Universal unit with inputs and outputs, 10 inputs and 8 outputs - IOU3 -108M

EAN: 8595188181884 | Code: 8188 standard


  •  IOU3-108M is a combined actuator equipped with 8 binary inputs, 2 temperature inputs and 8 independent relays with switching potential-free contacts
  •  Binary inputs IOU3-108M are used to connect up to 8 devices with a potentialfree contact (such as switches, buttons, burglar alarms and fire detectors or others).
  •  The unit can be used to read pulses from energy meters with a pulse output.
  •  The temperature inputs support the connection of the following temperature sensors: TC / TZ - 2-wire connection
  •  They are used in cases where it is necessary to measure the temperature, eg floor/space, indoor/outdoor temperature, technological equipment - boiler rooms, solar heating, etc.
  •  The maximum load capacity of the contacts is 10 A / 2500 VA / AC1.
  •  Each of the output is individually controllable and addressable.
  •  The relays are divided into four pairs, where each pair switches its common potential.
  •  The actuator is designed for switching up to eight different appliances and loads via a relay output (potential-free contact).
  •  IOU3-108M in 6-MODULE design is designed for mounting in a switchboard on DIN rail EN60715.
