DIN Rail Devices

Description DIN rail devices serve as low–cost signal conditioning modules between the field device and the control system. The new enclosures mounted on the 35 mm standard rail are equipped with plug-in screw terminals. These make it easy to replace modules without interruption of the auxiliary power supply. Galvanic isolation and the amplifier properties are the assets of DIN rail devices. Equipotential earth as required with safety barriers is not necessary because of the inherent galvanic isolation. Due to the amplifier properties, fluctuations of the auxiliary power supply do not affect the performance of the measuring circuit. The plug-in screw terminals facilitate mounting of input and output leads as well as of the auxiliary power supply. Each terminal has a clamping capacity of two conductors of 1.5 mm2 cross–section each.

■ 1 or 2 channel 22.5 mm wide enclosure ■ Mounts on 35 mm DIN rail ■ Screw-plug in connectors for inputs, outputs and power supply ■ Safe galvanic isolation ■ Status LED ■ Low power consumption ■ EEx ia approved ■ Suitable for DCS and PLC ■ Horizontal or vertical mounting without gap (check ambient conditions) ■ International approvals

LEDs shows the status of the respective device. The operating mode is indicated by means of a green LED while yellow LEDs indicates the switching state, e.g. of switch amplifiers. Red LEDs signals fault conditions, e.g. a line break or short–circuit. When using DIN rail devices, the properties as an amplifier often allow you more freedom than the cumbersome considerations which are common with barriers would normally permit.
