Outputs
4-20mA Outputs
Buffered Outputs
Each output is independently programmed
to represent speed or acceleration, from
either channel.
Two isolated outputs
300 ohm max load
1 active buffer per input channel
Output range configurable by wiring:
-24 to +9V
-5 to +24V
-5 to +9V
Third buffered output available when the
module is configured for single redundant
channel mode. Outputs a CMOS (0 to 5
volts) level square-wave that corresponds
to the active input signal.
Sensor Fault Detection
Eddy Current Transducer
Magnetic Pickups
Bias voltage is compared with the fault
limits.
A current source is available for biasing
passive magnetic pickups to detect open or
short circuits.
