Specifications
Resistive Load: 5 amps @ 120 Vac or 240 Vac or 30 Vdc
Inductive Load (cosj = 0.4): 3 amps @ 130 Vac or 250 Vac
Inductive Load (L/R = 7 msec): 3.5 amps @ 30 Vdc
Motor: 1/6 H.P.
NOTE: Applying an external power supply to this output
is damages the instrument.
Maximum Sink Current: 20 mA
Short-circuit current limit: 100 mA
Open Collector Outputs (One or Two)
Socketed assembly replacing a relay. Two types of loads are
supported, resistive load and pilot duty load. Opto-isolated
from all other circuits except current output and not from
each other. Internally powered @ 28 Vdc (0 mA) ~ 24 Vdc (20
mA).
NOTE: Applying an external power supply to this output
will damage the instrument.
Maximum Source Current: 20 mA

One or two SPDT Electromechanical relays:
Up to four setpoints are independently set as high or low
alarm, two for each relay. Setpoint can be on Process Variable,
Deviation, PV Rate, Communication Shed or Thermocouple
Health. A single adjustable hysteresis of 0.0 to 100.0% is
provided.
