Schneider TAC Xenta 421A Universal Inputs & Relay Output Module, 0-073-0245-0

Universal I/O module with multi-mode analog/digital inputs and relay outputs for TAC building automation systems

Overview

This is a Schneider TAC Xenta 421A Universal Inputs & Relay Output Module, Part No. 0-073-0245-0, an I/O expansion module for TAC building automation systems. It provides four highly flexible universal inputs — individually configurable as digital, thermistor, current, or voltage inputs — alongside five relay outputs, allowing a wide range of field sensors and control devices to be integrated into a single module.

Key Features

  • Four universal inputs (U1-U4): 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.
  • Five relay outputs (K1-K5): Rated for up to 2A at 250V AC, suited to switching a variety of field devices.
  • Flexible AC or DC power supply: Accepts 24V AC ±20% (50/60Hz) or 21.6-40V DC.
  • Low power consumption: Maximum 4W power consumption, with an 8 VA recommended transformer sizing.

As voltage inputs: Input signal 0-10 V DC; input resistance greater than 100 kohm; inaccuracy within ±(7 mV + 0.2% of reading).

LED digital input status indicators: Color red or green (selected using TAC Menta); polarity non-inverted or inverted (selected using TAC Menta) — TAC Xenta 422A only.

Digital outputs (K1-K5): Control voltage, relay outputs, max. 2A at 250 V AC; control current to be protected by a max. 10A fuse, max. 2A (greater current permitted for short periods).

Pulse length: Min. 0.5 s.

Compatibility & Applications

This module is designed for use within Schneider TAC Xenta building automation systems, where its universal inputs allow integration of digital contacts, thermistor sensors, and standard current or voltage signals alongside relay-controlled outputs 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.
