The 349PDM is a digital I/O module. It has 12 solid-state output channels, each capable of 15A, 4 5A capable relays, and 4 digital inputs that can be configured as active high or active low. The 349PDM features a manual mode to allow the operation of outputs and relays without a functioning E-Plex connection. The total current handling capability is 75A and we recommend that a supply breaker or fuse of 80A maximum is used. The module is split into two sides, and channels 2 and 3 on each side are diode-protected against backfeeding.

On some Cruiser Yacht vessels, an additional remote session may be required in order to program the second side of the new module.
