General

Capacitance input / case 3.2 nF

Operating temperature – 20 to + 50 °C

Storage temperature – 40 to + 85 °C

Humidity max. 95% RH, non condensing, up to 40 °C

Isolation voltages Input-Output 1000V Basis isolation

Connections ISO AMP MODULE

Supply voltage 15 - 30 V DC, max 75 mA.

2 pole terminal block To connect the external supply voltage.

15P female D-connector To connect the module to a programming source.

15P male D-connector To connect the module to the power supply.

0 - 5 V
0 - 5 V or 0 - 10 V selectable

200 kΩ
200 kΩ for 5 V input, 400 kΩ for 10 V input

100 Ω / max. 4 mA
1 Ω / max. 4 mA

max. 75% RH, non condensing, up to 50 °C

Input-Case 1000V Basic isolation

The four analog channels are factory-calibrated within 0.1 % for 5 V input and output voltages.
Selecting a 10 V input and/or output without re-calibrating can introduce an extra full scale error of 0.1 %.
Offset, full scale error, non-linearity and temperature coefficient have to be added to the specifications of the power supply.
