I-55 Electronic Module (Pre-Assembled)
This module has 8 relay outputs that operate sequentially using a choice of manual or automatic triggering. With each trigger signal the module receives, the relays are individually activated (stepped) in sequence. As the next relay activates, the previous relay will turn off and when the last one has activated, the process will start again from the first relay.
In Manual mode the relays are "stepped" by external impulses (a simple contact closure). The sequence advances by one step only regardless of the input duration.
In Automatic mode the relays automatically and continuously step through the sequence (starting from relay 1) when the module is powered up. The "step" time period can be adjusted between about 0.3 and 10 seconds.
A Reset input (contact closure operation) returns the current sequence to the Relay 1 position. It will remain at this position until the Reset input is released.
The module has no memory function and will always start from the relay 1 position when first activated.Specifications
