Absolute Process Instruments API 1700 G _ Frequency input single alarm

Features with all optional accessories:

Accepts Most Types of Pulse Signals
Field Adjustable Trip and Reset
Plug-In Design for Fast Installation
Input LoopTracker® and Alarm Status LEDs
Alarm Test, Optional Reset Button

Applications:

Machinery Speed Alarm
Redundant or Backup Alarm
Conveyor or Machine Malfunction Alarm

The API 1700 G are factory configured for a frequency input and provide alarm contact outputs. Heavy duty relay contacts allow the module to directly control high capacity loads.

The API 1700 G provides a single set point and reset point adjustment and DPDT relay contacts. The alarm output can be factory configured for HI or LO operation, non-latching or latching, normal or reverse acting. Top-accessible potentiometers are used to adjust the alarm trip and reset points.

LoopTracker and Alarm Status LEDs

API exclusive features include a LoopTracker LED that varies in intensity with changes in the frequency input signal. A red/green bi-color alarm status LED visually indicate alarm status. These LEDs provide a quick visual picture of your process at all times.

Output Test/Reset

API's exclusive functional test button can be used to verify the alarm and system operation. The output test button greatly aids in saving time during initial startup and/or troubleshooting. The HT latching option provides the additional function of unlatching the alarm when the reset button is pressed. The alarm will reset if the alarm condition not longer exists.
