The speed (tachometer) input accepts signals from a variety of speed sensors,

including systems based on proximity probes, magnetic pulse pickup sensors, or TTL signals.

Fractional tachometer ratios are also supported.

Configurations can be expressed in metric or imperial units.

Alarm and hazard setpoints are fully programmable Alarm time delay, hysteresis and latching,

hysteresis and latching. Alarm and hazard levels can also be adjusted based on speed or any external information.

The alarm and hazard levels can also be adjusted based on speed or any external information.

Each alarm level has an internal digital output (on the appropriate IOC4T I/O card).

These alarm signals can drive the four local relays on the IOC4T card,

and/or relays on optional relay cards such as the RLC16 or IRC4 via the VM600 rack’s raw bus or open collector (OC) bus.
