Specifications
• Carlin’s Model 90200H microprocessor operated temperature control
is designed to operate 135-ohm modulated devices, replicating older
slidewire devices, and is available in configurations described below.
Note that 90200H/HT controls require a 120-volt power input. The 135-
ohm circuit is isolated.
• For electronic mod motor control systems, such as Siemens SQ5, consult
manufacturer.
• Refer to separate product listing sheets for pre-defined models, or re-
quest a control to meet your specifications (within the available ranges
listed below).
