Siemens 6ES5 470-7LB13 Analog Output Module

Siemens 6ES5 470-7LB13 is an eight-channel analog output module for the SIMATIC S5-115U/H/F PLC family. The LB13 variant provides eight isolated voltage outputs in the bipolar ±10 V range, with floating outputs. This module is part of Siemens’ 6ES5 470-series analog I/O and is designed for legacy S5-115U/H/F installations that require voltage control signals within a ±10 V range. Because the LB13 outputs are voltage-type (not current-loop), it suits applications where control signals are referenced to a bipolar voltage range rather than a current loop. The LB13 designation distinguishes it from the LA13 variant, which in the same family offers additional current-capable outputs (e.g., ±10 V with 0-20 mA). As with other S5 I/O modules, proper integration involves matching signal ranges and ensuring compatibility with devices that accept ±10 V analog inputs. The 6ES5 470-7LB13 is documented in Siemens migration and peripheral adapter literature as the eight-channel, bipolar voltage-output analog module for S5-115U/H/F systems.
