Optocouplers

PSR Mini PS20 Optocoupler The 2700356 from Phoenix Contact is a mini, PSR coupling relay. It's a mini 6.8mm width and has approvals for Class I and zone 2 applications. This optocoupler will have a long-lasting life thanks to its filtering of controller test pulses and has a SIL (safety integrity level) of 3. Not to mention, the 2700356 is a DIN rail mounted module and couple's digital signals to the I.O. This coupling relay features 1 enabling current path, 1 conformation current path and 1 digital signal output. Features and benefits: DIN Rail mounted module with a 6.8mm width SIL 3 safety rating for optimum safety (according to IEC 61508) Effortless proof testing – Integrated signal contact Approved for Class I and zone 2 Great life span thanks to filtering of controller test pulses -40°C to +75°C operating temperatures Fixed screw terminal block incorporated Low inrush current QR code on housing for easy access to documentation Applications: Class I – Zone 2 High demanding Low demanding SIL 3: SIL 3, short for 'safety integrity level' is the highest, and most efficient rating. SIL aligns to the IEC 61508 standard and provides to ease of mind that the risk factor is low. Accessories: Flat marker strip – 627-2037 Standards IEC 61508, EN 61511
