Installed on the final expansion module, the unit closes the bus structure and maintains the defined electrical endpoint of the expansion assembly. The module is rated for a 5 V backplane supply with a 10 mA current requirement and supports Micro800 expansion configurations in both non-hazardous and Class I, Division 2 hazardous locations.\u003c\/p\u003e\n\u003cp\u003eThe Micro800 platform uses modular I\/O expansion, and the bus terminator prevents an open-ended communication path at the last connected I\/O module.
