Model 7SD - Deviation Display
The 7SD is a 1/16 DIN heat (OP1) plus optional alarm (OP2) controller
with a single 3 digit, 7 segment display, bargraph deviation display
and front panel LED's to indicate heat ON, alarm ON and Autotune
ENABLED. Configuration and calibration protection is afforded by
both a configuration password and an internal jumper. When loss
of sensor input occurs, the Auto Comp sensor break feature maintains
control at the present percent output.

Model 7SM - Dual Display
The 7SM has all the features of the 7SD (except
the bargraph display) but with a dual 3 digit, 7 segment display
to show both process value and setpoint.
Model 7SH - Heat/Cool
The 7SH controller is a 7SM with heat/cool capability
(OP2 relay=Cool). The relative cooling gain can be set from 1.0
to 0.2 (1x to 5x the heating proportional band). Configurable overlap
and deadband allows customization of the 7SH for unique process
heat/cool requirements.
