Woodward 5466-258 Simplex 48/24 Discrete Input/Output Module
Description:
5466-258 is Woodward Simplex 48/24 Discrete Input/Output Module. 5466-258 contains circuitry for forty-eight discrete inputs and twenty-four discrete outputs. These modules have no potentiometers and require no calibration. A module may be replaced with another module of the same part number without any adjustment. There are two different FTM I/Oconfigurations for the 48/24 Discrete Combo Module.
Configuration 1 consists of one 48/24 Discrete FTM connected to the 48/24 Discrete Combo module via two Hiah Density Analog/Discrete cables. The 48/24 Discrete FTM is then connected to either two 16Ch Relay Modules or one 32Ch Relay Module via a Low Density Discrete Cable(s).
The discrete inputs are optically isolated and accessible through either the 48/12Discrete FTM or the 24/12 Discrete FTM depending on the configuration. Thediscrete outputs are accessible through either the 24/12 Discrete FTM or the two16Ch Relay Modules or the one 32Ch Relay Module when so configured. SeeFigures 8-2 and 8-7 for examples of configurations.

FAQ:
How to install 5466-258?
The modules slide into card guides in the control's chassis and plug into themotherboard. The modules are held in place by two screws, one at the top andone at the bottom of the front panel. Also at the top and bottom of the module aretwo handles which, when toggled (pushed outward), move the modules out justfar enough for the boards to disengage the motherboard connectors.

What's the meaning of 48 and 24?
48 is the discrete inputs number of channels, 24 means the descrete output number of channels.
