At a glance
Wireless relays capture equipment power signals and show up to 32 machines on one HMI, with instant alarms on abnormal status.
Is that machine really off? Are equipment-room patrols eating up your team’s time? This system shows equipment status at a glance. Power signals are captured on licence-free radio bands and relayed wirelessly to an HMI that displays every connected machine in real time. Inspections are faster, history is always available, and alarms trigger the moment something is wrong.
Functions
- Monitors the power on/off status of different machines.
- The display unit logs on/off events and supports alarm settings.
- Verified communication range of 500 m inside a fab (depends on site conditions; extendable with repeaters).
