Time Delay Relays are a type of protective relays, often referred to as ‘timers’. Time Delay Relays are used to delay the start time of a device, or to delay the turn-off of a device. One example of a Time Delay Relay is the PM4HSD-S-AC24VS. The PM4HSD-S-AC24VS is a dual-voltage programmable time delay relay, with a range of features. This Time Delay Relay is suitable for a broad range of applications, including security systems, elevator control circuits, HVAC systems, industrial automation, and process control systems. The PM4HSD-S-AC24VS can be used to switch circuits on and off at predetermined intervals, and can be used to control the timing of repetitive operations.The PM4HSD-S-AC24VS features two independent time delays, with adjustable ON and OFF delay ranges of 0.1 second to 10 minutes. The time delay operating voltage is selectable for 230VAC, or 24VDC, and is protected by a built-in voltage spike protection circuit.The PM4HSD-S-AC24VS features two adjustable time delay OFF delays and an adjustable time delay ON delay. When a switch button is pressed, the OFF delay of the PM4HSD-S-AC24VS begins, and the ON delay is delayed until the OFF delay time has elapsed. The device then switches on the load, allowing it to operate for the preset ON delay time. At the end of the ON delay time, the device switches off the load.In addition to its time delay capabilities, the PM4HSD-S-AC24VS features a programmable positive-edge trigger pulse, which can switch the device’s output state when triggered. This feature makes the PM4HSD-S-AC24VS suitable for applications requiring a sequence of operations to be performed.The PM4HSD-S-AC24VS is simple to install and operate. It comes pre-installed with coordinated contacts for easy connection, and is housed in a rugged, IP67-rated enclosure for enhanced protection against dust, moisture, and other environmental factors.In summary, the PM4HSD-S-AC24VS is a versatile and robust time delay relay, suitable for a broad range of applications. Its adjustable ON and OFF delays and programmable positive-edge trigger pulse make it suitable for use in automation and process control applications. The PM4HSD-S-AC24VS can be easily installed and operated, and is housed in an IP67-rated enclosure for optimal protection against dust, moisture, and other environmental factors.
