The I/O unit VAM 3L/VAM3LX
/VAM3LX
/VAM3LX
/VAM3LX serves as link between the
system’s fibre sensors and the central unit. Each I/O unit has
connections for three arc sensors, one pin sensor and one trip
output.

DA is activated by strong light. The sensor
transforms the light information into the current signal, which
is forwarded through the I/O unit to the central unit. The arc

The pin sensor VA 1 DP
The pin sensor VA 1 DP has the same functions as an arc
sensor but can be temporarily connected to an I/O unit. The
sensor can be fixed to the breast pocket of a technician to
improve safety when working with live switchgear.
