ABB 2TLA010070R0000 Safety Relay Module Industrial Grade

ABB USR10 2TLA010070R0000 is an industrial‑grade DIN‑rail mounted safety relay module that acts as a universal safety relay/timer with delayable relay outputs. It provides 3 normally open (NO) and 1 normally closed (NC) contacts, all powered from a +24 V DC input and wired through screw terminals for robust field connections. The device is part of ABB’s safety relay family and is designed to supervise safety circuits in automation setups, enabling safe sequencing and control of machinery through its delayable outputs. The compact 24 V DC module is intended for DIN rail installation and supports straightforward integration with safety switches and protective interlocks to form compliant safety circuits; typical operating conditions include an IP20 enclosure and an operating temperature range from -10 to +55 °C.
