Digital Outputs
Standard Digital Outputs
System Digital Outputs
Number 34 continuous 10 mA sink referenced to +5 Vdc of MLS
for SSR operation; 20 mA momentary peak sink.
User selectable outputs 34 PID control, Alarm/control, or Events. Two outputs are
not PID programmable.
Number of PID loops 16 or 32 programmable loops. 16-loop systems have dual
outputs. 32-loop systems have 32 single outputs, and you
can individually configure outputs 17-32 as a second out-
puts for loops 1-16.
PID control outputs Time Proportioning, Distributed Zero Crossing, or On/
Off--all independently selectable for each loop.
Cycle Time 1-255 seconds.
Control Action Reverse (heat) or Direct (cool), independently selectable
for each loop.
Off State Leakage Current <.01 mA to DC common.
