xenta 451A Universal Input and Analog Output Modules, I/O expansion modules for TAC building automation systems. Each module provides eight highly flexible universal inputs — individually configurable as digital, thermistor, current, or voltage inputs — allowing a wide range of field sensors to be integrated into a single module. This listing is priced per lot of 2 units.

Key Features

  • Eight universal inputs (U1-U8): Each input can be individually configured as a digital, thermistor, current (0-20mA), or voltage (0-10V DC) input, with 12-bit A/D resolution.
  • Dual thermistor curve support: Compatible with either a 1800 ohm or 10 kohm TAC thermistor sensor, individually selectable, covering a -50°C to +150°C measuring range.
  • Built-in transmitter power supply: Provides 20V DC/25mA power for one 2-wire 4-20mA transmitter, simplifying integration of loop-powered sensors.
  • Flexible AC or DC power supply: Accepts 24V AC ±20% (50/60Hz) or 21.6-40V DC.
  • Low power consumption: Maximum 3W power consumption, with a 6 VA recommended transformer sizing.
  • Sold as a lot of two: Two identical modules included, useful for equipping multiple I/O points or stocking spares.

Technical Specifications

Product type: Xenta 451A, universal input & analog output module.

Supply voltage (G, G0): 24 V AC ±20%, 50/60 Hz, or 21.6-40 V DC.

Power consumption: Max. 3 W.

Transformer sizing: 6 VA.

Universal inputs (U1-U8): Quantity 8; 12-bit A/D resolution.

As digital inputs: Voltage across open contact 20 V DC; current through closed contact 3 mA; minimum pulse input duration 80 ms (TAC Menta CNT block).

As thermistor inputs: TAC thermistor sensor of 1800 ohms at 25°C/77°F (1V DC supply) or, individually selectable, 10 kohms at 25°C/77°F (5V DC supply); measuring range -50°C to +150°C (-58°F to 302°F).

As current inputs: Input signal 0-20 mA (terminals U-M, over-current protected); input resistance 47 ohm; inaccuracy within ±(7 mV + 0.4% of reading); built-in power supply of 20 V DC/25 mA for one 2-wire 4-20mA transmitter.

As voltage inputs: Input signal 0-10 V DC; input resistance greater than 100 kohm.

Compatibility & Applications

These modules are designed for use within Schneider TAC Xenta building automation systems, where their universal inputs allow integration of digital contacts, thermistor sensors, and standard current or voltage signals for HVAC and building control applications. Buyers should confirm compatibility with their existing TAC Xenta controller network and verify the power supply (AC or DC) matches their installation before use.
