API 1420 G

Description

The API 1400 G and API 1420 G are factory configured for an

RTD input and provide alarm contact outputs. Heavy duty relay

contacts allow the module to directly control high capacity

loads.

The API 1400 G provides a single setpoint adjustment and

DPDT relay contacts. The normal acting alarm output can

be factory configured for HI or LO operation. Top-accessible

potentiometers are used to adjust the alarm setpoint and

deadband.

The API 1420 G contains two independent setpoints with

two SPDT relay contact outputs. The normal acting alarm

output can be factory configured for HI/HI, HI/LO, LO/HI or

LO/LO operation. Top-accessible potentiometers are used to

adjust each alarm setpoint. Deadband is fixed at 1% of span.

Adjustable deadbands are optional.

LoopTracker and Alarm Status LEDs

API exclusive features include a LoopTracker LED that varies in

intensity with changes in the RTD input signal.

A red/green bi-color alarm status LED (two on the API 1420

G) visually indicate alarm status. These LEDs provide a quick

visual picture of your process at all times.

Output Test

API's exclusive functional test button can be used to verify the

alarm and system operation. Press the Test button to toggle

the alarm relay(s) to the opposite state. The output test but-

ton greatly aids in saving time during initial startup and/or

troubleshooting.
