FF
Dual setpoint 0.1-10V DC relay. Providing two separately controllable trip levels. With R1 selected as the “High” level and R2 as the “Low” level. When the monitored signal voltage rises above R2 set level R2 relay will energise. If the voltage continues to rise above R1 set level, relay R1 will energise. Conversely as the monitored voltage falls R1 will de-energise, if the fall continues R2 will de-energise. The unit has a built in fixed hysteresis of 2% at each setpoint to avoid relay “chatter”. The YWRU2T does not have a latched option and is therefore “auto” reset on both relays.
DC Auxiliary Supply Versions
DC auxiliary supply versions are as standard non isolated. For these versions the supply and the measured current must be isolated from each other and must not exceed 50V DC. On request at extra cost isolated versions can be manufactured utilising internally a DC to DC converter.
