OVERVIEW
The ”3100i” can, in addition to the analogue inputs, be fitted with a digital
I/O-interface.
This digital board is mainly used in event-counting applications but can also
be used where status or on/off signals must be detected.
INTAB PC-logger software support the use of the relay outputs as alarms.
This card is available in two versions: with or without counters.
A fully equipped card has the following I/O’s:
- 4 digital outputs (relays)
- 8 digital inputs, 6 of which are used as inputs to the counters.

Outputs
Four digital outputs in the form of (relay) contact closures are available. They
find their use as alarms and in simple regulating functions and are as such
supported by the EasyView Pro software.
The relay coils are, to prolong battery life, powered directly by the mains
adapter and not by the internal batteries.
The EasyView Pro PC-logger software supports programming of alarm levels
that can be assigned to these relays.
Digital output status is reflected in channel 32.
The binary sum of active outputs are presented with DO1 as LSB.
