产品详情

  control
action: reverse (heat) or direct (cool)
modes: time and amplitude proportional control modes; selectable manual or auto pid, proportional, proportional with integral, proportional with derivative with anti-reset windup and on/off
rate: 0 to 399.9 seconds
reset: 0 to 3999 seconds
cycle time: 1 to 199 seconds; set to 0 for on/off operation
gain: 0.5 to 100% of span; setpoints 1 or 2
damping: 0000 to 0008
soak: 00.00 to 99.59 (hh:mm), or off
ramp to setpoint: 00.00 to 99.59 (hh:mm), or off
autotune: operator initiated from front panel for 1 input at a time only 

outputs 
there are two physical outputs: output 1 = rh, output 2 = temp 
functions are set up as outputs (pid or on/off), or alarms
ordering output choices:
    relay: 250 vac @ 3a or 30 vdc @ 3a (resistive load); form c spdt
    ssr: 20 to 265 vac @ 0.05 - 0.5a (resistive load); continuous
    dc pulse: non-isolated; 10 vdc @ 20 ma (used with external ssr) 
    analog output (output 1 only): non-isolated, control or retransmission 0 to 10 vdc or 0 to 20 ma; 
     500 ohm max, accuracy is ±1% of fs 

control output 1 and 2
operation:
    action: reverse (heat) or direct (cool)
    modes: time and amplitude proportional control modes; selectable manual or auto pid, proportional, proportional with integral, proportional with derivative with anti-reset windup and on/off 

alarm 1 and 2 (programmable)
1) alarms are used for color changing sequence of alarm status (visual alarm). 
2) alarm functions are active, in addition to the color changing functions, if output 1 & 2 are (menu) disabled.
3) if alarms are disabled, output menus (pid or on/off) are active. color change is still active.
operation: high/low, above/below, band, latch/unlatch, normally open/normally closed and process/deviation; front panel configurations
-al limit alarm version: output 1 & 2 submenus used for pid are eliminated from menu. color sequence based on alarm setpoints is still available.
