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.
