Analogue input module for safety controller
February 1st 2008 Pilz has introduced a new
analogue input module for
its PNOZmulti modular safety
controller.
Up to four PNOZ ma1p
modules can be mounted on
the left-hand side of a PNOZ
m1p or PNOZ m2p base unit,
and each module can accept
two analogue inputs.
Depending on the
configuration of the
hardware and safety logic,
the module meets the
requirements of EN IEC
62061 SIL2 or SIL3, as well
as performance level (PL)e
of EN ISO 13849-1.
A wide range of analogue
sensors can be used with the
new module – typically in a
dual redundant
configuration – such as
encoders, temperature
sensors, pressure sensors or
position/level sensors. The
PNOZmulti controller can
then monitor for range limits
or a maximum of eight
threshold levels per input.
Reaction time is just 75ms.
Pilz says that virtually any
safety-related application
requiring monitoring of an
analogue value can benefit
from the new analogue input
module, as it accepts a ±10V
or 0-20mA signal. More articles from Pilz Automation Technology: |
