1. Momentary trigger no delay 1K ohm resistor included Note regarding DIP switch 1 Sometimes DIP switch 1 will function as an instant delay control but when it is ON its actual function depends on how DIP switch 3 is set DIP 1 setting Function OFF 1 sec momentary relay output ON DIP 3 ON Relay output latches on ON DIP 3 OFF Relay output equals 1 sec b Action If the TRG terminal is connected to momentarily the relay output immediately activates for about one second To reset the SA 025Q the TRG must be disconnected from for at least two seconds The timer has no effect c Triggering by powering unit up If DIP switch 5 is set to ON the output works the same but instead of triggering via the TRG terminal the SA 025Q is triggered by being powered up 4 Latched Output delayed Fig 5 a DIP switch settings 1 ON 2 ON 3 ON 4 Timer setting ON or OFF 5 OFF 6 OFF2. 1 The SA 025Q Programmable Timer Module is suitable for a wide range of timed security and access control operations such as door unlock timing siren or bell timer VCR timer and so on Auto sensing of input voltage and DIP switches for programming make installation easy Features Specifications Timer can be set from 1 second to 60 minutes Can be triggered via a N O positive trigger input signal or a N C negative trigger device or by powering up the unit Relay can be programmed to activate at the start or at the end of the timing cycle Relay can also be set to activate for one second at the end of the timing cycle Relay can be programmed to pulse flash or be steady on Built in reset function to manually reset timing cycle Form C relay contacts rated 8A 120VAC 24VDC LED indicates relay is energized 12VDC 24VDC operation auto sensing Current draw Less than 1mA standby or 50mA relay energized Board measures 2 7 8 x 2 1 2 73 x 63 mm Functions programmed via DIP switches no jumpers to cut Fig 1 DIP switch settings Switch 1 2 3 4 5 6 Off Fixed 1 sec Relay output time Relay energizes at start of timing cycle REPEAT timing cycle Time in MINUTES Timing controlled by TRG input Counter begin at START of TRG On Variable Relay output time Relay energizes at end of timing cycle SINGLE timing cycle
