Introduction

The function of the DSJ4 is to enable the easy connection for 4 channels of a load cells and DSC Cards for
communications to a PC or PLC.

Designed to take 4 DSC cards in a single enclosure, the DSJ4 offers a convenient and practical solution to the

installation of digital load cells with platforms, silos and any weighing systems where connection to PC and PLC’s is

an essential requirement of the system.

Supplied as an OEM device 100 x 185mm PCB, it has options for fitting in an IP65 ABS case, or to a DIN rail fixture.

Notes for installation & preparing for use

For the operational and communication requirements of the
DSC card, refer to the DSC User Manual Instructions.
The DSC card is mounted on the main PCB with 3 pillars.
The D type connectors J10 & J11 and the 5 way two-part
connector J9 provide the power connections and the RS485 or
CAN connections. J10 and J11 also provide a ‘daisy chain’
interconnect facility for multiple DSJ4 units.
J5 to J8 are two-part 4 way connectors which provide
connections for the digital input and output. J1 to J4 are 8
way two-part connectors providing connections to the strain
gauge and external temperature sensor.

Connection details are shown on the layout diagram on the
reverse of this sheet.

Cable Screening: It is strongly recommended that all cable
screens are connected.

A green LED L1, marked PWR on the PCB provides an indication
of power.

Link LK1 is used to provide a 120R terminating resistor for
RS485 or CAN connections.
