Loop Alarms™ Process/Alarm Switch From Love Controls

Loop Alarms™ Process/Alarm Switch accept inputs from process devices. SPDT relay outputs can be set for latching or non-latching, direct or reverse action and high or low function. Output behavior is easily programmable via switches. Mount in standard 11-pin sockets.


Isolation: 1500 Volts RMS between input, outputs and power.
Power Supply: 85-265 VDC/VAC, 50-400 Hz.
Setpoints: Adjustable from 0-100% of span.
Deadband: Adjustable from 0.25-100% of span.
Drift: ±0.02%/°C typical, ±0.05%/°C maximum.
Ambient Operating Temperature: 32 to 131°F (0 to 55°C) non-condensing.
Input Impedance: Voltage input=1 megohm, Current input=10 ohms.
Relay Output: SPDT, one set per setpoint, 5A @ 250 VAC resistive.
Latch Circuit Reset: Automatic at power up. Manual with reset switch.
Indicators: One dual color LED per setpoint; red = On, green = Off.
Dimensions: Including socket pins, 2-3/8"W x 3-7/16"H x 1-3/4"D (60.3 x 87.3 x 44.4 mm).
