Product details

This GS describes the hardware specifications of thesafety node unit (SNB10D). The safety node unit isconnected to the safety control unit. The safety nodeunit has an interface function to transmit analog inputsignals and contact signals from the field to the safetycontrol unit via an ESB bus. It also has a function tosupply power to I/O modules.

The safety node unit is mounted with power supplymodules, ESB bus interface modules, optical ESB busrepeater modules, and I/O modules.

For details on the I/O modules, refer to the generalspecifications (GS 32Q06K30-31E and GS 32Q06K40-31E).
