About 1746-IB32The AB 1746-IB32 is an SLC 500 discrete input module. This module
operates at a nominal voltage of 24VDC and at a voltage range of
15-30V DC @ 50 °C (122 °F) or 15-26.4V DC @ 60 °C (140 °F). This
module is typically used to interface electrical devices such as
Switches, Sensors, Auxiliary contacts and other binary or ON/OFF
devices. Up to Thirty-Two (32) input signals may be wired to this
module via the embedded 32 input module channels.
The 1746-IB32 is a single slot module that is configured using the
RSLogix 500 programing software. It is compatible for use with any
SLC 500 processor, ideally with the SLC 500 Modular Style hardware.
It supports being installed locally, along the controller or to an
expansion I/O rack or to a Remote I/O chassis along an SLC 500
communication adapter. It directly installs to any available slot
of the 1746 chassis except slot 1 which is reserved for the SLC 500
controller.
The 1746-IB32 has a backplane current draw of 50 mA at 5VDC with
maximum Off-State Input voltage of 5VDC, Nominal Input Current of
5.1 mA @ 24V DC, maximum Off state input current of 1.5 mA with
typical signal delay of 8 ms for both ON to OFF and OFF to ON
signal transition.
When installing the module, ensure that the power is removed from
the chassis as this module does not support Removal and Insertion
Under Power (RIUP). It comes with a removable terminal block that
permits wiring remote to the module as well as simplified
maintenance as the RTB permits insertion to another module of the
same type.
The 1746-IB32 offers isolation from the backplane tested at 1500
Volts AC for 60 seconds between the backplane and the I/O and it
has a 1500 Volt AC dielectric withstand. The minimum voltage across
its circuit in the ON state is 15.0 Volts DC and in its OFF state,
it has a maximum voltage drop of 5.0 Volts DC and a maximum leakage
current of 1.5 mA. The 1746-IB32 module has a maximum signal delay
time of 3ms across its inputs in the ON and the OFF mode and it has
an overall nominal input current of 5.1 mA at 24 Volts DC nominal
voltage. The 1746-IB32 has an operating temperature bracket between
0 and 60 degrees Celsius (32 and 140 degrees Celsius) at 5 to 95%
non-condensing humidity and it has an operational vibrational
withstand of 1G at 5 to 200 Hertz and a shock rating of 30G. |
