New mini-PLCs provide powerful capabilities in a best-fit package

RS Components has just 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 µVision software suite. All PLCs exhibit 10 I/O and a CAN interface that allows communication with external devices. The STG-800 offers three 0VDC to 30VDC analogue inputs with a 12-bit ADC, a 25KHz-input event counter, a 40µs-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. The mini-PLCs provide hardware-oriented microcontroller programming at the lowest current consumption in a small form factor and are ideal 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.
