About 1746-OW8
The AB 1746-OW8 SLC 500 Digital Input Module comes with Eight (8)
outputs. This module has a voltage category of AC/DC Relay. The
operating temperature is -25-60 deg. Celsius (-13-140 deg.
Fahrenheit) and the nonoperating temperature is -40-85 deg. Celsius
(-40-185 deg. Fahrenheit) with a relative humidity from 5-95%
without condensation. The operating vibration of this module is 2g
at 10-500 Hz and the operating shock of this module is 30g. The AB
1746-OW8 has a maximum heat dissipation of 3.7 Watts with 0.138
Watts per point.
The AB 1746-OW8 Digital Input Module has an operating voltage range
of 5-125V DC and 5-265V AC at 47-63 Hz. The backplane current at 5V
DC of this module is 85 mA. The backplane current at 24V DC of this
module is 90 mA. The AB 1746-OW8 is supplied as open-type
equipment. The 1746-OW8 is intended for use in industrial
environments. This module should be installed in an environment
with a pollution level no higher than Pollution 2 (as defined in
the EN / IEC0664-1 publication) when applied in a Zone 2
environment. The enclosure should be accessible only by means of an
appliance or tool. Do not disconnect equipment unless the power has
been removed. Do not disconnect the equipment if the area it is in
is dangerous. If this is disregarded, a dangerous electric arc will
be created.
The AB 1746-OW8 is an Eight (8) channel relay output module made by
AB that is used with SLC 500 Programmable Logic Controller (PLC)
platform. It is specifically compatible with fixed or modular style
hardware for use with SLC 5/01, SLC 5/02, SLC 5/03, SLC 5/04 and
SLC 5/05 controller.
Use this module with operating voltage categories of 5 -125 VDC and
5 - 265 VAC. This module is divided into Two (2) groups with 4Four
(4) channels per group to allow operation with different or same
voltages. Surge suppression devices may be installed to maximize
the module’s designed operating lifespan.
Configure this module using RSLogix 500 programming software. Aside
from SLC processors, this module is compatible for use in remote
I/O topology. When used in Remote I/O chassis, slot 0 of the
chassis is reserved for an SLC 500 communication adapter. Other
slots are compatible for this module.
With the use of the 1746-OW8, the need of interposing relays may be
eliminated. Interposing relays are typically used for operation
with different voltage category. As this module already support the
mentioned capability, the need for interposing circuit is
eliminated, saving panel space and increasing cost effectiveness.
This module has similar signal delay rating of 10.0 ms for ON and
OFF transitions at maximum resistive load. This module is certified
for Class 1, Division 2 operation. The continuous current per
module is 16.0 Ampere AC with 8.0 A per group. It occupies single
slot of the chassis regardless of the installation location.
