Omega 4002A-JC Dual Set Digital Temperature Controller
The OMEGA® 4000A Series digital controller distinguishes itself by features, construction, and operation one would expect to find only in controllers costing much, much more. Bright, easy-to-read LED digits yield an unambiguous temperature indication which is not achievable with an analog controller. The standard unit includes adjustable proportional band, manual reset, plus a metal case with full plug-in construction, allowing front removal of the entire control unit without disturbing the case and its rear wiring. Series 4000A controllers are available in single and dual setpoint models with relay outputs as a standard. Triac or 4 to 20 mA optional outputs are offered on the first point at no additional cost. Models 4001A and 4002A lend themselves to a broad spectrum of control applications: single point control, dual setpoint control, and single point control with either high or low limit alarm. Truly a quality-built controller at a remarkably low price.
Model 4002A Dual Setpoint Controller
The first setpoint of the Model 4002A incorporates the same features as the 4001A and can also be ordered with the optional Triac or 4 to 20 mA output.
The second setpoint may be set at any value within the full span of the controller. It energizes the SPDT internal relay (3 amp resistive, 120 Vac) which can be used either as an on-off control, a high limit alarm, or a low limit alarm. For an alarm with latching features an external latching relay and push button to reset are suggested.
The second setpoint is set and displayed using the same procedure as for the model 4001A, except the switch is deflected to the left and the left adjustment knob is used.
