Discrete commands
Relay or MOSFET outputs for ON/OFF functions. Output type is selected using the wiring diagram: voltage, load and connection logic matter.
M880.
Commands, radio communication
and integration.
M880 is a family of systems introduced in 2016. It includes push-button and joystick transmitters and receivers with different outputs. M880 identifies a system generation, not a complete configuration.
What sets the models apart.
| Model / series | Controls | Practical difference |
|---|---|---|
| RAY EP | Single-stage buttons | Compact panel for discrete commands. |
| WAVE2 | 6, 8, 10 or 12 two-stage buttons | Stepped commands; DM versions include a feedback display. |
| ZED | Single- or dual-axis joysticks, buttons and selectors | Compact enclosure with a flexible panel layout. |
| ZEUS2 / THOR2 | Joysticks and auxiliary commands | Panels for multifunction machines; display versions available. |
| AXT | Belt-worn push-button transmitter | Designed for forestry winches. |
Earlier WAVE and ZEUS generations must not be equated with WAVE2 and ZEUS2. The generation is identified from the equipment labels and documentation.
Outputs and interfaces.
Proportional control
Depending on the receiver, PWM, current and voltage outputs are available. These provide continuously variable control, for example of electrohydraulic functions, rather than simple on/off switching.
Controller communication
Suitable configurations support CAN Bus, CANopen and RS232/RS485. L and M also offer PROFINET and EtherNet/IP variants. These protocols are family capabilities, not standard equipment on every receiver.
Different sizes.
Different signal counts.
| Receiver | Outputs | Enclosure protection |
|---|---|---|
| S DC | Up to 14 MOSFET and 4 analogue outputs | IP66 |
| L AC / L DC | 16 relays or 20 MOS; up to 8 analogue outputs | IP66 |
| H AC / H DC | Up to 73 relay or MOS and up to 32 analogue outputs | IP66 |
| M AC | 22 relays and 4 analogue outputs | IP20 — installation requires appropriate protection |
Maximum capabilities depend on version and layout. Not all outputs are necessarily available simultaneously in every system. Supply and electrical specifications must be checked in the selected receiver’s documentation.
What needs to be agreed.
Frequency and channel management
M880 offers radio versions in the 433/434 MHz, 868 MHz, 915 MHz and 2.4 GHz bands. A specific version is selected; there is no single universal module for every band.
AFA automatically manages radio channel selection; certain versions offer a fixed channel, LBT or Frequency Hopping. The option depends on the radio module and application conditions.
STOP and operating commands
The series technical data lists PL e, category 4 to ISO 13849-1 for the applicable STOP function. For joystick UMFS commands, it lists PL d, category 3.
These ratings apply to specific functions. They do not assign the same rating to the entire machine: the result depends on circuit integration, system version and the machine risk assessment.
Options with a specific purpose.
Options are not automatically included on every model. Availability is checked for the specific transmitter, receiver and system version.
How to check
that the system fits your application.
- Commands: enough buttons and axes; discrete and proportional functions clearly identified.
- Electrical integration: receiver supply, output types and required controller protocol match.
- Radio version: band, operating mode and compatible transmitter specified.
- Safety: STOP, interlocks and required behaviour documented; machine integration verified.
- Package: batteries, charger, cables, mountings and agreed options listed separately.
Technical basis: IMET M880 catalogue, revision 1.1 (08/2025), and the manufacturer’s technology descriptions. Where revisions differ, documentation for the specific version takes precedence.
