About 1746-OA16
The AB 1746-OA16 is a Digital AC output module designed for use
with the SLC500 controller family. This output modules provides
120-240VAC nominal voltage output with voltage range of 85-264VAC
at a frequency of 47-63 Hz.
This module is a Triac output module that is configured using the
RSLogix 500 programming software. It may be installed as a local
and remote I/O module of any SLC500 Programmable Logic Controllers
(PLC) processor or CompactLogix and ControlLogix Programmable
Automation Controllers (PAC). There is no limit to the number of
installation instances of this module as long as the system power
supply is capable of supplying the required current of each module
installed in the same chassis. Specifically, the 1746-OA16 has a
Current draw of 0.316 A. This module occupies a single slot of the
controller chassis and consumes 16-bit I/O memory.
The 1746-OA16 comes with Two (2) output groups with each group
having Eight (8) channels. Each channel of this module has an
output Current of 0.50 A @ 30 °C (86 °F) and 0.25 A @ 60 °C (140
°F) with continuous output per module of 8.0 A @ 30 °C (86 °F) and
4.0 A @ 60 °C (140 °F). It has an On-sate voltage drop of 1.50V @
0.50 A and surge Current per point of 10.0 A for 25 ms while the
module’s load Current is 10 mA. The 1746-OA16 has an ON signal
delay of 1 ms and OFF signal delay of 11.0 ms with OFF-state
leakage Current of 2 mA.
The 1746-OA16 comes with removable terminal blocks that eliminate
the need to disconnect wires when replacing any of the modules. The
1746-OA16 also includes filter circuitry and optical coupling for
signal noise reduction. The 1746-OA16 module’s output values can be
accessed by SLC 500 processors using Ladder Logic. Troubleshooting
is made easier with the LED indicators that show output status
values. The SLC 500 system uses a sharing-based hardware platform
which includes several combinations of digital and analog I/O,
saving costs and space. The 1746-OA16 is intended for use in an
environment with a 0 to 60 degrees Celsius (32 to 140 degrees
Fahrenheit) operating temperature range and 5 to 95% noncondensing
relative humidity.
