925-0270 Rev G 5
1.0 Introduction
This version of the operator’s manual is intended for C-100 consoles with firmware v2.00 or newer.
The BinMaster Model C-100 is a compact control console for a network of BinMaster SmartBob sensors.
It can control from 1 to 120 SmartBob sensors with a few keystrokes or automatically by use of an interval
timer or external start input signal. It has a 4-20mA current output that, in conjunction with the external
start input, provides for a traditional interface to a PLC (programmable logic controller) or DCS (distributed
control system) system. The console was designed with a NEMA 4X rating, thus if it is properly installed
it will be protected from windblown dust and rain. Vessel configuration is quick and easy with a simple
and intuitive user-interface, configurable in either the English or Spanish languages. Measurement
formats can be displayed as headroom percentage, headroom height, headroom weight, product
percentage, product height and product weight. Vessel configuration and user settings are stored in non-
volatile memory and will be retained during a power failure.
The Model C-100 can interface with up to five BinMaster C-50 Expansion consoles on a dedicated RS-
485 network. The Model C-50 is for interfacing the SmartBob system to a PLC or DCS system. Each
Model C-50 expansion console supports up to 6 analog I/O cards, each with 4 ports, for a total of 24
analog I/O ports per C-50. With five C-50’s each SmartBob sensor can have its own I/O port. Each input
can be used for externally starting a measurement and each output provides for a 4-20mA current output
of the last measurement. For more information on the Model C-50, contact one of BinMaster’s application
specialists or go to www.binmaster.com.
2.0 Specifications
Power Requirements
Isolated 24VDC source with 2W (0.085A) minimum output.
A quality earth connection is also required on the power terminal. Although this is not needed for
power or normal operations, it is required for proper protection from lightning and other electrical
surges.
SB-485 Port
RS-485 at 2400 bps using BinMaster’s proprietary half duplex protocol A or B and supporting 1 to
120 SmartBob sensors on up to 4,000 feet of a quality twisted-pair shielded cable.
EX-485 Port
RS-485 at 19,200 bps using a proprietary half duplex protocol to communicate to BinMaster
Model C-50 expansion consoles on up to 4,000 feet of a quality twisted-pair shielded cable.
External Start Input
Continuous monitoring for a dry contact closure to initiate a measurement with a response time of
less than 1 sec.
4-20mA Current Output
Continuous 4 – 20mA current output with 16 bits of resolution into a maximum loop resistance of
700Ω. If weight calculations are DISABLED, the output level is relative to the last measurement
of a user-assigned vessel and its entered height. If weight calculations are ENABLED, the output
level is relative to the calculated weight of a user-assigned vessel and all its entered parameters.
An error condition (did not drop, bob stuck or communications error) can also be presented at this
output with a user-selectable value of either 2mA or 22mA.
