KCD2-SOT-Ex2, Switch Amplifier

Switch Amplifier, KCD2-SOT-Ex2 2-channel isolated barrier 24 V DC supply (Power Rail) Dry contact or NAMUR inputs 2 passive transistor outputs Reversible mode of operation Line fault detection (LFD) Housing width 12.5 mm SIL 2 (SC 3) acc. to IEC/EN 61508 This isolated barrier is used for intrinsic safety applications. The device transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area. Each input controls a passive transistor output. Via switches the mode of operation can be reversed and the line fault detection can be switched off. A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
