The IO 2 ( , nput - 2 utput) module from the IKA Laboratory Technology company provides for 8
digital inputs ( TTL-Pegel ) and 8 digital outputs (potential-free relay contacts/make contacts).
,QSXWV
8 independent inputs (with common ground terminal).
Either voltage outputs (0-24V) or direct switching contacts (e.g. limit switches) may be
connected, where voltages < 0.8 V or closed contacts correspond to the TTL-level and
voltages > 2.0 V or open contacts correspond to the TTL level 1 .
Input resistance > 100 k.
The IO module only differentiates between logical 0 and logical 1 input signals. If the voltage is
also to be recorded then the Datacontrol DC2 has to be used.
Activated inputs are shown on the right side of the module.
2XWSXWV
8 independent, potential-free relay contacts (make contacts), each with a switching capacity of
30 V / 1 A.
In order to switch mains voltage or high currents a power switch with a grounding pin is
available as an accessory.
The IO module only transmits output signals between logical 0 and logical 1. If the voltage is to
be displayed as well then the Datacontrol DA2 has to be used.
Activated outputs are shown on the left side of the module.
The 8 inputs or outputs can be activated and selected or evaluated independently of each other.
For safety reasons only low voltages in accordance with EN 61 010 (IEC 1010) may be used in
the input and output voltage range!
