The Allen Bradley 20A-DG01 is a Safe-Off option board crafted to enhance safety in operational environments. Compatible with the PowerFlex 40P and PowerFlex 70 drive models, this unit typically utilizes an input voltage of 24 V DC for safety logic. By enabling the Safe Torque Off (STO) functionality according to the EN/IEC 61800-5-2 standard, it effectively prevents motor torque generation during critical shutdown phases.

This module meets stringent regulations, achieving SIL 2 compliance as per EN/IEC 62061 and Performance Level d under EN ISO 13849-1, ensuring robust safety measures are in place. The board incorporates a single normally closed (NC) contact that remains closed when in a safe condition. It can accommodate a maximum monitor resistive load of 250 V AC and 30 V DC, along with an identical threshold for inductive loads, providing effective performance across diverse applications.

Wire connections for terminals are supported within a range of 0.14 to 1.5 mm² (26 to 16 AWG), and terminal screw torque specifications require 0.25 N·m (2.2 lb-in). UL 508C approval further certifies its safety and reliability in industrial settings. The internal drive-mounted option board is specifically designed for environments devoid of corrosive gases, ensuring durability and longevity in various industrial applications.
