Tilt Switch Control, Model No. 21-38-4
The Control Unit is housed in a NEMA 4 enclosure with large green (“Normal”) and red (“Alarm”) indicating lights on the front cover. A 0-10 second adjustable time delay circuit in the control unit prevents momentary tilting of the switch from causing a false or premature contact transfer. Two normally-open and two normally-closed output contacts are available for connection to external alarms and/or controls. Interruption of line power causes a relay transfer. (Also referred to as model 21-38-115)
This product meets CSA approvals for use in Normal and Hazardous Areas (rating of Class I, Divisions 1 and 2, Groups A, B, C, and D T2A, Class II, Division 1, Groups E, F, and G, Class II, Division 2, Groups F, and G Class III T160°C. Ta = 85°C max).
