Specifications

Controller Output
Types

Electromechanical Relays (One or Two)

SPDT contacts. Both Normally Open and Normally Closed contacts are brought out to the

rear terminals. Internally socketed.

Resistive Load:

5 amps @ 120 Vac or 240 Vac or 30 Vdc

Inductive Load (cos

= 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.

Dual Electromechanical Relays

Two SPST relays. One Normally Closed contact for each relay is brought out to the rear

terminals. This option takes the place of one of the above electromechanical relays, and is

especially useful for Time Duplex or Three Position Step Control or Position Proportional

Control applications. Instruments with this option can have a total of 4 relays plus one

current output.

Internally socketed

Resistive Load:

2 amps @ 120 Vac, 240 Vac or 30 Vdc

Inductive Load (cos

= 0.4):

1 amp @ 130 Vac or 250 Vac

Inductive Load (L/R = 7 msec):

1 amp @ 30 Vdc

Solid State Relays (One or Two)

Zero-crossing type SPST solid state contacts consisting of a triac N.O. output. Internally

socketed.

Resistive Load:

1.0 amp @ 25°C and 120 or 240 Vac, 0.5 amp @ 55°C and 120 or 240 Vac

Inductive Load:

50 VA @ 120 Vac or 240 Vac

Minimum Load:

20 milliamps

Open Collector Outputs (One or Two)

Socketed assembly replacing a relay. Opto-isolated from all other circuits except current

output and not from each other. Internally powered @ 30 Vdc.

Note: Applying an external power supply to this output will damage the instrument.

Maximum Sink Current:

20 mA

Short-circuit current limit:

100 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.
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.

Resolution:

14 bits over 0 to 21 mA

Accuracy:

0.05% of full scale

Temperature Stability:

0.01% F.S./°C

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 or when the Dual Relay Option is used.
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 120 Vac or 240 Vac or 30 Vdc

Isolation (Functional)

AC Power:

Electrically isolated from all other inputs and outputs and earth ground to

withstand a HIPOT potential of 1900 Vdc for 2 seconds per Annex K of EN61010-1.

Analog Inputs and Outputs:

Are isolated from each other and all other circuits at 850 Vdc for
