Cebek I-57 (CI057) - 8 Channel Flexible Sequential Relay Controller Module
Cebek I-57 Electronic Module (Pre-Assembled)
Cebek Electronic Modules

The Cebek I-57 offers a choice of 8 sequential step patterns and provides Manual or Automatic operating modes. The relay outputs are rated to switch up to 230vac or 28Vdc. Can be expanded to 256 channels with additional units detailed below.

The step patterns available (demonstrated in the product video) are:

  • sequential counting UP then OFF; REPEAT
  • sequential counting UP with OFF between each step; REPEAT
  • sequential counting UP then back DOWN and OFF; REPEAT
  • sequential counting UP then back DOWN with OFF between each step; REPEAT
  • cumulative counting UP then all OFF; REPEAT
  • cumulative counting UP then back DOWN and OFF; REPEAT
  • cumulative counting UP with OFF between each step; REPEAT
  • cumulative counting UP then back DOWN with OFF between each step; REPEAT

The I-57 has two operating modes.

MANUAL Mode:

  • controlled externally using STEP-UP and STEP-DOWN inputs
  • connect inputs to dry contact closures (e.g. switches, relay contacts) or 5Vdc control signal

AUTOMATIC Mode:

  • uses the internal oscillator to automatically drive the sequences
  • user adjustable output connection duration (relay on time) from 1 to 240 seconds
  • user adjustable interval duration (time between output activation) from 0.3 to 58 seconds

RESET Input: turns off all active relays, restarts sequences from beginning when released. Works in both Manual and Automatic modes.

RELAYS DIP Switch: selects the number of relays used by a sequence e.g. maybe you only want 7 relays to operate or you are using the I-57 with multiple extensions boards and require say 25 active outputs.

CONTROL DIP Switch: selects operating mode and step pattern required.

Expansion Boards

When connected to the optional I-58 (4 channel) or I-59 (8 channel) expansion modules, the I-57 can be expanded to a maximum of 256 channels. Boards are daisy-chained together using the onboard communication connector (use 4-core cable like our Order Code 804.859).

The module includes protection against inverse polarity. LED status indicators for Mode, Function and individual Relay.
