Technical data of analog inputs

Number of channels per module, oper. mode"12 bits" 8

Number of channels per module, oper. mode "8 bits" up to 16

Configurability oper. mode "12 bits" ±10 V, 0...20 mA (each channel can be configured

individually)

Configurability oper. mode "8 bits" 0...10 V, 0...20 mA (channels can be configured in

pairs)

Signalization of input signals see diagnosis

Input resistance per channel voltage input > 100 kΩ

current input approx. 330 Ω

The current input has a self-protecting feature. If the current gets too high, the current input shunt is switched off and

the value for "overflow" is output. Re-activation is attempted again in increments of approx. 1 second to facilitate the

correct measurement as soon as the current regains acceptable limits.

Time constant of the input filter 470 µs for voltage,

100 µs for current

Conversion cycle (over 8 inputs + 8 outputs) 8 ms

Resolution range ±10 V oper. mode "12 bit" 5 mV (11 bit plus sign)

range 0...20 mA oper. mode "12 bit" 5 µA (12 bit without sign)

Resolution range 0...10 V oper. mode "8 bit" 40 mV (8 bit without sign)

range 0...20 mA oper. mode "8 bit" 80 µA (8 bit without sign)

Relationship between input signal and hexcode -100 %...0...100 % = 8008H...0000H...7FF8H

operating mode "12 bits" (-32760...0...32760 decimal)

Relationship between input signal and hexcode 0...100 % = 00H...FFH

operating mode "8 bits" (0...255 decimal)

Voltage inputs not used can be bridged to increase noise immunity

Current inputs not used are low in ohms, can remain open
