damage the instrument.
l
Maximum Source Current: 20 mA
l
Overload Protection: 25 mA
Current Outputs (One or Two)
These outputs provide a 21 mA dc maximum into a negative or
positive grounded load or into a non-grounded load. Current
outputs are isolated from each other, line power, earth ground and
all inputs. Outputs can be easily configured via the keyboard for
either direct or reverse action and for either 0 to 20 mA or 4 to 20
mA without field calibration.
Either or both current outputs can be used in an Auxiliary Output
mode. This Auxiliary Output can be configured to represent Input,
PV, Setpoint, Deviation, or Control output. The range of an Auxiliary
Output can be scaled per the range of the selected variable and
can be set anywhere between 0 to 21 mA.
The Second Current Output is mutually exclusive with the second
Digital Input.
l
Resolution: 16 bits over 0 to 21 mA
l
Accuracy: 0.05% of full scale
l
Temperature Stability: 0.01% F.S./°C
l
Load Resistance: 0 to 1000 ohms
Alarm Outputs
(Optional)
One SPDT Electromechanical relay. A second alarm is available if
the second control relay is not used for control purposes.
Up to four setpoints are independently set as high or low alarm,
two for each relay. Setpoint can be on any Input, Process Variable,
Deviation, Manual Mode, Failsafe, PV Rate, RSP Mode,
Communication Shed, or Output. A single adjustable hysteresis of
0.0 to 100.0% is provided. The alarm can also be set as an ON or
OFF event at the beginning of a Setpoint ramp/soak segment.
Alarm Relay Contacts Rating:
Resistive Load: 5 amps at 125 Vac or 250 Vac or 30 Vdc
