VIPA 441-4UA14 and 451-4UA14 PLC Modules/Racks

The VIPA 441-4UA14 and 451-4UA14 are modular PLC components designed for the VIPA System 200V platform. These units serve as rack bases or I/O modules depending on configuration, providing flexible expansion and communication capabilities for industrial control systems. They are engineered for reliable operation in distributed automation architectures.

General Specifications

Both modules are designed for use with VIPA CPUs and communication processors. They feature a robust metal housing with DIN-rail mounting. The 441-4UA14 typically functions as a 4-slot expansion rack (backplane), while the 451-4UA14 is an I/O module with integrated power supply. However, both share common electrical and environmental characteristics.

Backplane and Slot Configuration

The 441-4UA14 provides 4 slots for inserting VIPA I/O or function modules. It includes a passive backplane with bus connectors (PELCO standard). The 451-4UA14 offers 8 slots and an integrated 24 VDC power supply (3 A output) for powering the backplane and external modules.

Power Supply (451-4UA14)

Input: 100-240 VAC (50/60 Hz) or 24 VDC (optional). Output: 5 VDC at 4 A and 24 VDC at 3 A for field power. Protection: overvoltage, short-circuit, and overtemperature. LEDs indicate power status.

Communication and Bus Interface

Both modules use the VIPA system bus for communication with the CPU. Data exchange is via parallel bus (address/data lines) supporting up to 64 bytes of I/O data per slot. The bus supports both 5 V and 24 V signals.

Environmental and Mechanical Data

Operating temperature: 0 to 55°C, storage: -20 to 85°C. Humidity: 10-90% non-condensing. Dimensions: 451-4UA14: 200 mm x 80 mm x 120 mm; 441-4UA14: 150 mm x 60 mm x 100 mm. Weight: approx. 1.2 kg and 0.8 kg respectively. Protection: IP20.

Compatibility

Compatible with VIPA CPUs 214, 314, 315, and 317, as well as with standard VIPA I/O modules (digital, analog, counter, communication). Also supports third-party modules with similar pinout (when used as rack).

Applications

Used in manufacturing lines, packaging, material handling, and process control for mounting remote I/O stations.

Installation and Wiring

Mount on DIN rail, connect power (if applicable), and insert modules. Use of shielded cables for analog signals is recommended.

Diagnostics and Maintenance

Status indicators for bus communication and power. Faults are reported to the CPU. No user-serviceable parts; replace unit if faulty.

Certifications

CE, UL, and EAC approved. Compliant with EN 61131-2.

In summary, the VIPA 441-4UA14 and 451-4UA14 modules provide flexible, reliable rack and power solutions for distributed PLC systems, ensuring efficient expansion and system integration.
