HINE DESIGN R94-1164 PLC Control Box 144760
The HINE DESIGN R94-1164, part number 144760, is an integrated control box containing a programmable logic controller (PLC) and necessary I/O modules. This unit is pre-assembled in a protective steel enclosure, ready for deployment in industrial automation, conveyor systems, and packaging machinery.
Enclosure and Construction
The control box measures approximately 400 mm x 300 mm x 200 mm and is constructed from powder-coated steel with an IP54 rating. This ensures dust resistance and protection against water splashes. The door features a transparent polycarbonate window for status LED viewing and a key-locking mechanism for security. Cable entries are provided via M20 and M25 glands on the bottom panel.
PLC and I/O Configuration
Internally, the unit houses a compact modular PLC with a 24 V DC power supply. The CPU features 32 KB of program memory and supports ladder diagram programming. I/O complement includes 16 digital inputs (24 V DC sink/source), 12 relay outputs (2 A per channel, 250 V AC max), and 4 analog inputs (0–10 V or 4–20 mA selectable). Two RS485 ports allow connection to HMI or SCADA systems via Modbus RTU.
Protection and Reliability Features
Overvoltage and reverse polarity protection are built into the power input. The outputs are short-circuit protected with automatic fuse reset. A backup supercapacitor retains the user program for up to 10 days without external power. The box also includes a removable terminal block for convenient wiring replacement.
Typical Applications
This control box is suited for controlling small to medium-sized machines: conveyor sorting, mixing stations, pump controls, and batch processing. Its rugged design withstands vibrations up to 5 g and ambient temperatures from 0°C to 50°C. Many users install it directly on the machine frame or near the process area.
Installation and Commissioning
Mounting is via four M8 brackets on the back panel. After connecting the main power (AC 110–240 V to the internal power supply) and field devices to the terminal blocks, the user can upload the program via the USB programming port. The pre-installed logic includes basic safety interlocks and emergency stop handling, but custom logic can be downloaded using IEC 61131-3 software.
