ABB DSAO 110 57120001-AT Current isolation output board

Description

Four channels, resolution 12 bits incl. sign,
0 to ±10 V or
0 to ±20 mA, 0 to ±10 mA,
4 to 20 mA (elevated zero obtained by SW)
galvanic isolation, channel by channel
On-line replacement possible
Note! In general, the electrical connections between
output boards and the process is to be broken before the
board is extracted.
Alternative methods includes:
– Open terminal switches on the connection unit
– Disconnect cable which joins the board an
the connection unit.

General instructions are provided in the adjustment instructions below. The detailed information
for individual circuit boards, for example, location of test terminals, location of potentiometers,
jumpering, function descriptions, and so on is provided in the manual S100 I/O Hardware.
If the potentiometers are not accessible on the front, place the board on an extension board
DSFB 110. On the units which can be adjusted channel by channel, adjust the channels before
the A/D converter.
The following aids are required for the adjustments.
• A reference voltage supply unit, with adjustable output within the range 0 – 10.5 V and
with resolution 0.1 mV. The supply unit is not to have mains noise or hum in excess of
0.1 mV. If no supply unit is available, you can use a battery, a potentiometer and a digital
voltmeter with corresponding resolution.
• An adjustable voltage supply unit with rating 100 V.
• A digital voltmeter for the range 0 – 10.5 V with 0.1 mV resolution, accuracy exceeding
that required for the board by a wide margin.
• An oscilloscope for checking mains noise and hum.
• Precision resistors:
– One of 500 ohm, 0.01%
– One of 300 ohm, 0.01%
– One of 100 ohm, 0.01%.
• An Advant Station 100 Series Engineering Station or
Advant Station 500 Series Engineering Station.
• An extension board DSFB 110
• (A miniature soldering iron).
