xample of Connection to SRM53D Relay Board
The SRM53D relay board allows SDV531 modules to be dual-redundant.
The SDV144 digital input modules can read back relay output statuses (up to 16 points) (*1).
The SDV144 digital input modules can also be dual-redundant.
*1:
16-point relay output statuses, including 1 to 8 points of CN1 (CN2 for dual-redundant use) and 9 to 16 points of CN5 (CN6 for
dual-redundant use), can be read over simultaneously.
