Each step provides both an open-collector output and an SPST dry contact relay, so it can drive relays, power controllers or equipment remote inputs. A single front-panel control sets the interval between steps from 1 to 10 seconds.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ru-sq6a.jpg\" alt=\"RDL RU-SQ6A 6-Channel Power Sequencing Controller\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eControl and output connections are made on clearly labeled rear-panel detachable terminal blocks. Each of the six steps has an open-collector output rated 50 mA continuous and an SPST relay contact rated up to 2 A switching current. A single-turn TIMING INTERVAL control sets the delay between channels, and an internal microcontroller keeps timing accurate. The sequence is started by a front-panel SEQUENCE CONTROL pushbutton or, when set for remote operation, by grounding the rear-panel ACTIVATE terminals. Releasing the request turns outputs off in reverse sequence. If ACTIVATE is permanently grounded in remote mode, outputs sequence on when power is applied and all turn off together when power is removed. Front-panel LEDs show each channel's state, the UP REQUEST, sequence COMPLETE and whether front-panel or remote activation is selected. When the sequence completes, the Sure-Lok supervisory circuit latches the outputs on until the user deactivates the sequence. The module draws 24 Vdc at 100 mA plus any load on its 24 Vdc output; RDL recommends the PS-24AS (USA) or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX\u003c\/a\u003e (international) power supply, not included.
