Discrete Inputs/Outputs
A wide range of discrete Input/Output modules are available to meet your needs in the best possible way. These modules differ from one another in their:
Characteristics
Description
Modularity
8, 16, 28, 32 or 64 channels.
Type of inputs
  • modules with direct current inputs (24VDC, 48VDC),
  • modules with alternating current inputs (24 VAC, 48 VAC, 110 VAC, 240 VAC).
Type of outputs
  • modules with relay outputs,
  • modules with direct current static outputs (24 VDC / 0.1 A - 0.5 A - 2 A, 48 VDC / 0.25 A - 1 A),
  • modules with alternating current static outputs (24VAC / 130VAC / 1A, 48VAC / 240 VAC / 2A).
Type of connectors
Screw terminal blocks and HE10 connectors allow the connection of sensors and pre-actuators via the TELEFAST 2 prewiring system.

Analog Inputs/Outputs
The range of analog Input and Output modules can meet your main needs. These modules differ from one another in their:
Characteristics
Description
Modularity
4, 6, 16 channels.
Performance and range of signals offered
Voltage/current, thermoelectric couple, multi-range (thermoelectric couple, heat probe, voltage/current).
Type of connectors
Screw terminal blocks or 25-pin SUB-D connectors allow the connection of the sensors via the TELEFAST 2 prewiring system.
