Product description
The ABB PM860 is an AC 800M controller-family processor unit for industrial control and process automation duties. ABB describes the module as a 32-bit single-board computer that directly connects S800-I/O through ModuleBus. The MPC860 microprocessor operates at 48 MHz. Firmware storage comprises 2 MByte flash PROM, while working memory comprises 8 MByte SDRAM. With the same application program, ABB states that the PM860 executes approximately twice as fast as a PM851 or PM856. Up to twelve communication interfaces can be connected through the CEX bus. Two RJ45 Ethernet ports operate at 10 Mbit/s in half-duplex mode according to IEEE 802.3 and 10Base-T. The additional RJ45 serial ports COM3 and COM4 use RS-232C; COM3 supports selectable rates up to 19.200 baud, while COM4 communicates with Control Builder at 9.600 baud. Electrical ModuleBus capacity covers one S800-I/O base cluster with up to twelve units and a total of up to 192 signals. The supply is 24 V DC with an allowed range from 19.2 to 30 V DC. ABB specifies a typical current consumption of 180 mA, IP20 protection and dimensions of 119 × 186 × 135 mm for the PM8xx form factor. Installation is on a horizontal DIN rail with unobstructed ventilation clearances. The PM860K01 package with TP830 and bus terminations weighs 1,100 g. For a safe replacement, check the processor version, TP830 baseplate, firmware level, Control Builder project, Ethernet and serial settings, CEX configuration, ModuleBus expansion and battery backup. General interchangeability with PM860A, PM861 or other PM8xx variants is not assumed.

Manufacturer / EU responsible person
Which interfaces does the ABB PM860 provide?
The processor unit provides two RJ45 Ethernet ports, two serial RS-232C ports, the CEX bus and electrical and optical ModuleBus connectivity for S800-I/O.
What should be checked when replacing a PM860?
Check the processor version, TP830 baseplate, firmware level, Control Builder project, network and serial settings, CEX configuration, ModuleBus expansion and battery backup.
Is there a guarantee?
Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.
Please note that the guarantee only applies when the warranty seal is undamaged.
If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.
Further details are provided in the terms and conditions supplied with your quotation.
How quickly do you dispatch and which shipping options are available?
We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.
Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.
We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.
Which payment methods are available?
Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.
As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.
Can we return items if they were ordered incorrectly?
Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.
Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.
Is there a discount when ordering several items?
For larger order quantities or several items of one type, we can offer individual discounts.
Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.
Do you also purchase industrial spare parts?
Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.
The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
