One or two externally mounted triac N.O. outputs for use with open collector
outputs.

10 amps @ 55 ˚C and 120 or 240 Vac
Inductive Load:
50 VA @ 120 Vac or 240 Vac
Motor Rating:
1 HP @ 25 ˚C
0.75 HP @ 55 ˚C
Controller Output Algorithms On-Off or Time Proportional
One relay or open collector output. Control action can be set for direct or reverse.
Time Proportional Relay Resolution:
3.3 msec
On-Off Duplex, Three Position Step Control, or Time Proportional Duplex
Two relays or open collector outputs. Control action can be set for direct or
reverse.
Time Proportional Relay Resolution:
3.3 msec
Current Proportional
A single 4-20 mA current output signal which can be configured for direct or
reverse action.
Current Proportional Duplex
A single split current output for both heat and cool (4-12 cool, 12-20 heat) or a
combination of current proportional output (Heat = 50 to 100% of range) and
auxiliary current output (Cool = 0 to 50% of range). Both are 4-20 mA signals
which can be set for direct or reverse action.
Position Proportional
Two SPDT electromechanical or solid state relays operate motor having a 100
ohm to 1000 ohm feedback slidewire.
Current/Time Duplex
Variation of time proportional duplex for Heat/Cool applications. Time proportional
output (heat or cool) is a relay. Current proportional output (Heat or Cool) is a 4-20
mA signal that can be fed into a negative or positive grounded load of 0 to 1000
ohms and is operational over 50% of range or the entire range.
