Delay timer relay 10-function 0.1S~100HRS 24~230V mains
Crouzet MUR1 Electronic Multifunction Multirange Timer
For full specification, functions and electrical ratings please consult the following crouzet pdf. doc:

Full Timing Range [all possible values]: 0.1sec to 100hours
Seven Ranges [selected using screwdriver operated dial switch]: 0.1~1sec, 1~10sec, 6~60sec, 1~10min, 6~60min, 1~10hour, 10~100hours. Analogue dial adjusts the preset delay from between the lower and upper value of the selected range [e.g from 0.1 to 1second and all values between].
Ten Selectable Timing Functions: see below
Power Requirements 24..240v ac OR 24Vdc . Unit automatically detects input voltage and powers up from any voltage in this range. No voltage selector switches or links.
Output : SPDT [same as SPCO i.e. single pole change-over relay] rated 5A 250vac max. Output contacts are volt-free. i.e. output switching contacts are totally independent of voltage used to power unit. Hence the relay can be used to switch any supply or signal within maximum rating.
Indicators: State displayed by single led indicator. Coded flashing indicates power, timing and operation.
Functions: Standard On-delay and On-Pulse functions PLUS Symmetrical Repeat Timer Functions x2 PLUS unit can be continually powered and an off-delay [release delay] or on-pulse initiated via a "control switch" linking to connections A1 and Y1. The "control switch" could be a remote switch, relay, triac [for ac power], transistor [for dc power] or switching sensor output.
80-Series On Delay Diagram "A" ON-Delay. Timing commences as power is applied. The output contacts transfer after preset time has elapsed. Reset occurs when power is removed and timing will begin again from zero if power is re-applied.
80-Series On Pulse Diagram "H" On pulse without control switch. Bog-standard ON-pulse function. i.e when power is applied the relay switches and timing commences. The relay de-energizes when the time has elapsed.
80-Series Signal ON Pulse Diagram "B" On-pulse with control switch Power is permanently applied to the timer. On momentary or maintained closure of an external Control Switch the output contacts transfer, and remain so for the duration of the preset delay, after which they reset.
80-Series Signam OFF Delay Diagram "C" Release Delay . Also known as off-delay. Power is permanently applied to the timer. The output contacts transfer immediately on closure of the Control Switch. Opening the Control Switch initiates the preset delay, after which time the output contacts reset.
"D": Symmetrical recycler [with pause start]: Also known as repeat cycle. Apply power to timer. Timing commences. Relay is energized after preset delay, T. Timing repeats for T and relay de-energizes. Repeats Indefintiely. i.e Relay is OFF [for T] then ON [for T] then OFF [for T] etc for as long as power is applied. The ratio is 1:1 (time on = time off).
"Di": Symmetrical recycler [with pulse start]: Same as above but relay energizes immediately as power is applied and then de-energizes after the first timing period. Repeats Indefinitiely. i.e Relay is ON [for T] then OFF [for T] then ON [for T] etc for as long as power is applied. The ratio is 1:1 (time on = time off).
Timer also features four more timing functions. These are slightly more difficult to describe. "At", "Ht", "Ac" and "Bw" [see pdf for diagrams]
Timing adjustment is approximate but the timer is oscillator/microprocessor controlled with accurate repeatability. Do not expect to be able to set times with stop-watch precision. This is not a programmable clock or a programmable digital timer.
Mounting: See Picture. Din-Mounting clip on rear of module. Clips to standard 35mm [consumer unit style] din rail. Standard single module 17.5mm width [i.e. it takes up one MCB worth of rail space]. Low profile miniature case design: The timer can be mounted alongside standard MCB's saving on installation time.
CONDITION: New timers. Perfect condition.
