The SD2 is an ETA module that is used to indicate a program error code which requires a manual reset. The module includes a manual reset switch that can be pressed to route a reset signal to a controller. The polarity of the reset switch can be set to Normally Open (NO) or Normally Closed (NC) operation via the jumper on J2. When the reset switch is pressed, Terminals #3 and #4 of J1 are either connected or disconnected. Two 7-segment displays are available at the edge of the module, denoting where the input signal is within the range.

The SD module receives an input signal from a controller, and then displays a number from 0 to 10 up to 0 to 50, depending on the jumper position of J3. It can accept a current input of either 0 to 20mA or 4 to 20mA or a voltage input of 0 to 10V or 2 to 10V. The unit is typically mounted in a BP2, BP4, BP8 or BP4V Backplane with power provided by the Backplane; however, the unit can be powered directly with an alternate DC supply. The green LED indicates that power is available to the module.
