AM-MIO: Input-Output Expansion Interface (Discontinued)

The Model AM-MIO Input-Output Expansion Interface is an expandable input/output interface designed for use with Linear’s AM3Plus, AE1000Plus, & AE2000Plus access control systems.

Housed in a lockable cabinet, the basic AM-MIO consists of two modules: a power supply module (PSM) and a relay/loop module (RLM). Up to three additional RLM modules can be added to fill the five-position module “rack”. Each RLM module provides six Form “C” (normally open & normally closed) 5-amp relays for outputs and eight supervised loop terminals for inputs. With four RLM modules, the AM-MIO is capable of controlling 24 relay outputs and 32 loop inputs. Each module has a rotary switch to select its unique remote device address. The device address identifies each module to the system. Each module is interconnected to the controller by daisy-chained cables.
