latches itself ON. The relay remains ON until you either set it to OFF
from the software or the momentary switch sets it to off.
The status of the light is available in the software if you use relays that
give feedback. In addition, the status light adjacent to each output lights
up if the output is ON.
Each relay is rated for any of the following lighting loads:
Note
Andover Controls does not recommend switching DC loads. Switching
DC loads can damage the relay.
• 20 A with a Tungsten filament at 125 VAC
• 20 A with a Ballast at 277 VAC
• 20 A with Resistive element at 277 VAC
The motor load is 1/2 horsepower at 110 to 125 VAC or 1/2 horsepower
at 220 to 227 VAC.
Andover Controls relays are prewired for the LCX 890 series of control-
lers and plug in to the 5-pin connector adjacent to each output.
LCX 898 outputs have 4,000 V noise immunity from IEC E801-4 and
ANSI/IEEE C 62.41 5 ns/50 ns EFT test waveforms.
Input Requirements
Caution
Andover Controls inputs are designed to be used with two-wire devices
and do not provide sufficient power to operate sensors requiring an
external power supply.
The LCX 890 controllers each have two types of inputs, digital and uni-
versal. The paragraphs that follow give the requirements of each type of
input.
