Thank you for choosing this Eaton Logic Controller (ELC). The

ELCM-PH/PA series has controllers with 16 to 40 embedded I/O points and

are expandable using 8 to 16 point digital I/O modules. The maximum

number of I/O points, including those on the controller is 256. ELCM-PH/PA

controllers can be configured with different mixes of digital, analog, and

specialty I/O, to suit a wide variety of applications.

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 controllers (e.g. key or specific

tools that are required for operating 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 properly grounded in order to

prevent electromagnetic interference.

This manual is subject to change without notice.

Installation

Please install the ELCM in an enclosure with sufficient space around it to

allow for proper ventilation, as shown in the figure.

- 6 -

DIN Rail Mounting: When mounting the

ELCM to 35mm DIN rail, be sure to use

the retaining clip to stop any side-to-side

movement of the ELCM and reduce the

chance of wires becoming loose. The

retaining clip is at the bottom of the ELCM.

To secure the ELCM to DIN rail, pull down the clip, place it onto the rail

and gently push the clip up. To remove the ELCM, pull the retaining clip

down with a flat screwdriver and gently remove the ELCM from DIN rail.

Wiring

1. Use 12-28 AWG single-core bare wire or multi-core (stranded) wire for

the I/O wiring. The ELCM terminal screws should be tightened to 4.75

kg-cm (4.12 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 ELCM while installing

the controller or other equipment.

Please attach the dustproof sticker to the ELCM before installing to

prevent conductive objects from dropping in.

Tear off the sticker before running the ELCM to ensure proper

ventilation.

Power Supply

The power input type for ELCM-PH/PA controllers is AC. When operating

ELCM-PH/PA controllers, please note the following:

1. The range of the input voltage should be 100 ~ 240VAC (nominal). The

power supply should be connected to L and N terminals. Please note:

wiring 110VAC or 220VAC to +24V output terminal or any of the digital

input points will result in serious damage to the ELCM.

2. The AC power inputs for the controller and the digital I/O modules should

be ON or OFF at the same time.

3. Use 1.6mm wire (or larger) for the grounding of the ELCM.

4. A power loss for less than 10ms will not affect the operation of the ELCM.

However, longer power loss or a sustained drop of power supply voltage

will stop the running of the ELCM, and all outputs will turn “OFF”. When

proper power is restored, the ELCM will resume operation. (Please keep

this in mind when you use latched auxiliary relays and registers in your

ELCM program.)

5. The +24V output is rated at 0.5Afrom the controller. DO NOT connect

other external power supplies to this terminal. Every input terminal

requires 5 to 7mAto be driven; e.g. the 16 point input will require

approximately 100mA. Therefore, +24V terminal cannot support an

external load that is more than 400mA.

Safety Wiring

In an ELCM control system, many devices are controlled at the same time

and actions of any device could influence another device, i.e. breakdown of

- 7 -

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.

Relay (R) output circuit wiring

○

DC power supply

○

Emergency stop: Use an external switch

○

Fuse: Use 5 to 10A fuse at the shared terminal of output contacts to protect the

output circuit

○

Transient voltage suppressor: To extend the life span of relay contacts.

1. Diode suppression of DC load: Used with smaller loads.

2. Diode + Zener suppression of DC load: Used with larger loads, and for rapidly

switching applications.

○

Incandescent light (resistive load)

○

AC power supply

○

Mutually exclusive output: For example, Y4 and Y5 control the forward running and

reverse running of the motor, forming an interlock for the external circuit, together

with the ELCM internal program, to ensure safe operation in case of any

unexpected errors.

○

Suppressor: To reduce the interference on AC load.

The output of the transistor is “open collector”. If Y0/Y1 is set to pulse output, the

output current has to be 0.05 ~ 0.5Ato ensure normal operation of the output.

1. Diode suppression: Used for smaller loads.

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

applications.

○

Mutually exclusive output: For example, Y3 and Y4 control the forward running and

reverse running of the motor, forming an interlock for the external circuit, together

with the ELCM internal program, to ensure safe operation in case of any

unexpected errors.
