The EFR 012 electronic hygrostat monitors relative humidity in enclosures and activates a heater when the set point is reached, with an integrated LED indicating operation. It has a relay output with a switching capacity of 8 A AC at 240 V for ohmic loads and 1.6 A AC at 240 V for inductive loads, and 4.2 A DC at 24 V for DC ohmic loads. The device operates at a fixed setpoint of 40% rF and is rated for 230 V AC. It mounts on a 35 mm DIN rail via clip, measures 2.5 in height, 1.7 in width, and 1.5 in depth, and uses a 5-pole clamp for 2.5 mm² wire connections. The housing is plastic to UL94 V-0, light grey, and it operates from 32 °F to 140 °F with humidity up to 90% rF.
The EFR 012 electronic hygrostat senses the relative humidity in an enclosure and turns on a heater at the set point, helping prevent the formation of condensation in the enclosure. The integrated LED is lit when the connected device is in operation.
