1.1 PRODUCT DESCRIPTION

BLH Remote Digital Displays (Figure 1-1, 1-2)
receive and display serial ASCII data transmitted
by a BLH host LCp100, LCp-200, or Baldwin
Model 2020 series weight indicator/ transmitter.
Operating on supplied data, the Remote Display
precisely duplicates the weight, rate*, or tension
value display of the host device. Indication also
includes gross, net, and level information. Figure
1-1 shows a typical Remote Digital Display
application.

Units require only a twisted pair of wires for
interconnection and mount up to 2000 feet from
the host device. Remote Display units are ideally
suited for applications where analog panel meter
resolution is not adequate. Analog displays
present only an approximation of actual weight
data whereas serial communication guarantees
digit-for-digit replication. Precision accuracy,
easy installation, and optional NEMA or
explosion-proof enclosures make these units the
perfect choice for plant or control room remote
display.

Introduction

Figure 1-1. Typical Remote Display Application

Front panel ZERO and TARE keys transmit
push to zero and tare commands to the host
device. The GIN (gross-net-rate) key, however,
functions independently from the host device.
For example, a remote LCp-200R unit can
display net weight or rate while the host LCp­200 displays gross weight. CE Marked Remote
Digital Displays have passed both the EU
(European Union) Low Voltage and EMC Di­rectives.

1.2 MOUNTING OPTIONS

For units located in a general factory/plant floor,
or if corrosive, hose down, or sanitary
requirements are a factor, a NEMA 4X stainless
steel enclosure is available. For Div. 2
hazardous locations, units are available with FM
approval as a non-incendive device. For Division
1 hazardous locations an explosion proof en­closure is available.
