PD138 Temperature and Process Scanner

PD138 Temperature and Process Scanner

The MINIMUX® II is a microprocessor-based eight channel analog input scanner/multiplexer and annunciator that provides low-cost automatic switching for multi-point display and alarm systems. Each MINIMUX® II can automatically switch up to eight inputs to another device such as a digital panel meter, controller, or PLC. Signal switching is done via reed relays making the MINIMUX® II ideal for switching thermocouples, RTDs, control loops, and AC & DC signals.

Features

8 Inputs per Unit, Eliminates Need for 7 Displays
Unlimited Number of Units per System
Free Custom Message Labels
Thermocouples, RTDs, Process, AC & DC Inputs
Adjustable Dwell Time for Each Channel
Independent Alarm Input for Each Channel

First-Out Alarm Indication

Alarms Indicated by LEDs, Built-in Horn, and Relay
Built-in 85 dB Horn with Silence Pushbutton
Stop-On-Alarmed Channel (Field Select)
Non-Interruptible 4-20 mA Inputs
Sunlight Readable Indication
NEMA 4X/IP65 Front
Shallow Depth 1/8 DIN Enclosure
-40 to 65°C Operating Temperature Range

Automatic or Manual Scan

The PD138 automatically scans through each active channel, dwells on that channel for an independently programmed dwell time, while at the same time switching the signal to an external device. The scanning can be stopped, or scanned manually via the front panel stop/go pushbutton.

Alarm Annunciator

One of the key features of the PD138 is its ability to indicate and process alarms that are generated by an external device. Each channel of the MINIMUX® II has an independent ‘Alarm-in’ terminal that allows an external device to trigger an alarm on the MINIMUX® II. The external device may be the relays on a digital panel meter, such as the PD765, or the digital output from a PLC.

First-Out (Sequence F2A)

The PD138 can be configured to recognize first-out alarms. On the PD138, these are one or more alarms that occur during the first complete scan where an alarm is present on one or more channels.

PDS178 Temperature & Process Scanning & Alarm System

PDS178 Temperature & Process Scanning & Alarm System

We packaged our most popular PD138 product combination for you at a significant savings vs. buying these components separately. The PDS178 is a kit that includes a PD765-6R2-00 Trident and PD138 MINIMUX II in a PDA2821 NEMA 4X enclosure. The PDS178 is a Temperature or Process Scanning and Alarm System ready to wire into your application. You can’t beat the discounted package price!

The Watchdog Temperature Scanning & Alarm System brings together a popular combination of Precision Digital products: the Trident meter, the Minimux II Scanner, and a PDA2821 NEMA 4X enclosure.

The scanner provides low-cost automatic switching for multipoint display and alarms. Signal switching is done via reed relays making the Watchdog (as configured) ideal for switching up to eight thermocouple or RTD inputs. The Watchdog can be used in a variety of temperature monitoring applications. A very common application for this system is to monitor bearing temperatures (as shown above).

Because of the popularity of this combination, we can offer this system at a price significantly below what it would cost to buy these components separately.
