 One Series W Energy Limited Transmitter-Switches

The most compact of the One Series product family, the 2W, 4W and 8W models offer the most cost-effective means of upgrading an existing plant from blind mechanical switches. The 2W (2-Wire) loop powered models feature simple connections to the logic solver, utilizing the existing plant wiring. No power wiring is required. The 4W (4-wire) models provide more switching capacity Б─⌠ up to 10 amperes. The most versatile 8W models provide 2 set points and a 4-20 mA output.
