RS Components has updated its mini-PLC range from highly innovative controller manufacturer Barth Elektronik. The new product introductions, for which RS is the exclusive global distributor, include three new mini-PLCs, a new parameter programmer and a touchscreen display.
The three new mini-PLCs are based on a 32-bit ARM Cortex processor, which offers a significant step change in performance. Programming is via the established miCon-L software, as well as allowing open source C-programming with the KEIL uVision software suite. All PLCs exhibit 10 I/O and a CAN interface that allows communication with external devices.
The STG-800 offers three 0 to 30V DC analogue inputs with a 12-bit ADC, a 25KHz-input event counter, a 40us-input pulse and frequency counter, four solid-state power outputs (up to 1.5A) and a 16-bit 1Hz to 25kHz power PWM output. The STG-810 model adds an IrDA (Infrared) comms port, for communication with the new PG-65 parameter programmer. Finally, the STG-820 offers the same as the STG-810, but offers analogue output instead of PWM.
These mini-PLCs provide hardware-oriented microcontroller programming at the lowest current consumption in a small form factor and are well suited for a range of applications, including industrial and building automation, automotive and maritime technology, technical education/university, and white goods. All three PLCs come with connectors and are complemented by open source templates, the miCon-L software suite and manuals and sample programs, which can all be downloaded.
Also at RS, the new PG-65 parameter programmer can be connected via CANbus or IrDA to the PLCs and can be used to activate or deactivate programs or upload new parameters to easily adjust I/O settings without the need for a computer. Its 2.4 inch 240 × 320 colour touchscreen display, rugged design, aluminium die-cast housing and intuitive graphical menu makes it suitable for field service use. The DMA-20 offers the same functionality as the PG-65 parameter programmer, but with an IP65 (splash proof) touchscreen display.
Many industrial controllers are often over-specified, which results in additional expenditure, steeper learning curves and over-complication. The mini-PLC range from Barth on the other hand delivers a best-fit option for a whole range of smaller applications that simply do not require overly powerful PLCs.
