The device features:
 A relay (terminals 37 and 38 of
temperature is exceeded, which can be programmed in
LED.
 A fully programmable alarm relay (terminals 39, 40 and 41 of
ALARMS"
 Two digital outputs, optoisolated NPN transistors (terminals 34, 35 and 36 of
programmable; see
Computer SMART III 6 model:
 Six output relays (terminals 15 to 21 of
itors.
