Board Assembly

There are three different fixed boards, two optional relay boards and an optional Modbus board which make up the PCB Assembly. Depending upon requirements, either a Electromechanical or Solid State Relay Board module can be used. Boards are field replaceable. Simply loosen the three locking standoffs, remove one board, insert the other board and tighten screws.

Note: Boards are susceptible to ESD. Refer to Appendix A, "Electrostatic Sensitive Device (ESD)", on page 20.
