YRM2.DIODE DC24-48V, 20A, DUAL REDUNDANCY MODULE REDUNDANCY MODULE Cost Effective Solution to Build Redundant Systems Dual Input with Single Output Alarm Relay-contacts for Each Input Path Two Diodes (Common Cathode) DC 24-48V ±25% (18-60Vdc) Wide-range Input Full Power Between -40°C and +60°C Width only 32mm Rugged Metal Housing Large Screw Terminals Easy Wiring: Distribution Terminal for Negative Pole Included 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA The YRM2.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 Input voltage range Input current The YRM2.DIODE has a monitoring circuit included and is the perfect solution when the power supply has no DC-OK function. Two LEDs and two relay contacts signal when one of the two DC-input voltages is not in range due to a non-functioning or disconnected power supply. In addition to the YRM2.DIODE is the YR2.DIODE which has no monitoring circuitry included. This is the perfect fit when the power supply itself is already equipped with a DC-OK signal (e.g.: DIMENSION Q-Series). Large screw terminals allow an easy installation and a huge international approval package for a variety of applications makes this unit suitable for nearly every situation.

If one input voltage is too low or completely lost, it will be indicated by an alarm relay contact. Each input has its own monitoring circuitry and relay contact. Alarm threshold nom. 21.5V (±0.5V) Relay contact opens immediately after the input voltage falls below this value. Isolation voltage see dielectric strength table in section 14.

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 module. If the...
