1INTRODUCTION

The 2620 Sensor Interface unit permits

convenient connection of all kinds of sensor types

to die protection logic units such as OmniLink

MPC controls, System 2600 die protection units,

or even third party units. Sensors and probes

installed in or near the die are connected to the

Sensor Interface which also provides sensor

power

The Sensor Interface is designed to be located

near the die to facilitate die changes, setup, and

troubleshooting. It permits quick connection of

individual sensors via industry standard M12 4

pin connectors (also known as Micro-DC or

Eurofast connectors) or of all sensors at once via

an optional Quick Connect Receptacle (Link or

customer supplied).

1.1 Features

•Solid state sensors (NPN or PNP), spring probes, and mechanical sensors may be used as inputs to

the Sensor Interface.

•Up to 8 sensors can be powered and passed through to a die protection unit via the internal

connectors (usually through a Link or customer supplied bulk quick connection).

•6 M12 4 pin sensor connectors (also known as Micro-DC or Eurofast connectors) are provided on

the face of the unit for connecting individual sensors to channels 1 - 6.

•3 Banana plug/binding post connectors are provided on the face of the unit for connecting grounding

spring probes or mechanical sensors to channels 1 - 3.

•No configuration is necessary to select sensor type. This Sensor Interface is designed for die

protections units that can select NPN or PNP sensors on their own and so passes the sensor signal

directly through.

•The Sensor Interface is powered from 115 to 230 VAC and provides 24 VDC @ 0.5 Amp total for

powering sensors. Sensor power is available on each of the front panel M12 connectors, the optional

bulkhead connector, and internal terminal strips.

•In cases where 0.5 Amps is not enough power, the Sensor Interface can be powered by an external

24VDC power supply up to 10 amps.

•The enclosure of the Sensor Interface features a removable bulkhead that can be fitted with a quick

connection receptacle so that only one cable must be plugged in from the die. Link has an optional

standard connector (a 19 pin Turck receptacle suitable for up to 16 channels) or, if desired, a

customer supplied connector can be used.

2INSTALLATION

The dimensions and mounting footprint of the Sensor Interface are shown below in Figure 2. When

mounted to the press frame or other high shock areas, Link highly recommends using the included

shock mounts, which will add about 0.75 inches (19mm) to the depth of the unit.

2.1 Wiring

In the following sections, refer to Figure 3below for the locations of particular connectors and other

relevant features.

2.1.1 Power Wiring

WARNING:

National Codes and standards (NEC, VDE, BSI, etc.) and local codes

outline provisions for safely installing electrical equipment.

Installation must comply with specifications regarding wire types,

conductor sizes, branch circuit protection, and disconnect devices.

Failure to do so may result in personal injury and/or equipment

damage.

The Sensor Interface is typically powered by 115VAC, but can be powered from 100 to 240 VAC OR

can pass through an external 24 VDC supply at up to 10 Amps. An external +24 VDC power supply

might be used in cases where unusually high power draw sensors require more than the 0.5 Amps of

current that is available from the internal power supply of the Sensor Interface. Pull power wires with

the appropriate color code in conduit between the Sensor Interface enclosure and the source of power.

Knockouts are provided at the bottom of the enclosure for this purpose.

When using AC power, use the L1, L2 and PE

terminals. When using an external +24 VDC power

supply, use the +24, GND, and PE terminals. The

table at right shows the usage and specifications of

the connections on the power connector.

WARNING:

The Sensor Interface can be powered from EITHER 100-240VAC OR

+24VDC. Never hook up both AC and DC power at the same time.

When using an external +24 VDC supply, make sure the Power

Jumper (see Figure 3) is removed so that the internal +24 VDC supply

is disconnected.

2.1.2 Internal Sensor Connector Wiring

The Internal Sensor Connector (see Figure

3) is primarily used in conjunction with a

Quick Connect bulkhead connector for

mass die termination or if there are some

sensors that are always present on the

machine regardless of what die is

installed. Link offers (Link PN 109090)

an optional quick connect bulkhead

connector (using a Turck CS-19

connector) that is prewired and ready to

plug into the Internal Sensor Connector.

Figure 4 at right shows how a typical

sensor is wired into this connector. The

unit is supplied with a blank plate for

mounting an existing connector if a

connector system is already in use.

NOTE: If a Quick Connect bulk

connector but there are

inputs that are not actually

connected in the die, then

the corresponding front

panel connectors are still

available for use.

Doc #: L-2600-1020 Page 8 Rev. 01

2.1.3 Front Panel Sensor Connectors

There are 6 M12 4-pin connectors on the front of Sensor

Interface that allow individual sensor to be conveniently

plugged in. These are wired to match the typical industry

standard 2 or 3 wire DC sensors with molded M12

connectors. M12 connectors are also available (Link PN

108046) that can be wired in the field. Figure 5 at right

shows the pinout and typical connection for the M12

connector.

There are also 3 Banana Plug/Binding Post connectors on the

front of the Sensor Interface that are intended for use with

single wire grounding sensors such as Whisker Probes,

Spring Probes, or other mechanical sensors that are

grounding in nature. Note that Pin 2 on the first 4 of the M12

connectors (labeled WP for “Whisker Probe”) is also a

grounding-only input so that such sensors can be tied in that

way as well. For these sensors, it may be necessary to source

more current through the sensor than is required with solid

state sensors in order to maintain good electrical contact. The grounding inputs have extra pull-ups for

this purpose and even more current can be supplied by switching on the corresponding dip switch for

that channel on the door board of the unit (see “Whisker Probe Switches” in Figure 3).

2.1.4 Wiring to the Die Protection Unit

Figure 6 at right shows a close-up of the outputs connector

that must be wired to the Die Protection Unit. Depending on

the number of channels your Die Protection Unit can handle,

it may not be necessary to use all the outputs. Always

connect the ground (“GND” in the figure at right) on the

outputs connector to ground on the Die Protection Unit.

Then O1 through O8 (or however many are needed) can be

connected to the corresponding Die Protection Unit input.
