The Pixsys PL110 is a mini DIN rail on-board PLC designed to deliver powerful sequential control, data processing, and analog variable management in a compact footprint. Measuring just 108x90x64mm and mounting easily on a standard EN50022 DIN rail, the PL110 is ideal for space-constrained control panels in industrial automation and building management systems. Its extractable terminal blocks simplify wiring and maintenance, while the optional OLED display provides convenient on-device status monitoring of I/O points and program variables.

The PL110 offers an exceptionally versatile I/O configuration for its size. It includes 8 PNP digital inputs, 8 relay outputs rated at 2A for resistive loads (250Vac/30Vdc), and a comprehensive set of analog inputs. The analog section supports 0-10V and 0/4-20mA signals with 1024-point (10-bit) resolution, two independent NTC-10K thermistor inputs covering -40°C to +125°C with ±0.5°C accuracy, and a dedicated 0-10V analog output with 8-bit (256-point) resolution. The analog output features built-in PID control with selectable P, PI, and PD algorithms, making the PL110 suitable for closed-loop process control applications such as temperature regulation, pressure control, and flow management. Two bidirectional encoder inputs (15kHz each, or 25kHz for a single encoder) are overlaid on four of the digital inputs for motion and positioning tasks. The I/O count can be further expanded using MCM260 expansion modules.

Communication and programming are handled through a robust set of interfaces. Two RS485 multipoint serial ports support the Modbus RTU protocol in both Master and Slave modes, with baud rates up to 57.6 kbps. The serial ports are galvanically isolated from the power supply and inputs, providing reliable communication in noisy industrial environments. A USB type B port enables direct connection to a PC for programming. The PL110 is programmed using PLprog, a ladder diagram software environment structured around easy-to-use function blocks. The programming resources include 128 marker relays, 32 bistable elements, 64 16-bit timers, 16 up-down counters, mathematical and logic functions, range rescaling, and bit-level contact operations. Two timed interrupts with a minimum period of 1 millisecond are available for time-critical tasks.

Under the hood, the PL110 is equipped with 64KB of Flash memory for program storage, 350 words of retentive RAM with a 6-month battery backup, 1000 words of EEPROM, and an internal MMC providing 13,000 words of data storage. A real-time clock with backup battery ensures accurate time-keeping for scheduled operations and event logging. The minimum scan cycle is 2 milliseconds, providing responsive control for most industrial applications. The device operates on a 24Vac/Vdc supply (±15%) with a maximum power consumption of 6W, and is rated for operation in ambient temperatures from 0°C to 45°C with humidity up to 95% non-condensing. The PL110 carries CE marking and complies with EN 61000-6-2 and EN 61000-6-4 EMC standards for industrial environments.

The Pixsys PL110 is an ideal solution for small to medium-sized automation tasks requiring a blend of digital logic and analog process control. Typical applications include temperature and humidity control in HVAC systems, pump and valve sequencing in water treatment, conveyor and material handling systems, and general machine automation where space is limited but functionality cannot be compromised.
