The input and output modules, or I/O modules, are the interface between the process station and the peripherials. They are supplied in a range of types, according to their input and output signals:

Input modules:

• R420   16 digital (on/off) inputs for 24 V AC/DC, common ground for all inputs
• R430   32 digital (on/off) inputs for 24 V AC/DC, common ground for 24 and 8 inputs
• R500   8 analogue inputs 0…10 V or 0…20 mA
• R560   8 analogue inputs Pt100, Pt1000, Ni1000, 0…5000 Ohm, 0…10 V, 0…20 mA
• R710   4 pulse counting inputs for dry contact or open collectors, up to 50 Hz, also for load shedding

Output modules:

• R220   12 low voltage relay outputs 250 V / 5 A
• R312   8 triac outputs 24 V AC binary or PWM
• R313   8 triac outputs 230 V AC binary or PWM
• R320   16 open collector binary outputs
• R330   32 open collector binary outputs
• R610   8 analogue outputs 0…10V

Combined modules:

• RCIO
• 8 analogue inputs 0..10 V or temperature sensors Pt100, Pt1000, Ni1000, 4x also 0…20 mA
• 6 analogue outputs 0..10 V
• 8 binary inputs 24 V AC/DC
• 8 low voltage relay outputs 250 V / 5 A.

• RMIO
• 4 analogue inputs Pt100, Pt1000, Ni1000, 2x also 0..10 V
• 2 analogue outputs 0..10 V
• 4 binary inputs 24 V AC/DC
• 7 binary outputs (5x relay 230 V AC, 2x SSR 24…230 V AC)

• MLIO
• 4 analogue inputs Pt100, Pt1000, Ni1000, 0..10 V, or as a DI – for dry contact
• 1 analogue output 0..10 V
• 2 relay outputs 250 V / 5 A.

• RXIO
• 16 analogue inputs 0..10 V or temperature sensors Pt100, Pt1000, Ni1000, 8x also 0…20 mA
• 8 analogue outputs 0..10 V
• 32 binary inputs 24 V AC
• 32 relay outputs 250 V / 5 A.

• MW240-B 
• Small I/O module for flush-box installation, with internal logic for control of 2 light groups or a blinds motor.
• 2 DI for dry contacts
• 2 DO – relay 230 V / 4 A

• MW241
• Same as MW240-B, but solid state relays instead of mechanical relays. The module is used for switching of LED light power supplies, which show capacitive characteristics and  mechanical relays should not be used here.

Compatibility for replacement of older M… modules by new R… modules, IRC controllers and converters is as follows:
