Annunciators

PD154: 4-Point Alarm Annunciator

The Vigilante II can be programmed for multiple sequences with first-out alarm indication. This feature indicates the first point of failure of a system when multiple alarms occur.

If multiple Vigilante II annunciators are connected for multiple unit first-out indication, only one input from all connected devices will display as a first-out alarm.

The Vigilante II Alarm Annunciator can be programmed for all common ISA sequences including A, F1A, F2A, F3A, M, F1M. Selectable ISA -1 (Silence Button), -4 (No Lock-In), and horn disable options.

PD158: 8-Point Alarm Annunciator

The Vigilante II can be programmed for multiple sequences with first-out alarm indication. This feature indicates the first point of failure of a system when multiple alarms occur.

If multiple Vigilante II annunciators are connected for multiple unit first-out indication, only one input from all connected devices will display as a first-out alarm.

The Vigilante II Alarm Annunciator can be programmed for all common ISA sequences including A, F1A, F2A, F3A, M, F1M. Selectable ISA -1 (Silence Button), -4 (No Lock-In), and horn disable options.

PD138: Temperature and Process Scanner

The MINIMUX® II is a microprocessor-based eight channel analog input scanner/multipexer 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

In its most basic form, the PD138 is the electrical equivalent of a double-pole, eight position automatic switch. Whatever input is brought into the PD138 is dwelled on for a certain amount of time while being channeled/switched out to another device. For example, a typical application may involve channeling/switching eight type J thermocouples into a single digital panel meter.

One of the most popular uses for the PD138 is temperature monitoring, especially the monitoring of bearing and stator winding temperatures. Any of the many different style thermocouples, RTDs, or thermistors can be used with the PD138 - right out of the box.

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.

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.

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.
