PLCs, Power Supplies & Others

Product Overview

This programmable logic controller provides reliable automation control for medium-scale industrial applications. It executes logic sequences and processes I/O data with consistent performance. The PC 0984 manages discrete and analog signals from various field devices effectively. Its modular design allows users to customize the system with additional I/O modules. This controller offers a cost-effective solution for machine and process control needs.

Technical Specifications

The PC 0984 measures 22.0 cm in width, 14.0 cm in height, and 17.5 cm in depth. It weighs approximately 3.2 kg, including the power supply unit and mounting hardware. This controller operates on an input voltage of 120/240 VAC or 24 VDC nominal. It consumes 60 VA maximum under full load conditions. The unit features 16 discrete inputs and 16 discrete outputs integrated into the base chassis. It includes one RS232 communication port for programming and monitoring access. The onboard memory stores up to 1,000 instruction words for user applications. A lithium battery maintains program retention for approximately 2 years without external power. The controller executes basic logic instructions in 5 ms typical. It provides LED indicators for power, run, and fault status at the front panel.

System Architecture and Expansion

This PLC supports expansion through additional I/O modules connected via a ribbon cable. It accepts up to 32 discrete and 8 analog modules for system growth. The PC 0984 incorporates a real-time clock for time-based control functions. Users can program the unit through a handheld programmer or PC-based software. The controller scans all I/O points sequentially during each program cycle.

Physical and Electrical Parameters

Installation and Setup Procedures

Mount the PC 0984 securely on a flat panel surface or DIN rail inside the control cabinet. Connect the AC or DC power source to the designated input terminals. Wire the discrete inputs from sensors, switches, and pushbuttons to the input terminals. Connect output loads such as relays, solenoids, and indicators to the output terminals. Download the application program through the RS232 port using the programming software. The controller initiates program execution when you place it in the RUN mode.

Typical Applications

This controller serves packaging machines, small conveyor systems, and material handling equipment. It controls batch processing, mixing operations, and filling applications effectively. The PC 0984 also supports HVAC systems and building automation tasks. Its integrated I/O makes it ideal for standalone machine control.
