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. These new products and others from the Barth range can be found exclusively on the RS website at uk.rs-online.com/web/b/barth.
