INTRODUCTION

This discrete I/O interface Kit is for use with OHAUS TD52P and TD52XW indicators.
When installed, the system software allows the relay to be programmed in a variety of ways.

BASIC APPLICATIONS

Applications include driving external Over/Accept/Under displays, motor controls for semi-automatic
filling systems, sorting systems, interfacing to industrial PLC systems, etc. The Relay outputs can also
be used as slave relays to drive high power relays in larger systems.
For the setup in each application, please refer to the instruction manual supplied with scale.
Set up the discrete I/O controls as described in the I/O menu section of that manual.

Notes:

CONNECTION

x INPUT
The discrete I/O interface enables other devices such as PLCs to provide the trigger voltage (typically

12 VDC or 24 VDC, maximum 30 VDC) to turn the inputs “on”.
An example of wiring to the inputs with the +V to the common is shown:

Note:

1. Voltage: 5~30 VDC, 10 mA maximum current. Voltage polarity cannot be reversed.

2. Do not bundle input wiring with power wiring or any other high energy cables.

3. Wire size: 18 AWG (0.832 mm
24 AWG (0.205 mm

x OUTPUT
The four dry-contact normally open relay outputs can switch up to 250 VAC or 30 VDC voltages at 1A

maximum.
The relay outputs are not polarity-sensitive since they are dry contact outputs.

An example of wiring to the outputs is given below:

Maximum switching power: 250VA, 30 W.

3. Maximum output circuit current = 3 AMPS.

INTRODUCCIÓN

Este kit de interfaz E/S discreta se utiliza con los Indicadores Ohaus TD52P y TD52XW.
Una vez instalado, el software del sistema permite que el relé se programe en una variedad de maneras.

APLICACIONES BÁSICAS

Las aplicaciones incluyen pantallas «Under/Accept/Over» (por debajo/aceptar/por encima), controles
de motores para sistemas de llenado semi-automáticos, sistemas de clasificación, interconexión con
los sistemas PLC industriales, etc. Las salidas de relé también se pueden utilizar como relés
esclavos para accionar relés de alta potencia en sistemas más grandes.

Para la configuración de cada aplicación, consultar el manual de instrucciones suministrado con la
báscula.
