Digital Input Output Module for Zone 1
Series 9470/32
4.1 Function
Application range
The digital input output module is used for connecting up to 16 intrinsically safe digital
signals to the IS1 Remote I/O system.
It is approved for use in hazardous areas of Zones 1, 2, 21 and 22 and in safe areas.
Mode of operation
All channels can be parameterised in pairs as input for connection of passive contacts or
NAMUR proximity switches (EN 60947-5-6) or as output for connection of low power
solenoid valves. Up to 8 inputs can be used as frequency inputs or counters up to 20 kHz,
in the "Rotation direction recognition" and "Forward/backward counter" operating mode
up to 4 inputs. The Ex i inputs or outputs are short-circuit proof and galvanically separated
from the system.
4.2 Device Design
The type 9470/32 digital input output module is a compatible replacement for
series 9470/12, 9470/22 and 9475/12-08-41 IS1 Remote I/O modules.
