Description
The OE355 - 4 Analog Output Modular
Expansion Board is used in conjunction
with the OE352 - 2 Slot Modular I/O
Base Board or the OE353 - 4 Slot
Modular I/O Base Board. The OE355
Expansion Board provides (4) 0-10 VDC
analog outputs for driving actuators,
valves etc.
For easy wiring the OE355 – 4 Analog
Output Modular Expansion Board con-
nects to the OE352 or OE353 Modular
I/O Base Boards by means of an inte-
gral connector arrangement. Power is
supplied to the OE355 - Expansion
Board through this connector, simplify-
ing installation and connection. Jumpers
are also provided on the OE352 and
OE353 Modular I/O Base Boards for
addressing of the OE355 - Expansion
Board(s).
The analog outputs are designed to
drive a 1K Ohm minimum load. All out-
puts have a resolution of 1.6% or (.16
Volts).
