4 Channel Programmable Sequential Controller Relay Module

Highly flexible 4 channel programmable sequential relay controller module. Ideal for creating complex multistep bespoke control sequences. It offers the following features:

• Program each channel with up to 240 instruction STEPs
• Choice of three output states for each STEP:
• Activate Relay
• Deactivate Relay
• EXTernal - set relay according to status of the input
• Duration of each STEP can be set from 0.5 Sec and 100 Minutes
• Each channel can be programmed independently
• Programs are stored in non-volatile memory

Each channel has an External Input for connection to a contact closure (e.g. push/slide switch, relay, etc). When the program reaches a STEP set to EXTernal it will read the status of that channels EXTernal Input and Activate the corresponding output relay if the contacts are closed or Deactivate it if the contacts are open.

Programmes can be deleted or modified as required using the LCD display and push buttons on the display board.
