USING PULSE INPUT DEVICES
The two pulse inputs are designed for connection to devices which have an output signal in
the form of a stream of pulses, for example:
Electricity meters with volt-free contact outputs
Fluid flow meters
Each pulse connector has two pulse signal connections, a high speed, and a low speed input.
If in doubt, use the low speed connection.
Volt-free terminals should be connected between the low speed input and pulse ground.
Devices such as optical meter readers, which require a power supply should take this supply
from the +12V DC power out pin.
Note that this power output is unregulated, and so can rise well above 12 Volts.
Up to a total of 100 milliamps may be drawn from the two pulse connector power out pins.
