Multi-Range Delay On Make
A1M Series

The A1M Series is a Delay On Make time delay relay featuring easy to program multiple time ranges and digital time selection with extremely high accuracy and repeatability. Programming is accomplished using a 5 position rotary switch to select one of five time ranges. A 3-digit pushbutton switch selects the amount of time delay required.

File #E59090 Microprocessor Controlled Timing Circuit Easy 3-Digit Time Cycle Setting Time Cycles From 50 mS To Over 16 Hours Superior Transient Protection Flame-Retardant Polycarbonate Housing	100% Life Tested Five Time Ranges, User Selectable ± 0.1% Repeatability Timing Light Reinforced Base Locator Pin Made in U.S.A.

Time Delay Adjustment: 3-digit pushbutton switch Range: 50 mS to 999 minutes in 5 ranges Repeatability: ± 0.1%, ± 20 mS over specified timing range Accuracy: ± 1% of set time, plus fixed error of 80 mS max. (40 mS typical including power on response time) Input Operating Voltage: 24, 120, 240 VAC, 12, 24 VDC ± 10% (D.C. models have reverse polarity protection. Unfiltered input voltage to them must be full-wave rectified) Power On Response: 50 mS max. Power Off Reset Time: 150 mS min. Start Switch Closure Time: 200 mS to initiate timing cycle; 50 mS to reset delay during cycle Power Consumption: 2 VA maximum Frequency: 50/60 Hz Output Type: Relay Contacts, D.P.D.T. (2 form C)            Silver Cad. Oxide material Rating: 10 amp. max. resistive at 240 volts A.C. 100 mA at 5 VDC min. load current Life: Mechanical - 10,000,000 operations           Full Load - 500,000 operations Timing Light Logic: Flashing during timing; continuously on after time out

Protection Transient Voltage: 12, 24 volt timers are protected by an 8.8 joule metal oxide varistor; 120, 240 volt timers are protected by a 30 joule metal oxide varistor. Dielectric Breakdown: 1500 VAC RMS minimum at 60 Hz between input and outputs and between outputs. Mechanical Termination: 8 - pin plug Mounting: Socket Mount - Part No. MSO-0008P-012 Environmental Storage Temperature: -23°C to 70°C Operating Temperature: -23°C to 55°C Humidity: 95% relative Timing Selectable Time Ranges:     .05 to 9.99 seconds     .1 to 99.9 seconds      1 to 999 seconds     .1 to 99.9 minutes      1 to 999 minutes (Times less than 50 mS are not recommended due to the response time of the mechanical relay) Programming: To program the timer, remove power from the unit and select the time range, use the digital switches to select the required time (0-999)
