Frequently Asked Questions (FAQ)

• Q: Is the 1756-RM2 a genuine Allen-Bradley product?
  A: Yes, this module is a brand new, original Allen-Bradley 1756-RM2. We do not sell used or counterfeit items.
• Q: What synchronization speed can I achieve with the 1756-RM2?
  A: When pairing two 1756-RM2 modules, the speed reaches up to 1000 Mbps. Using series A or B modules limits speed to 100 Mbps.
• Q: How fast is the controller switchover time?
  A: The 1756-RM2 achieves a controller switchover time of up to 20 ms. This ensures minimal disruption during failover events.
• Q: Which controllers work with the 1756-RM2?
  A: The module supports ControlLogix 5560 and 5570 series controllers. For best scan performance, pair it with 1756-L7x controllers in both chassis.
• Q: What fiber cable do I need for the 1756-RM2?
  A: Use 8.5/125 micron single-mode fiber-optic cable with LC-type connectors. Recommended cables: 1756-RMC1 (1m), 1756-RMC3 (3m), or 1756-RMC10 (10m).
• Q: What is the maximum distance between two 1756-RM2 modules?
  A: The module supports a maximum fiber distance of 10 kilometers. However, placing the redundant chassis close together provides better performance.
• Q: Can I install I/O modules in the redundant chassis pair?
  A: No. I/O modules, intelligent modules, and encompass partner modules cannot reside in either redundant chassis. Install them on a third or higher-order chassis.
• Q: What are the power requirements for the 1756-RM2?
  A: The module draws 1.16 A at 5.1V DC and 3.4 mA at 24V DC from the backplane. Maximum power dissipation is 6 Watts.
• Q: What is the operating temperature range?
  A: The 1756-RM2 operates reliably from 0°C to 60°C (32°F to 140°F).
• Q: What is your return policy for the 1756-RM2?
  A: We accept returns within 30 days of delivery. Contact our support team for RMA authorization.
• Q: Do you have the 1756-RM2 in stock?
  A: Yes, we keep the 1756-RM2 in stock with ready inventory for immediate shipment.
• Q: Which carriers do you use for shipping?
  A: We ship via FedEx, UPS, and DHL to ensure fast and trackable delivery worldwide.
