The CPT
The CPT is a PC-Programmable, user-confi gurable,
transmitter. The instrument includes an analog output
and an optional alarm (relay) output. The alarm can
be confi gured as a trip or fault alarm. The CPT has
a READY LED to indicate the health of the unit, an
INPUT LED to indicate the status of the input and a
dual color LED to indicate alarm status.
Model and Serial Numbers
Moore Industries uses a system of model and serial
numbers to keep track of all of the information on
every unit it sells and services. If a problem occurs
with your CPT, check for a tag affi xed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.
Inputs
The current input range of your unit is from 0 – 50mA.
The voltage input range is from 0.0 – 10V.
Outputs
The CPT has a factory confi gurable current or voltage
output. The curent output range is 0-20mA. The
voltage output is 0-10V. An Analog Output (-AO) is
standard. The current output is a factory confi gurable
sink or source. Please notify Moore Industries
of your required confi guration. The output may
also be confi gured to narrower spans from the PC
Confi guration Program.
TX Power
A transmitter excitation power supply is standard on
the CPT (HLPRG). You may access this at the TX and
COM terminals. This is a fi xed power supply at 23Vdc,
±3% and 24mA max.
Options
Relay Output (-C)
An optional Relay Output (-C) is available. This is
a one relay output with 5A@250Vac or 5A@24Vdc,
50/60Hz non-inductive contact rating. The relay
contact arrangement is SPDT. All relay contacts (NO,
NC and COM) are available for use. No jumpers are
required.
RF Option (-RF)
An RF option is also available. This version provides
30V/m RFI/EMI immunity compared to our standard
model which offers 10V/m RFI/EMI immunity.
