Wolf Gateway
Modular Linux Controller PlatformModular Linux-based industrial controller platform. Pick the expansion card that matches your project — same hardware base, different I/O, same software.
Pick Your Expansion Card
Four hardware variants share the same Linux motherboard. Choose based on your I/O requirements.
Wolf-3Oi3Ro
3× Relay (5A @ 230V) 3 Opto-Iso DI RS-485
3 Omron relays + 3 opto-isolated digital inputs. For VPP curtailment, equipment on/off, and bridging signals between separate systems.
Wolf-8ADio1Ro
8 Multifunction I/O 1× Relay RS-485
8 multifunction I/O ports + 1 relay. For sensors, HVAC, mixed-signal automation.
Wolf-2RS485
2× RS-485 Independent baud
2 independent RS-485 ports. For multi-device Modbus and protocol bridging.
Wolf-2DALI
2× DALI-2 buses Integrated bus power RS-485
2 independent DALI-2 buses with on-board bus power. Commission fixtures, run scenes, groups, and emergency-lighting tests. For smart lighting.
