API Plug In Mounting Socket


• 26 field configurable input ranges
• DC Voltage Input: 0-50 mV to +/- 10 V
• DC Current Input: 0-1 mA to 0-20 mA
• Output: (2) SPDT Relays
• Field-Configurable by User

The API 1090 G accepts a DC voltage or current input and provides a visual alarm indication and two independent alarm outputs via SPDT relay contacts for each setpoint. 17 voltage and 9 current input ranges can be field-configured via external rotary and slide switches. Offset ranges such as 1-5 VDC and 4-20 mADC are also included. Consult the factory for other available ranges.
API exclusive features include a LoopTracker LED that varies in intensity with changes in the process signal, a bi-color alarm status LED, and a Functional Test Push button to toggle both relays independent of the input. The green LoopTracker LED varies in intensity with changes in the process input signal. Monitoring the state of this LED can provide a quick visual picture of your process loop at all times. The functional test push button toggles the alarm status independent of the input when depressed. It verifies the alarm and system operation and also provides the additional function of unlatching the alarm when the latching mode has been selected.
Heavy-duty relay contacts allow the module to directly control high capacity loads. The alarm outputs can be configured in the field for HI/HI, LO/LO, HI/LO or LO/HI operation, latching or non-latching, and normal or reverse acting. Topaccessible, multi-turn potentiometers are used to adjust the deadband from 1 to 100% and the alarm setpoints from 0 to 100%. 
This module includes an unregulated 18 VDC loop excitation supply that can be used to power an external loop-powered transmitter or other passive input device eliminating the need for an additional DC loop supply.
