Five digital inputs and two relay outputs give you monitoring and switching capability for a single safety zone. Start input and feedback input allow reset monitoring and device status reporting back to the PLC. ## Ratings that matter for the panel The 80 ms maximum fault-reaction time sets the worst-case stop delay you need to factor into your risk assessment and stopping-distance calculation. Typical response runs 40 ms under normal conditions. Mounts on DIN rail via screw and snap-on; any orientation. Ambient during operation -25 to +60 °C; at 3 000 m max +50 °C, at 4 000 m max +40 °C (no protective separation). Terminal block accepts 1x 0.5–4.0 mm² or 2x 0.5–2.5 mm² solid/stranded — standard for the control cabinet. Depth is 124 mm; plan for cable bending radius inside the enclosure. ## Sourcing posture Active current lifecycle. No announced discontinuation or phase-out. Procurement can commit the line with confidence. RFQ required for firm pricing and lead time.","metaTitle":"Siemens 3UF7320-1AB00-0 Safety Relay, 24V, 80ms","metaDescription":"Active production safety relay from Siemens. 24V rated, 2-channel safety outputs, max 80ms response time.
