Timing Specifications
Timing Ranges: 0.5 to 10 / 3 to 60 sec.; 3 to 60 min.
Timing Adjustment: External resistor or potentiometer. An external
resistance of 1 megohm is required to obtain the
maximum time for all ranges. To determine the actual
resistance needed to obtain the required time delay,
use the following formula:
Treq - Tmin
x 1,000,000 ohms
max - Tmin
Accuracy: Repeat Accuracy: ± 1%
Overall Accuracy: ± 2% at R = 1 megohm.
Reset Time: 50 ms, max.
Rt =
(T
* Min. source impedance of 100 ohms.
Current Drain: Less than 5mA.

Output Switch Data
Arrangement: Solid state 1 Form A (SPST-NO).
Rating: 1A, inductive, at nominal operating voltage.
Expected Electrical Life: 10,000,000 operations at rated load.
Initial Dielectric Strength
Mechanical Data
Mounting: Panel mount with one #8 screw.
Termination: 0.250 in (6.35) quick connect terminals.
Weight: 4 oz. (112g) approximately.
