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, sortingsystems, interfacingto 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.
CAUTION: Read all safety warnings before installing, making connections, or servicing the
Discrete I/O PCB. Failure to comply with these warnings could result in personal injury
and/or property damage. Retain all instructions for future reference.

INTERFACE INSTALLATION
CAUTION: THE INSTALLATION AND WIRE CONNECTIONS TO THE DISCRETE I/O
BOARD SHOULD ONLY BE DONE BY AUTHORIZED AND QUALIFIED
PERSONNEL, SUCH AS AN ELECTRICIAN.
WARNING: BEFORE MAKING CONNECTIONS TO THE RELAY TERMINALS,
POWER OFF THE SYSTEM AND REMOVE ALL EXTERNAL AC POWER
CONNECTIONS.
WARNING: WHEN MAKING ANY LINE VOLTAGE CONNECTIONS TO THE
DISCRETE I/O, FOLLOW NATIONAL ELECTRICAL CODE (NEC) OR LOCAL
AUTHORITY WIRING STANDARDS AND SAFETY PRACTICES.
For TD52P:
1. Separate the indicator from the base by loosening load cell cable male connector.
Remove the interface option cover.
2. Break off the rib of the accessory cover as shown.

4. Disassemble the cable gland by loosening the cap nut and removing the rubber seal.
Pass the relay output through the cap nut, then spread the rubber seal and place it over
the cable. Now pass the cable through the body of the cable gland.
5. Install the relay board. Secure it with 2 screws. (Note: boss post is 5 and 7.)
Connect the cable to the relay board 12 pin connectors. Put the relay cable through the
M25 hole. Connect it to the 3 pin and 6 pin connectors.

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 mm2) maximum
24 AWG (0.205 mm2) minimum
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:
Notes:
1. Dry contact relays.
2. Relay contact rating:
AC: 24-250 VAC, 1.0 AMP. INTO resistive load.
DC: 5-45 VDC ,1.0 AMP. INTO resistive load.
Maximum switching power: 250VA, 30 W.
3. Maximum output circuit current = 3 AMPS.
4. All inductive loads must be suppressed.
5. Wire size: 18 AWG (0.832 mm2) Maximum
24 AWG (0.205 mm2) Minimum
