Yokogawa SEC401-11 S1 ESB Bus Coupler Module I/O Signal Cable enabling communication with smart field

enabling communication with smart field devices without external multiplexing

Electrical design assumes backplane isolation but does not define field-side energization removal

Output Channels: Typically 8 channels (hardware-dependent)

and stop bits can be configured to match connected subsystem requirements

it supports up to 95% relative humidity (non-condensing)
