Turck IM18-4DI and IMX18-4DI isolating switching amplifiers

The Turck IM18-4DI is a compact, four-channel isolating switching amplifier for non-Ex areas, while the IMX18-4DI is for IECEx areas. Packing four signals into an 18 mm module, the devices offer high channel density, making a difference for installations in small control cabinets and decentralised or modular automation systems. Users also benefit from the flexibility of a configurable dual 1:2, 1:3 or 1:4 splitter and reversible switching outputs.

With a width of 18 millimetres for four channels, the IMX18-4DI devices need almost a third less space on the DIN rail than similar installations with two-channel devices. The SIL2 certification of the devices together with Turck’s SIL proximity switches enables the creation of safety-rated applications.

Signal cables are connected with spring-loaded or screw terminals. The Power-Bridge variants can also be supplied from the rear via the DIN rail. A group fault signal contact makes it possible to indicate error messages.
