Optional input output module compatible with PowerLogic PM8000, ION7400 and ION9000 devices that provides additional analog inputs and analog outputs. This analog module provides 4 analog inputs supporting 0 to 20 mA, 4 to 20 mA and 0 to 30 V. Plus 2 analog outputs for connection to BMS and other systems. The analog outputs support 0 to 20 mA, 4 to 20 mA and 0 to 10 V. Analog inputs and outputs are sampled by the main meter at a rate of 1/2 cycle (8-10 ms). The option modules mount on the side of the meter and provide the connection for the control voltage and interface bus. The PowerLogic PM8000, ION7400 and ION9000 devices allow up to 4 input/output option modules per meter.
