1.1 O vervi ew
The I/O Module is an external device designed for use with the 320IS and 320IS Plus digital weight indicators. When
placed in the safe area, its fiber optic interface allows it to provide remote functions for indicators in hazardous
environments. The I/O Module provides access to the indicator through two serial ports supporting several physical
standards (RS-232, RS-485, RS-422, and 20mA current loop) and integrating the following I/Os:
•Two isolated 16-bit analog outputs
•Four digital inputs
•Four relay contact outputs
The I/O Module operating parameters are stored in the attached indicator. After both the indicator and I/O Module
are connected and powered up, the module attempts to communicate with the indicator and download
configuration parameters. The peripheries are operated by the indicator, which acts as the master device in the
system.

4I/O Module - Intrinsically Safe
2.3.1 AC Wiring/Installation
The 320IS Plus is to be permanently mounted with a readily accessible disconnect device incorporated in the
building installation wiring. All wiring is to be done in accordance with the National Electric Code (NEC).
2.4 Fiber Optics Assembly
The 320IS Plus is equipped with duplex fiber optic ports for communicating with other devices located in the safe or
hazardous area. It provides electrical isolation and eliminates the use of I/O barriers commonly used in intrinsically
safe systems. The fiber optic wires are plastic; no polishing or further preparation is required. See Figure 2-1 on
page 3 for the location of the fiber optic ports on the 320IS Plus main board.
NOTE: The fiber optic connections between the indicator and the 320IS Plus need to be cross-linked. The optical
output of the indicator should be attached to the input of the 320IS Plus, and the indicator’s input to the module’s
output.
Use the following steps for assembling the fiber optics connectors of the 320IS Plus:
1. Cut off the ends of the fiber optic cable with a single-edge razor blade or sharp knife. Try to obtain a
precise 90º angle.
2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal
micro-lens.
3. Screw the connector locking nut down to a snug fit, locking the fiber in place.
4. Secure duplex fiber optic cable to wire tie mounting button located on I/O Module circuit board (see
Figure 2-1 on page 3) using wire ties included in parts kit.
Figure 2-3. Fiber Optic Connector
2.4.1 EDP and Printer Ports
The indicator communicates with external devices through the 320IS Plus located in a remote location. The I/O
board serves as a gateway with several types of communication interfaces (RS-232, RS-422, RS-485, and 20mA
current loop). The following sections explain how to install and configure the communication interfaces to
establish serial communications with peripheral devices.
2.4.2 RS-232 Communications

To attach a PC or other device to the 320IS Plus’s 20mA ports, select current loop (CL) standard in the indicator
SERIAL menu for the desired port (EDP and/or printer). EDP and printer ports should be configured separately.
See Table 2-6 below for information on connecting 20mA current loop.
2.5 Analog Outputs
The 320IS Plus uses two 16-bit isolated analog output channels with 4-20mAand voltage (0-5V/±5V/0-10V/±10V)
outputs supplied from a DC/DC converter. The output voltage ranges are DIP-switch selectable (see Figure 2-1 on
page 3).Analog output configuration is done via setup mode in the indicator used with the 320IS Plus (see the
applicable indicator installation manual).
the analog output circuitry consists of two identical channels that can be assigned to gross or net weight values. The
analog output can be configured to operate as either current or voltage outputs. the voltage output range is selected
by configuring DIP switches SW1 (1-6) for channel 1 and SW2 (1-6) for channel 2 (see Figure 2-1 on page 3).
Table 2-8. Output Range Configuration
The analog output port is powered by an isolated DC-DC converter. The outputs available on connector CN1 are
listed in Table 2-9 below. See Figure 2-1 on page 3 for the location of CN1 and DIP switches.

2.6 Digital Inputs
The 320IS Plus has four digital inputs that can be used to control pre-defined operations in the indicator. Table 2-10
outlines the various functions for the digital inputs.
Digital inputs are available on connector CN4 (see Figure 2-1 on page 3). All inputs are individually isolated via
opto-couplers. Table 2-10 outlines the pin connections for CN4.
The digital inputs are designed to receive 0-24V/TTL signals on the incoming lines. Care should be taken to apply
the right DC polarity. Pins 9 and 10 (+5V and DGND) can be used to supply power to the digital inputs. Maximum
current draw should not exceed 0.25A.
See the applicable indicator installation manual for information on checking current digital input states.
2.7 Relay Contact Outputs
The 320IS Plus features four relay contact outputs, which default to open. This allows switching of maximum
+30VDC, 5A or 250VAC, 5A for each of the four digital channels.
The relay contact outputs are controlled by user-configurable setpoints. The setpoint values and operating
parameters can be defined in the SETPNT menu of the host indicator. See the indicator installation manual for
information on configuring setpoints.
Table 2-11 show pin connections for CN5 of the 320IS Plus board.
The states of the relay contacts are indicated by LEDs LD1–LD4 (see Figure 2-1 on page 3). When an LED is lit,
the contacts of the corresponding relay are closed. See the applicable indicator installation manual for information
on checking relay contact functionality.

Configuration 11
3.0 Configuration
Configuration of the external 320IS Plus is done through the SETUP menu of the attached indicator acting as the
master device.
All operating parameters are stored in the host indicator’s EEPROM memory, and can be edited after placing the
indicator in SETUP mode. See the indicator installation or operation manual for instructions on editing
configuration parameters.
The 320IS Plus works as the slave device of the indicator and will not work as a stand-alone unit. After both the
indicator and 320IS Plus are powered up, the module attempts to communicate with the indicator through the fiber
optic port and all necessary working parameters are sent to the 320IS Plus. All inputs and outputs function as
peripheries of the indicator. Communication must remain constant between the two devices for data to be
transferred through the various ports.
See Table 3-1 for parameters that are sent to the 320IS Plus during power up.
