DISCRETE OUTPUTS
Available as (3) Solid State NFET, or (3) Form A relay.
Solid State Output:
Type: Switched DC, N Channel open drain MOSFET
Current Rating: 1 A max
VDS ON: 0.3 V @ 1 A
VDS MAX: 30 VDC
Offstate Leakage Current: 0.5 mA max
Form A Relay Output:
Type: N.O.
Current Rating: 3 Amps @ 125 VAC

Life Expectancy: 200,000 cycles at maximum load rating. (Decreasing
load, increasing cycle time, and use of surge suppression such as RC
snubbers increases life expectancy.)

Cycle Time: Programmable from 0.0 to 60.0 sec
Auto-Tune: When selected, sets proportional band, integral time,
derivative time values, and output dampening time
Input Fault Response: Upscale
ALARMS
Modes: Manual
Absolute High Acting Absolute Low Acting
Deviation High Acting Deviation Low Acting
Inside Band Acting Outside Band Acting

ANALOG DC OUTPUT
Software programmable for 0-10 VDC, 0-20 mA, or 4-20 mA
Resolution:
Voltage: 500 μV
Current: 1 μA
Accuracy:
0.1% of full scale (18° to 28°C)
0.2% of full scale (-40° to 70°C)
