Signal Connections and Configuration
The SED2D-11 provides four groups of four channel connections for digital field signals. It connects to the Yokogawa SDV521 digital I/O module through an AKB651 connection cable.
In addition, the terminal board supports both single and dual-redundant configurations. For dual-redundant operation, users must connect the corresponding connector pairs according to the system configuration. Therefore, check the required wiring arrangement before installation.
Electrical Characteristics
The SED2D-11 has a dielectric withstand rating of 2000 V AC for 1 minute. It also provides a minimum insulation resistance of 100 MOhm at 500 V DC. These values define its electrical insulation performance under the specified test conditions.
Furthermore, the M4 screw terminals provide connection points for field wiring. Users should check the terminal arrangement and cable requirements against the applicable system documentation before connecting field devices.
