Short DescriptionFLOATLESS RELAY SINGLE TANK CONTROL 240VACFLOATLESS RELAY SINGLE TANK CONTROL 24VDCZELIO CONTROL RM35-HZ FREQUENCY CONTROL RELAY 40-70 HZ
Long DescriptionThe TFR-N monitors the levels of conducting liquids by using 3 probes as shown in figure. The operation is as follows: - On supply, the AMBER LED (Low) is lighted and remains lighted when the liquid level rises to contact with CO (1) & LO (4). - When the liquid level rises to probe HI (3) the GREEN LED goes off, the RED (High) LED is lighted and the relay energizes. - When the level drops below HI (3) the RED LED remains on and the relay remains latched. - When the level drops below LO (4), the RED LED goes off, the AMBER LED lights and the relay releases. The LEDs indicate the condition of the relay. For pumpin operation of tank, connect the starter through contacts 8 & 5. For pump-out operation of well, connect the starter through contacts 8 & 6.The TFR-N monitors the levels of conducting liquids by using 3 probes as shown in figure.

For pump-out operation of well, connect the starter through contacts 8 & 6This Harmony RM35-HZ control relay allows monitoring of frequency control. This modular control relay is ideal for monitoring of frequency variations in electrical power sources such as wind turbine and micro-power stations. It has one of market medium form-factors with 35mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 3-pole DIN device. It also offers a selectable memory function, integral LED for indicating control status, sealable cover, with simple and precise settings with screw trimmers. It provides an automatic detection of abnormal electrical values before they incur serious damage to machinery thus reducing your maintenance and downtime costs. Multi function controller for wide choice selected in hard-wired logic automated systems, ideal for refurbishment of old installations without using a PLC.
