Pulse Inputs - Obvius AcquiSuite Ally 12 User Manual

AcquiSuite Ally 12 & 48 User Guide (Rev D)

Pulse Inputs

Ally ACM12 meters are equipped with 4 pulse inputs and Ally
ACM48 meters (hardware version I) are equipped with 2 pulse
inputs. Pulse counting supports accumulation of consumption
data from any external meter using a dry contact (Form A Relay)
or open collector outputs. The AcquiSuite Ally pulse inputs are
compatible with "low speed" meters. The pulse duration must
exceed 50mS in both the logic low and high state allowing for a
maximum input frequency of 10 Hz.
Pulse scaling, resetting and accumulated values are accessed through registers and are "system" in scope.
Refer to the register list, Obvius Ally Configuration Console, or videos for more information.
