The MCB-7 is a microprocessor-based electronic time relay designed for multi-purpose timing applications. It offers four selectable operating modes and a wide adjustable time range from 0.1s up to 30h, accommodating short-cycle process control as well as long-interval timing such as ventilation or lighting sequences.

The slim, narrow DIN-rail body fits compact distribution panels, and the universal 24-240V AC/DC supply allows the same unit to be specified across many control systems. A single changeover output rated 8A/2000VA at Cosφ=1 switches typical control loads, contactors, and small motors.

Key Features

• Microprocessor-based timing with four selectable operating modes
• Wide time range from 0.1s to 30h

Caution: Operating voltage must rise to the indicated value in less than 1 second. Do not use with a generator.

Safety: Disconnect all power before installing. Do not remove the front panel while the device is connected. Clean only with a dry cloth — no solvents. Verify correct terminal connections when wiring. Service only by a qualified electrician. The device is for panel mounting only. Protect upstream with a Type F fuse rated 1A.
