System Description RIO / microLine

RIO Expansion Modules
Digital and analog modules with various numbers of channels
and practical functionality are available for connecting the
periphery. Up to eight modules can be connected in any
combination at one bus node.
The internal bus connection and voltage supply are provided
by integrated slide contacts. The 24 V supply is provided
through external terminals and can be passed from module
to module, or fed separately if more current is required.
Wiring is by the vibration-proof spring-loaded clamping key
system. The modules can be augmented with a terminal
extension with two additional jumper levels.
Digital I/O Modules
with 4, 8 or 16 channels detect and switch control and
position signals from the process level:
• DC 24 V, AC 130/240 V, relay
• Input/output channels isolated from internal bus
• Combination channels can be used as inputs or outputs
• Outputs can be connected in parallel, short-circuit-proof
and overcurrent-protected
Analog I/O Modules
detect 4-channel measured values and pass position signals
to the process level:
• Voltage inputs as differential inputs with ±10 V
• Current inputs as single-ended inputs, range 0/4..20 mA
• Sampling rate 2 ms
• Short-circuit-proof outputs ±10 V or 0..20 mA
RIO Function Modules
The function modules for temperature, counter and axis
control allow data processing to take place directly in the
bus node.
• High-frequency data collection
• Reduced load on field bus
• Reduced load on central PLC
