Timing Code
The first three digits are significant; the fourth is the number of zeros to follow the first
three digits. The time is expressed in milliseconds and converted to seconds. (See examples)
Examples:
M83726/28-1001P = 100 ms x 10 = 1000 ms = 1 second
M83726/28-9002S = 900 ms x 100 = 90000 ms = 90 seconds
External Resistor
Only applicable for REBM210B and REBM210L
REXT = ((T1/T0) – 1) *100k
Where:
T0 = Minimum time (nominal timing from code)
T1 = Required time
T1 < 10*T0
