Output Pulse Specifications
1. All outputs are isolated from ground and each other.
2. Outputs are rated for DC only, from 3.0 volts to 30.0 volts.
Observe polarity.
3. The corrected volume pulser circuits will sink up to
15 milliamperes (DC) for Form-C outputs and up to 5
milliamperes (DC) for Form-A outputs.
4. The electronic Form-C volume output counts consist of contact
closures between both the K- Y and the K-Z terminals. For
proper counting, the receiving device must count both.
The pulse-off time for Form-A pulses can be varied by the selection of item 115. If the board jumpers are
configured for Form-C, then Item Code 115 controls the pulse width of the Form-C pulses.
