Used for 48 VDC logic solver inputs, this new One Series 2-Wire model is compatible with PLC and DCS inputs that expect a 48 VDC signal from the switch. These types of inputs are found in some legacy power plants that use a battery back-up for their control system. This new model is ideal for upgrades at power plants with 48 VDC control systems.

The One Series 2W4D is currently available with all sensor types and ranges. When placing an order, please use model code 2W4D00 and then append the sensor type and range. The One Series 2W4D model is a true 2-wire switch, so no separate wiring is required for power and is similar to the 2W2D and 2W3A models. The difference is the voltage range that this model operates over: 30-56 VDC @ 40 mA maximum.

Please note that there are no agency approvals available with the One Series 2W4D model. The product nameplate will show the basic product configuration and specifications but no agency approvals.
