2857-570/024-005 WAGO Terminal Blocks

Wago 2857-570/024-005 is an I/O unit designed as a 3-phase measurement module that operates on a supply voltage range of 16.8-31.2Vdc, with a nominal 24Vdc. It features push-in spring cage-clamp connections for easy installation and a 5A current input interface that can be configured via software. This unit does not operate on AC supply voltage and is designed to function within an ambient air temperature range for operation of -40°C to +70°C and for storage from -40°C to +85°C. It does not specify a control voltage but offers IP20 protection and communicates via Modbus RTU over RS-485. The unit has a net width of 72 mm and is designed for mounting on a DIN-35 rail, with dimensions of H90mm x W72mm x D55mm. It includes 3 x analog inputs for 377Vac / 480Vac and 4 x analog inputs for 5A, with a mechanical resistance configuration of I1-I2-I3-IN and a maximum continuous operating voltage for AC. The module supports a resistance of 50mA at 24Vdc nominal load and can operate in environments with 5-95% relative humidity, non-condensing.
