There are several models of the MultiFlex board that combine the functionalities of input boards, relay output boards, digital output boards, and analog output boards.

The MultiFlex combination input/output boards are designed to be replacements for the 8IO Combination Input/Output Board, but the MultiFlex board provides sev- eral new hardware options and software features.

The MultiFlex combination I/O boards consist of up to 16 combination digital/analog inputs, and a combina- tion of relay outputs, digital outputs, and analog outputs.

All boards feature both +5VDC and +12VDC output voltage points for use in powering transducers or other input devices that require power.

On the RS485 Network, the MultiFlex combination input/output boards present themselves to Einstein, E2, or REFLECS site controllers as 16AI Analog Input Boards, 8RO Relay Output Boards, 8DO Digital Output Boards, and/or 4AO Analog Output Boards, depending on what type of inputs or outputs are equipped. Dip switches are used to assign network ID numbers to each board type.

The MultiFlex combination input/output boards also support a Hand-held Terminal interface, Section 2.2.4, Hand-held Terminal (P/N 814-3110)which allows techni- cians to view input values, check relay and analog output states, and override output points with fixed digital or ana- log values. For more information on MultiFlex I/O boards, refer to the MultiFlex I/O Board Installation and Opera- tion Manual (P/N 026-1704).

Table 2-7shows the available models of MultiFlex combination input/output boards with description and part numbers.
