0J-0P3167CC Schneider Universal Input/Digital Output (I/O) Module

Description

0J-0P3167CC Schneider Universal Input/Digital Output (I/O) Module

Product Dimensions：

The TAC Xenta 421A is a Universal Input/Digital Output (I/O) Module within the TAC Xenta family of products, typically used in Building Management Systems (BMS) and HVAC control.

• Function: It serves as an expansion module for TAC Xenta controllers, connecting to the main controller via the LonWorks (or LON) network.

• Design: It is designed to extend the I/O capacity of Xenta controllers (like the Xenta 301, 302, or 401).

• Configuration: The module is configured and managed from a specific controller using the TAC Menta graphical engineering tool. It can also be used as a standalone LonWorks node.

⚙️ Product Parameters (Specifications)

⭐ Product Advantages

• Flexibility: The Universal Inputs are a key advantage, allowing the module to interface with a wide variety of field devices (switches, temperature sensors, pressure transducers, etc.) without needing multiple specialized I/O types.

• Scalability: It easily extends the I/O capacity of Xenta controllers, enabling the control system to handle more physical devices and points.

• Integration: Seamless integration within the Schneider Electric / TAC Xenta / EcoStruxure Building Operation environment via the LonWorks network.

• Reliable Control: The relay outputs provide robust on/off control for heavy-duty field equipment.

⚠️ Precautions (Important Notes for Installation/Use)

• Proper Configuration: The module must be correctly associated and configured with a specific Xenta controller using the TAC Menta tool, especially when used as an expansion module.

• Power Supply: Ensure the 24 VAC power supply is within the specified $pm 10%$ tolerance.

• Wiring: Adhere to maximum wire lengths and appropriate gauges for inputs and outputs (e.g., $660text{ ft}$ max for $22text{ AWG}$ DI).

• Smoke Control Systems: If used in a UL-listed smoke control system application (common for some Xenta modules), specific installation rules must be strictly followed, such as placing the module within $20text{ ft}$ of the Fire Alarm Panel (FAP) and using conduit for connections.

• Output Limits: Do not exceed the maximum control voltage ($230text{ VAC}$) or current ($2text{ A}$) for the relay outputs.

🏢 Product Application

The TAC Xenta 421A is widely used in commercial and institutional buildings for:

1. HVAC Control:

   • Reading temperature sensors (thermistor inputs) in zones and ducts.

   • Monitoring fan status (digital inputs).

   • Controlling small motors, pumps, and damper actuators (digital relay outputs).

2. General Building Automation:

   • Monitoring the status of doors, windows, and security contacts.

   • Receiving alarm signals from other building systems, such as a Fire Alarm Panel (FAP) via contact closures (digital inputs).

   • Lighting control (on/off switching via digital relay outputs).

3. I/O Expansion: Used to provide additional physical points to a Xenta controller that has reached its maximum I/O limit.
