About 1746-IB16
The AB 1746-IB16 is a medium density DC input module that is used
to interface with signal devices that delivers a signal voltage
range of 10-30VDC towards each of the input channel of the module.
This module features Sixteen (16) input channels, rated for nominal
input voltage of 24VDC, grouped into One (1) input group, having a
single common terminal. This input module is mounted to any
available I/O slot of the 1746-Chassis and draws backplane current
of 0.05 A @ 5VDC.
The 1746-IB16 supports sinking wiring configuration only. It cab
used to interface with electrical components such as switches
including limit, proximity, pushbutton devices as well as auxiliary
contacts of relays, contactors and other electronic devices. Each
of the input channels of the 1746-IB16 exhibits a common signal
delay duration of 8 ms for both On and OFF transitions, with
maximum OFF-state voltage of 5VDC and maximum OFF-state current of
1 mA while the module’s nominal input current is 8 mA @ 24VDC.
The number of installation instances of the 1746-IB16 varies
according to the SLC500 CPU installed. Specifically, depending on
the number of I/O supported by the CPU memory. This module may also
be installed locally, along the rack where the SLC 500 CPU is
installed or in a Distribute I/O chassis, along a 1746
Communication adapter such as Remote I/O (RIO) and Ethernet adapter
modules. This module comes with status LED indicators that provided
indications to the actuation of each of the input channels for
simplified monitoring and troubleshooting. It also has a Removable
Terminal Block that enables ease of termination and module
replacement.
The 1746-IB16 has a maximum signal delay time of 8ms for both ON
and OFF transitions while the module’s maximum drop voltage of 5V
DC in the OFF state. It has a maximum leakage current of 1mA and
has a nominal input current of 8mA at 24V DC across the entire
module.
The 1746-IB16 has a net heat dissipation of 0.22W on each input
point and a total heat dissipation on the entire module is 3.6W.
Its operating temperature ranges between 0 and 60 °C (32 and 140
°F) in a surrounding with 5-95% relative humidity, and when not in
use, should be stored at a temperature range between -40 and 85 °C
(-40 and 185 °F). The 1746-IB16 has a tested operational shock
rating of 30G and is designed to withstand an operational vibration
of 2.5G at 57-200 Hz operational frequency. It has a NEMA standard
ICS 2-230 rated noise immunity and is UL-A196, CSA, and C-UL Class
I, Division 2 Hazardous Environment-rated. It offers
Electro-optical isolation tested at 1500V, between input terminals
and control logic, and is UL, CSA, and CE-certified.
