PC-Programmable RTD, T/C, Ohms, mV
and Potentiometer Limit Alarm Trips

Introduction

This is the users’ manual for the Moore Industries
CPA PC-Programmable Alarm (TPRG: RTD, T/C,
mV, Ohms and Potentiometer Limit Alarm Trips). It
contains all of the information needed to confi gure,
install, operate, and maintain this instrument.

About this Manual

Wherever you see a “ Note”, “ Caution”, or “ WARNING
” pay particular attention.

WARNING - Hazardous procedure or condition that
could injure the operator.

Caution - Hazardous procedure or condition that could
damage or destroy the unit.

Note - Information that is helpful for a procedure,
condition, or operation of the unit.

The CPA

The CPA (TPRG) is a PC-Programmable, user­confi gurable alarm. The instrument includes two
alarm (relay) outputs and an optional analog output.
The alarms can be confi gured as trip or fault alarms.

Figure 1. The CPA (TPRG)

The CPA 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, per relay, 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 CPA, check for a tag affi xed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.

Inputs

Refer to Table 3 of this manual for input ranges and
accuracies of the CPA (TPRG).

Outputs

1PRG

This is a one relay output with a 5A@250Vac or
5A@24Vdc, 50/60Hz non-inductive contact rating. It
is available in a DPDT arrangement. All relay contacts
(NO, NC and COM) are available for use. No jumpers
are required.

2PRG

This is a two relay ouptut with a 5A@250Vac or
5A@24Vdc, 50/60Hz non-inductive contact rating.
The contact arrangement is SPDT. All relay contacts
(NO, NC and COM) are available for use. No jumpers
are required.

Options

Analog Output (-AO)

The analog output range of the CPA (TPRG) can
be voltage or current. The current output is a
confi gurable source or sink output. Four terminals
are provided to allow voltage/current and current sink/
source selection without the need for jumpers. The
output can be confi gured to narrower spans from the
PC Confi guration program. The range of the current
output is 0–24mA. The range of the voltage output is

-0.5–11V.

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.
