REDUNDANCY MODULE Cost Effective Solution to Build Redundant Systems Dual Input with Single Output Two Diodes (Common Cathode) DC12-48V (120V) ±25% Wide-range Input Full Power Between -40°C and +60°C Width only 32mm Rugged Metal Housing Quick-connect Spring-clamp Terminals Easy Wiring: Distribution Terminal for Negative Pole Included 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA The YR2.DIODE is a redundancy module, which can be used to build 1+1 and N+1 redundant systems. It is equipped with two input channels, which can be connected to power supplies with up to 10A output current and one output, which can carry nominal currents up to 20A. The module is suitable for power supplies with constant current overload behavior as well as any kind of “Hiccup” overload behavior. Input voltage The YR2.DIODE is the perfect solution to use in a redundant system, if the power supply itself is equipped with a DC-OK signal (e.g.: DIMENSION Q-Series). In addition to the YR2.DIODE is the YRM2.DIODE which has a monitoring circuitry included. LEDs and relay contacts signal when one of the two DC-input voltages is not in range due to a non-functioning power supply. Another interesting application for this diode module is to separate sensitive loads from non-sensitive loads. This avoids the distortion of the power quality for the sensitive loads which can cause controller failures. Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.

□innefUSIOfU Y-Series DC12-48V (120V), 20A, DUAL REDUNDANCY MODULE I 5. LIFETIME EXPECTANCY AND MTBF_ The redundancy module has two input channels which are completely independent from each other. Each control circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input redundancy module can be considered as two single redundancy modules combined together in one housing. The only common point is the circuit trace that ties the two separate circuits together at the output. The MTBF figures below are for the entire dual input...
