Thank you for choosing this Eaton Logic Controller (ELC) series has
controllers with 10 to 40 embedded I/O points. To ensure proper installation,
operation and maintenance, please read this instruction sheet carefully
before installing ELCB-PB.
This instruction sheet provides only information on the electrical
specification, general functions, installation and wiring. It should be read
and understood before attempting to install or use the unit.
Further information can be found in the ELC series Programming
Manual.
These are OPEN TYPE controllers and therefore should be installed in
an enclosure free of airborne dust, humidity, electric shock and vibration.
Your application may require that the enclosure be locked to prevent
non-maintenance staff from operating the controller (e.g. key or specific
tools that are required for opening the enclosure) in cases where danger
and damage to equipment or personnel may occur.
DO NOT connect AC power to any of the DC I/O terminals; serious
damage may occur. Check all wiring before switching on power.
Ensure that the ground terminal is correctly grounded in order to
prevent electromagnetic interference.
This manual is subject to change without notice.

Installation
Please install your controller in an enclosure with sufficient space around it
to allow proper ventilation, as shown in the figure.
DIN Rail Mounting: When mounting the
ELCB to 35mm DIN rail, be sure to use the
retaining clip to stop any side-to-side
movement of the ELCB and reduce the
chance of wires becoming loose. The
retaining clip is at the bottom of the ELCB.

- 4 -
To secure your controller to the DIN rail, pull the clip down, place it onto
the rail and gently push the clip up. To remove the ELCB, pull the
retaining clip down with a flat screwdriver and gently remove the ELCB
from DIN rail.
Wiring
1. Use 12-24 AWG single-core bare wire or multi-core (stranded) wire for
the I/O wiring. The ELCB terminal screws should be tightened to 3.80
kg-cm (3.30 in-lbs) using 60/75°C copper conductor only.
2. DO NOT wire empty terminals. DO NOT place input signal wires and
power wires in the same wiring circuit.
3. DO NOT drop tiny metallic conductors into the ELCB while installing the
controller or other equipment.
Power Supply
The input power supply for the ELCB-PB controller isAC. When operating
ELCB-PB, please note the following points:
1. The range of the input voltage should be 100 ~ 240VAC. The power
supply should be connected to L and N terminals. Please note: wiring
110VAC or 220VAC to a +24V output terminal or to digital inputs will
result in serious damage to the ELCB.
2. Use 1.6mm wire (or larger) for the grounding ELCB.
3. Apower loss for less than 10ms will not affect the operation of the ELCB.
However, longer power loss or a sustained drop of power supply voltage
will stop the running of the ELCB, and all outputs will turn “OFF”. When
proper power is restored, the ELCB will resume operation. (Please keep
this in mind when you use latched auxiliary relays and registers in your
ELCB program.)
4. Please refer to the electrical specification table for the maximum output
of the +24V power supply output terminal for each controller. DO NOT
connect other external power supplies to this terminal. Every input point
requires 5 to 7mA to drive when powered by rated voltage 24V to 30V
(i.e. 16 input points will require 80 to 112mA to drive). The +24V input on
ELCB-PB is only for digital input points; other external loads are not
supported.
Safety Wiring
In an ELCB control system, many devices are controlled at the same time,
and actions of any device could influence another device, i.e. breakdown of
any device may cause the breakdown of the entire control system.
Therefore, we suggest you wire a protection circuit at the power supply
input terminal. See the figure below.

The output of the transistor module is “open collector”. If Y0/Y1 is set to pulse
output, the output current has to be 0.05 ~ 0.5A to ensure normal operation of the
output.

2. Diode + Zener suppression: Used with larger loads, and for rapidly switching
applications.

Note: 1. Terminal resistors are suggested to be connected to the master, and the last
slave, with resistor value of 120.
2. To ensure communication quality, please wire using double shielded twisted
pair cable (20AWG).
3. When voltage drop occurs between the internal ground references of two
systems, connect the systems with Signal Ground point (SG) for achieving
equal potential between systems so that a stable communication can be
obtained.
