Typical Applications
Figure 1 Typical Wiring Diagram.
Power requirements 20 Vdc (+1.0, -1.5), 13 mA.
Output voltage
2 to 15 Vdc direct acting; field changeable to 15 to 2 Vdc reverse acting. Calibrated at 7.5 Vdc when
dial setting matches temperature sensed by integral sensor.
Environment
Ambient temperature limits
Shipping and storage: -40 to 160°F (-40 to 71°C).
Operating: 40 to 140°F (4 to 60°C).
Humidity 5 to 95% RH, non-condensing.
Locations NEMA Type 1.
Construction
Self-contained proportional temperature controller with integral setpoint and sensing element.
Optional reset sensor available.
Setpoint dial range Refer to Model Chart.
Throttling range Pin selectable (3, 8, 12 or 20 F degrees); factory set at 8 F degrees for 3 Vdc output change.
Controlled devices Maximum of six TAC System 8000 devices.
Selectable reset ratio
All units provided with a selectable reset ratio on a prewired DIP switch for 0.7:1, 1:1, 1.5:1, or 15:1
(0.7:1 equivalent to 1:1.5).
Sensing element 1000 Ω Balco, refer to Model Chart.
Cover Beige colored plastic with brushed bronze metal insert.
Mounting
Duct Mounting plate provided; 2-1/2 in. (64 mm) standoff provides clearance if required.
Immersion (SLC-832X only) Install controller directly to an AT-226 bulb well (order separately).
Dimensions
Controller 4-3/8 H x 4-1/8 W x 4-1/2 D in. (111 x 105 x 114 mm).
Sensor insertion length SLC-832X: 6 in. (152 mm). SLC-833X: 5 ft. (1.5 m).
Connections
Refer to Typical Applications.
To optional reset ratio sensor
All units are provided with two white pigtail leads for connection to optional reset sensor (typically
TS-8501).
Terminate all pigtail leads in the 4 x 4 electrical box provided. For additional information on
TAC System 8000 wiring, refer to F-22985.
General Instructions Refer to F-22985.
