DC (10-30V) Input Module
Cat. No. 1771-IBN
Installation Data
To The Installer
This document provides information on:
important pre–installation considerations
power supply requirements

connecting the wiring
using the indicators on the module for troubleshooting
module specifications
Pre-installation
Considerations
The 1771–IBN dc input module is a sink input and requires a source
output. A sink input provides a path to ground and a source output provides
a positive voltage path.
You must use this module in a 1771-A1B, -A2B, -A3B, -A3B1, -A4B or
later 1771 I/O chassis. Refer to the table below for processor compatibility.

Mini-PLC-2/02 (cat. no. 1772-LZ, -LZP)
Mini-PLC-2/16 (cat. no. 1772-LX, -LXP)
Mini-PLC-2/17 (cat. no. 1772-LW, -LWP)
PLC-5/15, Series B and later (cat. no. 1785-LT)
Remote (with a 1771-ASB PLC-2/20 (cat. no. 1772-LP2)
remote I/O adapter)
PLC-2/30 (cat. no. 1772-LP3)
PLC-3 (cat. no. 1775-L1, -L2, -L3, -L4)
PLC-3/10 (cat. no. 1775-LP4, -LP8)
PLC-5/15, Series B and later (cat. no. 1785-LT)
Do not place this module in the same I/O chassis as the 1771–IX
thermocouple module. You can use this module in the same chassis as the
1771–IXE thermocouple module.
This module has input filtering to limit the effect of voltage transients
caused by contact bounce and/or electrical noise. Specifications for input
filtering are listed in the specifications at the end of this document.
Installation Data
DC (10 - 30V) Input Module
(Cat. No. 1771-IBN)
Power Supply Requirements
The controller or I/O chassis power supply, connected through the
backplane of the I/O chassis, powers the logic circuitry of the dc input
module. The maximum current drawn from this supply is 280mA.
Installing Your Module
In this section we tell you how to initially handle your module, key your
I/O chassis, install your module and make your wiring connections.
Initial Handling Procedures
ATTENTION: Remove power from the 1771 I/O chassis
backplane and wiring arm before removing or installing an I/O
module.
Failure to remove power from the backplane or wiring arm
could cause module damage, degradation of performance, or
injury.
Failure to remove power from the backplane could cause
injury or equipment damage due to possible unexpected
operation.
The input module contains components which can be damaged by
electrostatic discharge. The module is shipped in an electrostatic shielded
bag for protection. Follow the handling procedures outlined below to guard
against damage to your module.
Touch a grounded object to discharge yourself before handling the
module.
Do not touch the backplane connector or connector pins.
If you configure or replace internal components, do not touch other
circuit components inside the module. If available, use a static–safe
work station.
When not in use, keep the module in its static–free shield bag.
Keying the I/O Chassis
Use the plastic keying bands, shipped with each I/O chassis, to key your
I/O slots to accept only this type of module. Place the keying bands on the
chassis backplane between:
14 and 16
18 and 20
Slots on the rear edge of the circuit board are matched to these slots to
allow insertion of this type of module. You can key any connector in an I/O
chassis to receive this module except for the leftmost connector reserved
for adapter or processor modules.

DC (10 - 30V) Input Module
(Cat. No. 1771-IBN)
Inserting the Module Into the Chassis
1.
Position the module so that the circuit board on the rear of the module
lines up with the top and bottom card guides in the chassis.
2.
Slide the module into the chassis.
3.
Press firmly to seat the module in the chassis backplane connector.
4.
Swing the module locking latch down into place over the front edge
of the module.
Connecting Wiring to the Module
You make connections to the module through the field wiring arm cat. no.
1771–WN. The arm pivots on the I/O chassis to connect with terminals on
the front of the module and acts as a terminal strip. The wiring arm allows
the module to be removed from the chassis without disconnecting wiring.
1.
Make certain all power is removed from the module before making
wiring connections.
2.
Swing the wiring arm up into position on the front of the module. The
locking tab on the module will secure it into place.
3.
Make your connections to the field wiring arm as shown in Figure 1.
(Use the label on the front of the wiring arm to identify your wiring.)
ATTENTION: The field wiring arm terminal identification
number is not the same as the number of the bit which controls
that output.

I/O Module Groups
Each module condenses two full module groups (32 inputs) into each I/O
chassis slot. For example:
Module group 1 = inputs 00 through 17
Module group 2 = inputs 00 through 17 (module group 2
represents the second set of inputs).
In Figure 1, terminals 1 through 20 represent module group 1, with
terminals 9, 10, 19 and 20 dc common. Terminals 21 through 40 represent
module group 2, with terminals 29, 30, 39 and 40 dc common.
