Application
The analog input module (MPC-8AI) is an expansion
module that plugs directly into any of the four option
slots available on the TAC MicroSmart Multi-purpose
Controller (MSC-MPC), providing additional analog
inputs to the MSC-MPC.
The MPC-8AI provides eight universal analog inputs
that can be configured as 1000 ohms Balco, 1000 ohm
platinum, 4-20 mA, 0-11 Vdc sensors, or status contact
inputs.

Installation Guidelines
FCC Guidelines
This equipment has been tested and found to comply with the
limits for a Class "A" digital device, pursuant to Part 15 of the
FCC rules.
These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated
in a commercial environment. This equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual
may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Pre-Installation
Warning: To reduce risk of fire or electrical shock, install in
a controlled environment relatively free of contaminants.
Before beginning the installation process for the MPC-8AI,
visually inspect the unit for any obvious defects and to make
sure all parts are included. If any flaws are detected, contact
your local TAC office or authorized representative
immediately.
