Model 4201A Single Setpoint Proportional Controller This versatile digital controller can be operated as a proportional controller with the adjustable bandwidth up to 3% of full span. The setpoint temperature is always available. Simply push the spring-loaded setpoint switch to the right, and the setpoint is digitally displayed. To change the setpoint, with the switch deflected to the right, adjust the knob to the right of the switch until you get the desired reading. The standard Model 4201 has an internal SPDT relay (7 amp resistive at 120 Vac). This model is also available with optional Triac or 4 to 20 mA output in place of the relay. See Options and Specifications for more information.
Model 4202A Dual Setpoint Controller The first setpoint of the Model 4202A incorporates the same features as the Model 4201A and also can 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 an SPDT internal relay (3 amp resistive 120 Vac) which can be used as either 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 4201A except the switch is deflected to the left and the left adjustment knob is used.
