M1 Universal Sequential Operations Module

The BLOCKsignalling M1 is a universal module designed for sequential operations on model railway layouts. It allows multiple actions to be carried out automatically in a defined order, making it ideal for creating realistic, interactive layouts with minimal manual control. When triggered, the module performs a pre-programmed action such as powering a section of track, operating points, or changing signals. It then waits for a train to be detected by the infra-red sensor or for a timed condition to be met. Once complete, the module sends a “DONE” signal which can trigger additional modules, enabling complex sequences to be created. By linking multiple M1 modules together, a chain of events can be automated, such as moving trains through a fiddle yard, operating points in sequence, or controlling signalling systems. Modules can also be connected in a loop for continuous operation. Key Features Automatically performs pre-programmed actions triggered by input or detection. Two independent relay outputs for controlling track power, points motors, signals, and more. Supports sequential operation by linking multiple modules together. Trigger inputs include push-button, switch, reed relay, infra-red sensor, or another module. Infra-red train detection for precise, automated control. “DONE” output allows chaining modules for complex automation. Multiple built-in programs including fiddle yard control, points operation, signalling, and direction change. Fully programmable universal mode for custom operation sequences. Adjustable timing, delays, and relay behaviour for flexible operation. Compact design with screw terminals for easy wiring. Compatible with OO, HO, and other scales depending on application. Electrical Specifications 12V DC power supply required. Typical current draw: 10mA idle, 50mA with one relay active, 100mA with both relays active. Relay outputs rated up to 1A at 24V DC. Reverse polarity protected (module will not operate but will not be damaged).
