USER’S MANUAL VER.1.3
C55 DUAL 25A RELAY BOARD Rev. 3.1

OVERVIEW

This board serves as a basic dual relay board with two 25Amp electromechanical relays. Delay on activation or on deactivation signal can be configured. Multiple boards can be daisy chained for activation several relays simultaneously.
This version can be easily mounted on control boxes using DIN rails

FEATURES

  • Two 25 Amp. Electromechanical relays with NO and NC positions.
  • Two RJ45 connectors for Input and output signals. To allow daisy chain connecting to 4 boards.
  • Screw-On connections for all terminals (input signal and relay contacts).
  • Indicator LEDs for relay status.
  • User-configurable delay on activation or on deactivation for each relay.
  • Three Dipswitch-selectable delays (1, 2.5 and 5 seconds).
  • Din Rail Mountable. NEW.
  • Pluggable Screw-On Terminals. NEW.

SPECIFICATIONS

Power Requirements.
It requires a 12VDC@200mA external power supply to operate.
Note : For cascade connection are required 400mA for each C55 to connect

WARNING
Check the polarity and voltage of the external power source and connect the 12VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board, and/or the power source.
