1. With the ON delay timer, the delay in contact operation begins before the timer coil has been energized, or turned ON. 2. The basic pneumatic timing relay is designed so that additional instantaneous contacts may be added. 3. When a timer uses the format used by the Allen-Bradley timer, the preset time can be programmed with any value from 0 to 16,000. 4. The retentive timer lets the timer START and STOP without resetting the accumulated value to 0. 5. When circuit requirements demand more time than is available from a single timer, two or more timers can be programmed together.
