LED on the front panel. Input circuits are protected against short-time
over voltage by suppressors and against the long-time one by a
reverse fuse.
Ranges of the measured values:
U 1V, U 2V, U 5V, U 10V, U 20V
I 5mA, I 10mA, I 20mA

Resistance 100 to 50000 Ohm (METRA transmitter)
CIO OPI 2 Binary
input
A single galvanic-separated digital input used for direct and alternate
signals up to 30V. It includes a bipolar opto-element that enables
processing of both input signal polarities. For AC signal, it includes
integration circuit that provides for direct processing of 50 Hz signal.
Output logical value of the measured signal is LED signalled on the
front panel. Input circuits are protected against short-time over
voltage by suppressors and against the long-time one by a reverse
fuse.
Input D.C. voltage of 3-30V
Input A.C. voltage of 3-30V rms
CIO REO 2 Binary
output
A single relay output. It includes a relay with a single changeover
contact. The changeover contact terminal is separate, common
contact is doubled (marked as C). The LED signals the presence of
the governing signal of the relay.
Maximum constant voltage 230V rms
Maximum constant current 5A rms
