MCE HC-RB4-VFAC Relay Board Elevator Control Interface

The HC-RB4-VFAC relay board is a key component in Motion Control Engineering (MCE) elevator control systems, specifically designed for variable frequency AC (VFAC) drive applications. This board functions as an interface between the controller’s logic circuits and high-voltage field devices, managing signal switching for critical operations such as motor control, door functions, and safety circuits. It plays an essential role in translating low-voltage control signals into actionable outputs within the elevator system.

This unit is New Old Stock (NOS) and has never been installed, providing a clean and unused option for maintaining or restoring compatible MCE VFAC control systems. The HC-RB4-VFAC is part of the HC series control architecture and is typically used alongside processor and I/O interface boards, supporting coordinated system performance. Its relay-based design ensures dependable operation in demanding elevator environments.
