On-Off or Time Proportional
One SPST electromechanical relay. Control action can be set for direct or reverse;
N.O. or N.C. contact selectable.
On-Off Duplex or Time Proportional Duplex
Two SPST electromechanical relays. Control action can be set for direct or reverse;
N.O. or N.C. contact selectable.
Current Proportional
21 mA dc maximum into a negative or positive grounded or non-grounded load of 0
to 1000 ohms. Output range can be set between 4 and 20 mA, and as direct or
reverse action.
Resolution: 10 bits
Accuracy: 0.5% full scale
FM Approved Output (optional)
Position Proportional
Two SPST electromechanical relays operate motor having a 100 ohm to 1000 ohm
slidewire.
Current/Time Duplex and Time/Current Duplex
Variation of time proportional duplex for Heat/Cool applications. Time proportional
output (heat or cool) is a SPST electromechanical 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.
Time Proportional Relay Resolution: 4.4 mSec
Relay Contact Ratings:
Resistive Load: 5A @ 120 Vac, 2.5A @ 240 Vac
Inductive Load: 50 VA @ 120 Vac or 240 Vac
Cycle Time: 1 to 120 seconds
Current Proportional:
Resolution: 10 bits
Accuracy: 0.5% full scale
21 mA dc maximum into a negative or positive grounded load of 0 to 1000 ohms. The
range can be set between 0 to 21 mA. It can be configured to represent any one of 10
control parameters: Input 1-2, PV1-2, Deviation 1-2, Output 1-2, Setpoint 1-2.
Auxiliary Output 2 and Auxiliary Output 3 use Control Current Output 1 and Control
Current Output 2 if Control "OUTALG" is not set to "CURRENT".
Resolution: 12 bits over 0 to 21 mA
Accuracy: 0.2% of full scale
Temperature Stability: 0.03% F.S./°C
