Page 11: Models
Chapter 2.0 Models METTLER TOLEDO offers one standard plastic housing model of the IND110 Signal Converter. The IND110 is not suitable for mounting into a harsh environment without a protective enclosure. Figure 1 An optional stainless IP66 rated enclosure with gasket is available separately and is shown below.
Page 12 IND110 Technical Manual An optional cast aluminum explosion proof (Flameproof) enclosure is available when installation in hazardous areas is required by ordering part number 17041800A. It is rated by the manufacturer for use in a Class I Group C,D; Class II Group E,F,G; Class III environment when installed per the manufacturer’s recommendations.

Page 17: Installation
Installation Load cell connections Up to (4) 350 Ohm full bridge strain gauges may be connected in parallel. The excitation voltage supplied by the IND110 is 10 VDC with a source current of 120mA max. WARNING THE IND110 IS NOT INTRINSICALLY SAFE. THE LOAD CELL LINES MUST NOT BE OPERATED IN A HAZARDOUS AREA WITHOUT AN APPROVED INTRINSIC SAFE BARRIER.
Page 18: Load Cell Selection
IND110 Technical Manual Load cell Selection Before any load cells are connected, determine if intended load cells will work correctly. 1. First identify • Full scale system capacity. Example: If system span is 0 -10,000 lbs, then 10,000 is the capacity.
Page 19: Module Mounting Details
IND110 Technical Manual Module mounting details Enclosure installation details The enclosures illustrated below do not address hardware mounting/ wiring needs. The stainless enclosure has two plastic cord bushings to pass cables into the enclosure. The plugged openings are provided for wiring flexibility, if needed. The installer must provide correct fittings according to National and local codes.
Page 20 IND110 Technical Manual The views below illustrate module installation into the Nema 7/9 optional explosion proof enclosure. It snaps onto the DIN rail in the same manner as above but because of space limitations, snap the module onto the DIN rail first and then install into the enclosure.
Page 21: Analog Output 4/20 Ma Connections
Test for process control equipment ground continuity before wiring is completed. If it is not grounded, connect the IND110 at the load cell shield terminal to earth ground. If it IS connected to ground, be sure the IND110 wiring is NOT grounded.
Page 22: Power Supply Wiring
IND110 Technical Manual Power supply wiring The IND110 is provided with 20-28 VDC power input terminals. The user must provide a class II rated 24 VDC power supply. A class II power supply is voltage and current limited so short circuit conditions do not become dangerous.
Page 23: Setpoint Output Connections
IND110 Technical Manual Setpoint Output Connections The IND110 has two open collector transistor outputs. The LO output is turned ON when the load cell signal is below the LO setpoint and OFF (open collector state) when it is equal to or above the LO setpoint. The HI output operates in an identical manner controlled by the HI setpoint.

Page 25 IND110 Technical Manual Calibration Calibration is done with DIP switches 1-4 and the three buttons. For normal weighing all the DIP switches are OFF. For calibration, DIP switches 1-4 are switched ON as required to calibrate the weigh mode ZERO, weigh mode SPAN, LO setpoint cutoff and HI setpoint cutoff.
Page 27: Service
Chapter 6.0 Service Before servicing an IND110, make sure the power has been removed. There are no field serviceable parts within the IND110. WARNING DISCONNECT ALL POWER TO THIS UNIT BEFORE INSTALLING, SERVICING OR CLEANING. FAILURE TO DO SO COULD RESULT IN BODILY HARM...
