Description
Current Monitoring Relay
GEYA Current Monitoring Relay is a solid-state relay with SPDT silver cadmium oxide contact and quick-connect terminals. It features start-up inhibit adjustable hysteresis, multiple voltages, automatic or manual control and LED relay status indicator. Our Current Monitoring Relay is suitable for industrial, automation and process control.
GEYA Current Monitoring Relay is with current measuring through an internal shunt. Programmable latching or inhibit at a set level for mounting on DIN-rail following DIN/EN. It has an LED indication for relay, alarm and power supply ON. It can be used to avoid relay operation when not desired.
GEYA Current Monitoring Relay is a complete current solution that mounts directly to a DIN rail. It allows the user to monitor the current of one circuit and switch to another circuit in case of an overcurrent or undercurrent condition.
Our Current Monitoring Relay has an LED indicator. The green LED will on when power is applied to the input terminals, while the red LED blinks during a time-out and will turn ON when the output is energized.
Applications:
- Serves for monitoring heating in rail switches, heating cables, and consumption of one-phase motors indicate current flow.
Function Features:
- Adjustable delay 0.1 – 10 s to eliminate short current peaks.
- Flexible adjustment by potentiometer, choice of 6 ranges: AC 0.05-0.5A; AC 0.1-1A; AC 0.2-2A; AC 0.5-5A; AC 0.8-8A; AC 1.6-16A
- Power up delay.
- Possible to use for current scanning from the current transformer.
- Universal supply AC/DC 24 – 240 V.
- Relay status is indicated by LED.
- 1-MODULE, DIN rail mounting.
