Section 1 - Introduction
The SPA² Programmable Limit Alarm Trips provides on/off control, warns of unwanted process
conditions, alarm on rate-of-change and provides emergency shutdown. Very versatile, they accept a
signal input from transmitters, temperature sensors and a wide array of other monitoring and control
instruments.
This manual contains information needed to install, operate and maintain this product.
Overview
This is the user’s manual for Moore Industries’ SPA
2
includes the two model types:
HLPRG (high level)
- Programmable Current/Voltage Limit Alarm Trips.
TPRG
(low level)
- Programmable RTD, T/C, Ohms, mV and Potentiometer Limit Alarm Trips.
These instruments can be configured using front panel push buttons and/or a dedicated PC
Configuration Program. The SPA
2
monitors a process variable and provides up to four, fully user
configurable contact closure outputs that can be individually programmed to trip whenever the input
falls outside a user-set high or low trip point. The SPA
2
is typically used to activate a warning light,
bell or buzzer; or to initiate a system shutdown. Thus, the instrument acts as a simple, but highly
reliable and effective means of monitoring and safe-guarding a process. Detailed information is
highlighted within each section on the two models’ features, functions, and configuration.
Model Numbers and Options
The following section provides details of the Moore Industries model number and the available
options for the SPA
2
.
Moore Industries model numbers for the SPA
2
are structured as follows
SPA2 / HLPRG / 4PRG / U / -AO [DIN]
Unit / Input / Output / Power / -Options [Housing]
Inputs
HLPRG
- High Level Programmable. Programmable by the end-user to accept Current (at any range
between 0-50mA) or Voltage (at any range between 0-10Vdc).
TPRG
- Temperature Programmable. Programmable by the end-user to accept inputs from 23 RTD
types, 9 Thermocouple types, Resistance and Potentiometer devices, and direct Millivolt sources.
The SPA2 (TPRG) also has the capability of dual and triple sensor inputs. This is beneficial when you
choose to use and view either a differential or averaging RTD input and process variable.
Outputs
Alarms
The SPA
2
can be ordered with two (-2PRG) or four (-4PRG) contact closure alarms. Each alarm can
be individually programmed.
