PRO RM 20, Redundancy Module 24VDC

The Weidmüller PRO RM 20 is a DIN rail redundancy module that decouples two 24 V DC power supplies onto a common load so the surviving unit carries the panel if one fails. It decouples with MOSFETs rather than diodes, so the drop across the module is around 0.2 V and self-heating stays low, which is why it is used ahead of diode blocks on high-current 24 V distribution.

• Function: MOSFET decoupling of two 24 V DC supplies for redundant operation
• Input: 24 V DC rated, 10-32 V DC; 2 x 20 A (45-60 °C), 2 x 24 A to 45 °C
• Output: Input voltage less 0.2 V; 40 A (45-60 °C), 48 A to 45 °C, 30 A at 70 °C
• Voltage drop: 0.2 V typical
• Connection: PUSH IN, 4 input and 2 output terminals
• Mounting: Horizontal on TS 35 DIN rail
• Temperature: -40 °C to +70 °C
• Dimensions: 38 x 130 x 125 mm (W x H x D)
