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 that support 0 to 20mA, 4 to 20mA and 0 to 30V. Plus 2 analog outputs to interface with BMS and other systems. The analog outputs support 0 to 20mA, 4 to 20mA and 0 to 10V. Analog inputs and outputs are sampled by the host meter at a 1/2 cycle (8-10ms) rate. The option modules are attached to the side of the meter providing connection for control power and interfacing bus. The PowerLogic PM8000, ION7400 and ION9000 devices allow up to 4 input/output option modules per meter.
