An attractive modern designed conductive probe type level control relay in a din rail mounted modular style housing of 1.5 modules width (27mm). The MOD-W-1 is a transformer based conductive probe level control relay and is hence available in dedicated AC voltages only. The sensitivity is potentiometer adjustable 2-100 Kohms, also a potentiometer is fitted to adjust a delay on tripping timer 0.1-10 secs, useful to delay threshold tripping due to fluid movement in tanks. An eight way function switch is provided (designated A to H) to switch between "pump up" and "pump down" modes along with a relay proving function "permanent on" or "permanent off", the switch will also determine how the adjustable time delay will function. Regulation of two levels - pump down mode: The relay energises when the high level probe is reached and de- energises when the level falls belowthe low level probe. Regulation of two levels - pump up mode: The relay de- energises when the high level probe is reached and energises when the level falls below the low level probe. Regulation of one level - pump down mode selected: Connect the maximum and the common terminals together. In this case a single probe only is used and the relay operates when the probe is immersed.

Din rail mounted or 8/11 pin plug in conductive probe level control relays for the control of maximum and/or minimum levels of conductive liquids. Regulation of two levels "pump down" mode -The relay is energised when the high level probe is reached and de- energises when the level falls below the low level probe. Regulation of two levels "pump up" mode -The relay is de-energised when the high level probe is reached and energises when the level falls below the low level probe. Regulation of one level "pump down" mode selected -Connect the maximum and common terminals together. In this case a single probe only is used and the relay energises when the probe is immersed. Or in "pump up" mode the relay operation is reversed. Prove relay test feature/override -With probes connected the front selector switches can be used to control the relay providing a permanent "ON" or permanent "OFF".
