PROGRAMMABLE CONTROLLERS
HIGH-DENSITY INPUT MODULE
WITH STATUS INDICATORS
GENERAL DESCRIPTION
The High-Density Input module can be utilized in an 1/O
Rack, in any of the I/O slots in a Model 60 Central Processor Unit (CPU), or a Series Six Plus CPU to provide a
compact, optically-isolated interface between the Series
Six backplane I/O bus and Field Digital Circuitry (TTL
mode) or input devices (10-50 V mode). The HighDensity Input module features and benefits are summarized in Table 1.
This module provides 32 inputs divided into four groups
of eight inputs each. All 32 inputs (four groups) are normally updated in the course of one I/O scan.
(active high). Th e placement of a second jumper allows
the data being sent to the CPU to be inverted
(complemented) or non-inverted. Two Light-Emitting
Diode (LED) indicators identify the selected modes. A
third jumper selects the voltage level of the user power
supply: 5 volts or 10 to 50 volts. When operating in the
TTL mode, the 5 V power supply must be used. DualIn-line Package (DIP) switches on the circuit board allow
the selection of 50 microsecond or 10 millisecond time
delays on an individual basis for each input. Hysteresis of
approximately 10% of supply voltage provides better
noise immunity even with the filter switched off.
There is a common ground (or return) point provided for
all 32 input points.
Refer to figure
specifications.

By placement of a jumper on the circuit board, the user
can select the input data to be sink (active low) or source

INSTALLATION
The High-Density Input module can be installed in an l/O
Rack in a Model 60 CPU Rack or in a Series Six Plus CPU
Rack. Before installing the module, the Dual-In-Line
Package (DIP) switches immediately behind the card slot
on the rack backplane should be set to reserve 32 consecutive input points in the Input Status Table of the CPU. For
specific DIP switch settings, refer to figure 3.
If input connections for 10 to 5OV modes shown in figures
6 and 7 are used, a closed switch turns the input ON; an
open switch turns the input OFF. In the absence of user
power, all inputs will appear to be in the OFF state.
It is recommended that the extraction/insertion tool furnished with the CPU be used to remove or install the circuit boards. With the board in place in the rack, the edge
connector on the faceplate should be slipped over the circuit board so that proper contact is made. The faceplate
can then be secured to the rack using the thumbscrews at
the top and bottom.
The circuit-board jumpers must also be set to configure
t h e m o d u l e t o o p e r a t e in t h e d e s i r e d s y s t e m
configuration. For example: sink or source, invert or noninvert, TTL or lo-50 volt inputs. Refer to figure 2, User
Items and appropriate figure 5, 6 or 7.
Refer to figures 4 for a typical symbolic input circuit.
NOTE
Refer to figures 5, 6 and 7 for Typical User Input connections to this module. In the TTL mode of operation, the
low (negative) side of each of the TTL inputs must be returned to the Module Common (COM) terminal Pin 34.
Jumper JP3 must be set correctly for
the voltage in use. See figures 5, 6,
and 7. Failure to set JP3 to the correct
position may prevent module from
operating.
The ON state of an input point, as defined in figure 1, results in a “1” being loaded into the Input Status Table
with the module in the non-inverting mode; an input in
the OFF state results in a “0” being loaded into the Input
Status Table.
NOTE
