Series PCP Relay/Controller/Power Supply 10A SPDT Relay, 24 VDC Power Supply, Latching Circuit for Level Control The Series PCP Level Controller is designed to be a power supply, an external relay, and a latching relay for differential level control with two level switches. As a power supply the PCP can step down line voltage to 5 or 24 VDC to power NPN switches such as the OLS and PC level switches or to power a transmitter. The PCP can function as an external relay to increase switching capability by providing up to a 10A SPDT contact for direct control of moderate loads. As a latching relay the PCP can be used with any two normally open level switches and provide level control for pumps. The latching circuit can also be used to hold the relay in an actuated state until manually reset. | |||||||||
Series LTP Single & Three Phase Solid State Relays Zero-Crossover or Phase Angle Fired Love Controls LTP Series Solid State Relays allow easy control of most resistive and some inductive loads. Available in zero-crossover or phase angle fired versions, these compact solid state relays fit in many applications. High efficiency heat sinks allow for compact size. Combined with a convenient DIN rail mount, these SSRs will fit where others won't. The LTT SSR Monitors and LTTJ Current Transformers mount conveniently on any of the single phase LTP Series SSRs. | |||||||||
Series SLD Single Channel Leak Detection Relays Shaft Seal Leak Protection Series SLD Single Channel Leak Detection Relay is used to monitor the shaft seal of a submersible pump to detect a leak before pump failure. A leak is detected by sensing the status of a float or conductivity switch installed in the seal cavity. When this resistance drops below the set sensitivity, the output relay energizes and the LED indicator illuminates. The SLD offers normally open and normally closed relay contacts to energize an alarm and de-energize the pump in the event of a leak. When the seal failure condition clears, the relay automatically resets. The SLD is available in three different sensitivities, two of which, are adjustable. All models utilize a 120 VAC control voltage. Installation is made simple with the standard 11-pin socket mount. | |||||||||
Series SSR Solid State Relays 5 or 10 Amp, SPST Switch Operation Series SSR Solid State Relays amplify the current handling capability of a variety of sensors for controlling higher power loads. The relays are compact, totally encapsulated and impervious to shock or vibration. Units feature SPST, normally open switch operation and can control loads up to 5A or 10A depending on model. Models SSR-312 and SSR-324 are specifically designed to provide low current "start-stop" or "on-off" switching for industrial motor, liquid level, and other control systems. Units hold operational state up to a 1/2 second during momentary power loss to cut nuisance shutdowns. | |||||||||
Model SSR-15 Intrinsically Safe Relay SPST Switch Operation, 5 Amp Model SSR-15 Intrinsically Safe Relay offers low power switching with solid state reliability and eliminates explosive conditions. Units are completely encapsulated and impervious to dust, moisture, or foreign material. Model SSR-15 can be mounted in any orientation and is shock and vibration resistant. | |||||||||
Model LDT Leak/Over Temperature Detection Relays Shaft Seal Leak and Stator Temperature Monitor The Model LDT is used to monitor the shaft seal and the stator temperature of a submersible pump to detect a leak or over temperature before pump failure. A leak is detected by sensing the status of a float or conductivity switch installed in the seal cavity. When this resistance drops below the set sensitivity, the output relay energizes and the LED indicator illuminates. When the seal failure condition clears, the relay automatically resets. A normally closed temperature switch mounted on the stator detects over temperature. The temperature safety feature incorporates a bistable relay that retains its position during power loss and latches on until the remote reset button is pressed. The LDT has adjustable leak sensitivity from 1k to 35k ohm. Installation is made simple with a surface mount configuration. | |||||||||
Series DLD Dual Channel Leak Detection Relays Shaft Seal Leak Protection Series DLD Dual Channel Leak Detection Relay is used to monitor the shaft seals of two submersible pumps to detect a leak before pump failure. A leak is detected by sensing the status of a float or conductivity switch installed in the seal cavity. When this resistance drops below the set sensitivity, the output relay energizes and the corresponding LED indicator illuminates. The DLD offers normally open relay contacts to energize an alarm or de-energize the pump in the event of a leak. When the seal failure condition clears, the relay automatically resets. The DLD is available in two different adjustable sensitivities. All models utilize a 120 VAC control voltage. Installation is made simple with the standard 8-pin octal mount. |
