CI0027 - 2-Channel Sequential Relay Timer Module (1 - 180 Second)

2-channel sequential delay timer relay module with independently settable delay periods from 1 - 180 seconds. Communication I/O connections to daisy chain multiple units. Mains rated relay outputs. Start and Reset switch inputs. Instant-on option.

The module can be activated using the Start Switch input (push-button contact closure) or by selecting the Instant-On option so it initiates on powering up.

On activation Relay 1 turns on for a user-adjustable delay period. On completion, Relay 1 turns off and Relay 2 turns on for a second user-adjustable delay period. Both delay periods are independently settable from 1 - 180 seconds using the onboard potentiometers (header pins allow the use of user-supplied external potentiometers if required).

A Reset Switch input stops the timing sequence, turns off the active relay and returns the module to its initial state.

Each board has a communication input and output that allows several boards to be daisy chained together in series.

The module has no memory function and will always start from the relay 1 position when first activated.

The module includes protection against inverse polarity, indicator output LEDs and screw terminal blocks. Requires external 12V dc power supply (Order Code PSU446 with connector 778.106).

You can use this board for an automatic reversing DC motor setup.
