Mode of
Two relays or open collector outputs. Control action can be set for
direct or reverse.
Time Proportional Relay Resolution: 3 msec
: A single 4-20 mA current output signal that
Current Proportional
can be configured for direct or reverse action.
Current Proportional Duplex
can provide both heat and cool signals (4-12 mA cool, 12-20 mA
heat) or a combination of both current outputs with the First
Current Output providing the Heat output (Heat = 50 to 100% of
range) and Second Current Output providing the Cool output
(Cool = 0 to 50% of range). Both are 4-20 mA signals that can be
set for direct or reverse action.
Position Proportional
motor having a 100-ohm to 1000-ohm feedback slidewire.
Current/Time Duplex
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.
