    Application Information CM-2201/CM-2202 2.0 General Application Information The CM-2201/CM-2202 are designed to operate on input voltages between 100 and 277 Vac and 50/60Hz. Load switching is handled by a 2-Pole solid-state relay and can control resistive loads of 30A continuous @ 40°C ambient. The CM-2201/CM-2202 are designed to control heating circuits by monitoring one or two temperature inputs for each circuit via industry standard 3-wire, 100Ω, Platinum...

  • Page 10 CM-2201/CM-2202 General Operation 5.9 Soft-Start Feature The Soft-Start feature enables self-regulating cables to be energized at low temperatures without causing excessive load on the electrical system and extending cable life by reducing cable internal heating due to inrush currents. The resistance of self-regulating cables decreases as the cables get colder, which results in higher current and can result in breaker trips if temperatures are very cold and the...
