CIO DESCRIPTION

Name Type Description

CIO ANI Analogue

input

Analogue differential input for small voltage, current and resistance

measuring It includes differential amplifier with adjustable power

1 to 10000. Exact current source 0.1 to 3 mA can be used to measure

resistance. Configuration of the input signals, amplification

and current source is carried out through resistance net. Presence

of the input signal relevant to A/D converter working range

is signalled by LED on the front panel. Input circuits are protected

against short-time overvoltage by suppressors and against the long-

time one by reverse fuse.

Ranges of the measured values:

U 1V, U 2V, U 5V, U 10V, U 20V

I 5mA, I 10mA, I 20mA

Pt100 100

C, Pt100 200

C, Pt100 500

Resistance 100 to 50000 Ohm (METRA transmitter)

CIO OPI Binary

input

One galvanically-separated digital input for AC/DC signals up to 30 V,

on high voltage brackets up to 350 V. It includes bipolar optoelement

that enables processing 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 overvoltage by suppressors and against the long-time one by

a reverse fuse.

Insulation capacity of the galvanic part is 5000 V.

Input DC voltage – 30 V

Input AC voltage 3 – 30 V rms

Input AC voltage, high voltage input 150 – 350 V

CIO REO Binary

output

One relay output. It includes a relay with one switch contact. Switch

on/off contact is linked separately, common contact twice

(C marking). The presence of a control signal is LED signalled.

Insulation capacity of the galvanic part is 5000 V.

Maximum permanent voltage 400 V rms

Maximum permanent current 5 A rms
