Podwójny wyłącznik krańcowy Honeywell SW2

Honeywell SW2 double limit switch (2xSPDT) is an auxiliary switching device designed for use with Honeywell actuators of series N20, N34, S10, S20, CN20, CN34, MVN20, MVN34 and others. It allows organizing additional signaling circuits, limit position control or control of external devices (e.g., pumps, lamps or other automation components) depending on the position of the regulating element (damper or valve). If in your automation system auxiliary functions stop working when the damper reaches the end position, or if the actuator does not stop at the required point, the cause may be a malfunction of this switch. Technical specifications: Parameter Value Part numbers SW2, 534.172.002 Manufacturer Honeywell Device type Double limit / auxiliary switch Number and type of contacts 2x SPDT (two separate single-pole switches with normally open (NO) and normally closed (NC) contacts) Electrical ratings 5A (resistive) / 3A (inductive) at 110/230 V AC Application Honeywell actuators of series N20, N34, S10, S20, CN20/CN34, MVN20/MVN34 and others Adjustment Switching points adjustable (user-set) Mounting External (attached to actuator, connected to its terminal block) Key advantages: Expanding actuator functionality: SW2 provides up to two additional independent position signals, necessary for complex building management systems (BMS) and industrial boiler plants. Adjustment flexibility: Unlike built-in limit switches which are fixed at 0% and 100%, SW2 switching points can be freely adjusted manually.
