3.6.4 ANALOGUE FLEXIBLE INPUT
An additional flexible analogue input is provided and can be configured as Digital or Resistive.
3.6.4.1 FLEXIBLE SENSOR AS DIGITAL
Arrangement Contact between input terminal and battery negative
Low level threshold 2.1 V minimum
High level threshold 6.6 V maximum
Max input voltage +60 V DC with respect to battery negative
Min input voltage -24 V DC with respect to battery negative
Contact wetting current 7 mA typical
Open circuit voltage 12 V typical
3.6.4.2 FLEXIBLE SENSOR AS RESISTIVE
Arrangement Differential resistance measurement input with individual common
terminals for each sensor input
Measurement current 9.3 mA typical
Full scale
480 Ω
Sensor fail Values greater than full scale return an over range sentinel that may be
interpreted as sensor fail if appropriate (host controller dependant)
Resolution 1% of full scale
Accuracy ±-2 % of full scale resistance, excluding transducer (sensor) error
Maximum common
mode voltage
3 V
Transducer
(sensor type)
Configurable in host controller
Use with contacts Inputs may be used with a contact to ground providing the corresponding
common terminal is grounded. (ie can be used as digital inputs if correctly
configured in the host controller)
3.6.4.3 FLEXIBLE SENSOR AS 0-10V
A future firmware update to the controller will enable this feature. Check with DSE Technical Support
for further details.
3.6.4.4 FLEXIBLE SENSOR AS 4-20MA
A future firmware update to the controller will enable this feature. Check with DSE Technical Support
for further details.
