h1. Relays
The FAC-2100 can be ordered with a Standard or Enhanced Relay Board.  


h1. Standard Relay Board
The Standard Relay Board contains four Form-C mechanical relays.  This is the default ordering option and does not require any additional order codes post-pended to the model number. 


h1. Enhanced Relay Board
The Enhanced Relay Board contains three Form-A solid state relays and two Form-C mechanical relays.  To order a FAC-2100 with the Enhanced Relay Board, post-pend the model number with '-RX{~}2{~}X{~}3{~}X{~}5{~}', where:
* X{~}n{~} is either an 'A' or 'D' and specifies if the output is {*}A{*}C or {*}D{*}C, and 
* n in X{~}n{~} is the solid state relay number.  

The most common option is '-RAAA' for an Enhanced Relay Board with three AC solid state relays.

Solid state relays offer near zero volt turn-on and near zero current turn-off.  This feature makes them ideal options for applications that need to switch inductive loads such as a solenoid or motor.
